The Ultimate Guide to Tapered Roller Bearings

Tapered roller bearings are an important bearing option for many types of mechanical components. They allow radial and axial loads to act on the bearing assembly simultaneously. The unique feature of tapered roller bearings is the tapered geometry of their rollers. It is aligned with what is commonly called a cone, and the corresponding raceway of the outer ring. The design ensures optimal load distribution along the length of the roller, resulting in increased strength and reduced stress concentrations. The angle of taper is critical and determines the bearing’s ability to handle various axial and radial loads. Tapered roller bearings concentrate combined loads onto a central rotating axis. The axial load carrying capacity of tapered roller bearings increases with increasing raceway contact angle – their conical shape results in less overall stress on the interface components. We’ll take a closer look at the various types of tapered roller bearings, including single-row, double-row, and four-row configurations, and how each offers unique advantages for specific applications.

What are tapered roller bearings?

Tapered roller bearings are separable bearings. The rollers taper into a conical shape, and the corresponding raceways they connect are angled to accommodate their tapered form. The rollers themselves are held in cages that fit the inner and outer rings. The cage of a tapered roller bearing is somewhat different from the cage of other types of bearings. The most common cage type for tapered roller bearings is the pin cage. rollers result in greater load capacity but reduce the bearing’s speed, dynamic loading, vibration and deceleration capabilities. Tapered roller bearings are divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed.

Tapered roller bearing loads

Due to their large contact surface area, tapered roller bearings are able to withstand heavy axial and radial loads. The angle and tapered shape of tapered roller bearings minimize stresses caused by the combination of radial and axial loads. Radial and axial loads often combine to produce combined loads on the bearing assembly. The ability to handle angular and varying angular loads has made tapered roller bearings an integral part of a variety of technical designs and industries. The tapered shape of the rollers essentially concentrates radial and axial loads into a unified load that is easier to exploit. They can harness a variety of forces by configuring two or even tapered bearings.

The angle formed by the line of contact between the outer ring and rollers and the axis of the bearing bore determines the type of load for which the bearing is best suited. The larger the angle, the better the bearing is able to handle thrust loads, but the ability to handle radial loads is proportionally reduced. Bearings equipped with single row tapered rollers can only bear axial loads in one direction. The steepness of a roller bearing’s inclination increases the thrust/axial load it can handle, while the small angle increases the radial load capacity. As the radial load increases, the bearing experiences greater stress on the sides of the bearing raceway. A shallower angle minimizes stress, thereby reducing stress on the rollers.

Types of tapered roller bearings

Different types of tapered roller bearings are suitable for different types of loads and rotational speeds. Here are several common tapered roller bearing types and their characteristics.

Single Row Tapered Roller Bearings

Single row tapered roller bearings have excellent design attributes. Single row tapered roller bearings typically have a one-piece stamped steel cage that secures the rollers to the cone and space them evenly for smooth operation. The most common tapered roller bearings of the 320 and 302 series are widely used and provide a balanced combination of strength and flexibility, making them a standard option in automotive wheels, transmissions and conveyor systems. Other applications include vehicle front wheels, differential and pinion configurations, transfer rollers, machine tool spindles and trailer wheels. Very popular trailer wheel size combinations include LM11949/LM11910, LM11749/LM11710 and L21549/L21511. Of course, there are many other bore and outer diameter tapered roller bearings available.

Double row tapered roller bearings

Double row tapered roller bearings, such as the 375D – 374 and NA776 – 774D series, are designed for heavy-duty applications and excel due to their enhanced load-carrying capabilities. Available in two main configurations: TDO (double outer ring) and TDI (double inner ring), these bearings provide a robust solution for industrial gearboxes, rolling mills and mining equipment where radial and axial loads are high.

Matched Tapered Roller Bearing

The products of matched single row tapered roller bearings are based on the common dimensions of single row tapered roller bearings. Depending on the application requirements, matched tapered roller bearings are available in different designs and variants. Depending on the design, paired bearings are suitable for heavy radial and axial loads. The axial load capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle is usually between 10° and 30°. The size of the angle is related to the calculation coefficient e: the larger the value of e, the larger the contact angle. Depending on the design, paired bearings position the shaft axially in both directions, with a specific axial clearance or bearing preload.

Four row tapered roller bearings

Four-row tapered roller bearings combine the inherent high load radial/thrust capabilities and direct/indirect mounting variables of tapered roller bearings into an assembly that provides maximum load ratings in the smallest space. In addition, precision applications such as machine tools, pumps and compressors often rely on matched and square bearings. These bearing sets, part numbers 30207JR/30207J2/Q and 32020 X/QDF, consist of two or four tapered roller bearings that are precisely matched during the manufacturing process. This ensures high accuracy and even load distribution, which is critical for applications where alignment and accuracy are critical.

Thrust tapered roller bearings

Thrust tapered roller bearings bear mainly axial load and radial combined load, but the radial load shall not exceed half of the axial load. Compared with other thrust roller bearings, the friction factor of this kind of bearing is relatively small. Low, the speed is relatively high. It can reduce the relative sliding between rollers and raceways during operation, and the rollers are long, large in diameter, large in number, and have high load capacity. Oil lubrication is usually used. It has a larger axial load capacity than a thrust ball bearing, is rigid, and occupies relatively less axial space. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low-speed applications, and their speeds are slightly higher than thrust cylindrical roller bearings.

Advantages of tapered roller bearings

High load capacity

Tapered roller bearings are capable of carrying heavy radial and axial loads. Their design allows them to withstand significant weight, making them ideal for applications involving high load conditions.

Handle combined loads

Due to their geometry, tapered roller bearings have distinct advantages over spherical, cylindrical and needle roller bearings when handling combined and varying loads. The tapered design enables tapered roller bearings to efficiently carry combined loads (radial and axial). This ability is critical in applications where the bearings can handle two types of loads simultaneously.

long life

Tapered roller bearings are known for their long life. The ability to effectively handle load stresses helps extend service life and reduce the need for frequent replacement. Tapered roller bearings are highly reliable when used correctly. Cars can travel hundreds of thousands of miles without tapered bearing failure and require little to no maintenance.

misalignment adjustment

Tapered roller bearings can withstand minor misalignments that can occur due to shaft deflection or installation errors. This feature provides a degree of application flexibility and reduces wear.

Versatility

Due to their robustness and load-handling capabilities, they are suitable for a wide range of applications from automotive axles to heavy machinery.

Disadvantages of tapered roller bearings

Speed: Since the rollers maintain a high surface area of contact, this is an advantage in some ways (such as evenly distributing loads). But its speed is much lower than that of ball bearings.

Dynamic misalignment: Aligning ball bearings are tolerant of dynamic misalignment than tapered bearings. Because tapered roller bearings are designed for specific angles, they respond poorly to gradients beyond what they were designed for. Aligning ball bearings can handle temporary movement without putting too much stress on the equipment because the balls float independently within the cage. With a tapered roller, any pressure exerted on it is thoroughly distributed throughout the assembly.

Criteria for selecting tapered roller bearings

Tapered roller bearings are the most common solution for carrying combined loads.

Non-combined forces: Ball bearings and other simpler alternatives generally have less friction and may be sufficient for non-special uses that lack combined forces or require high surface area contact.

Determine load capacity: Contact angle determines load capacity, so it is important to determine the load angle the bearing can withstand. For heavy-duty applications, multi-row tapered bearings are required to handle the combined loads. For lighter forces, one is usually enough.

Combined Forces: A combination of axial and radial loads almost always requires a tapered roller bearing.

Determining the contact angle: The contact angle between the component and the bearing will determine the outer ring raceway angle. A larger contact angle means a higher axial load capacity and vice versa. When selecting the correct tapered bearing for your needs, you will see that this angle is often expressed by a coefficient “e”; higher numbers indicate greater contact angle and axial load capacity.

Generally speaking, for applications with heavy radial loads, angles of 10° to 19° are very common. For angles less than 10° you should consider whether full thrust roller bearings are required and investigate whether there are significant radial forces. As axial loads increase (radial loads decrease), 20° and 24° are a good balance. This angle is small enough that radial loads still don’t put extreme stress on the bearings, but steep enough to handle axial loads efficiently. For larger axial loads, an angle between 25° and 29° is required, where radial loads produce wear and shorten component life. Nonetheless, it is still powerful enough to handle large combined radial and axial loads simultaneously.

Reasons for tapered roller bearing failure

If a tapered roller bearing is not assembled with care or incorrect tools are used, wear and other forms of damage can occur. We’ve listed the most frequently asked questions.

wear and tear

Sand or small metal particles can get between the bearings and cause damage to the raceways. This may shorten the life of the tapered roller bearing or cause the bearing to become misaligned. In the long run, this wear and tear can also affect other parts of the machine. Foreign matter can get in because an incorrect filter is used or the housing is not 100% clean during assembly.

Dits and dents

The same hard particles can cause pits and dents in bearings and raceways. Metal particles or dirt, such as sand, can prevent you from getting the most out of your tapered roller bearings. Further, there is a chance that you will have to replace them soon.

Corrosion

Since moisture can be deposited in the bearings, corrosion can occur. This mainly occurs when tapered roller bearings are subjected to temperature changes. Moisture can get in due to damaged bearings or too little lubricant being used during assembly. Failure to adequately dry bearings after cleaning or inspection can also lead to corrosion. If you are not using the bearings for a while and decide to store them, it is wise to cover them with oil. Wrap them in protective paper and store in a dry place.

Wrong or insufficient lubricant

Due to insufficient lubricant, the metal parts of the bearings rub against each other. As a result, discoloration may occur due to heating. Metal can also peel or scratch. Without enough lubricant, friction can generate too much heat, causing the ends to deform. In the worst case, friction (and therefore heat) can cause a tapered roller bearing to completely deform, causing it to warp. The bearing may even end up being completely damaged.

Overconfidence or overload

Excessive preload can generate a lot of heat and cause damage. This damage is similar to that caused by using too little lubricant. During assembly, remember that ordinary lubricants may not be suitable for heavily preloaded bearings. Another type of damage can be caused by excessive preload, even if you use the proper lubricant. Heavy loads can cause premature fatigue of the underside metal. This occurs depending on how high the preload you give the bearing relative to the capabilities of the tapered roller bearing.

Axial clearance is too large

Excessive axial clearance creates excess space between cylinders. This can cause the cylinder to slip and warp. This can cause wear and tear.

Bearing cage damaged

Careless use and use of unsuitable tools during assembly may result in damage to the cage. The solution to this problem is difficult to explain. Therefore, we recommend that you contact us.

To prevent all these forms of damage and get the most out of your tapered roller bearings, it’s especially important to use the correct materials. You also need to correctly (dis)assemble the tapered roller bearing. For example, use gloves. Sweat on your fingers can cause corrosion. Gloves can prevent this from happening.

Applications of tapered roller bearings

Tapered roller bearings are commonly specified for a variety of applications because they can effectively manage radial and axial loads.

Automotive

In the automotive industry, tapered roller bearings play a key role in wheel hubs, where they bear the weight of the vehicle (radial load) while also carrying the cornering forces (axial load). The dual load capacity of these bearings ensures smooth and reliable vehicle operation, especially when turning and shifting gears. Tapered roller bearings play a vital role in absorbing the forces generated during gear changes and the transmission of power from the engine to the transmission and differential wheels. Since cars need to withstand loads of different directions and magnitudes, the high load-carrying capacity of tapered roller bearings makes them a suitable choice.

Aerospace

Tapered roller bearings are exposed to extreme conditions in aerospace applications. Jet engines require bearings that can withstand high rotational speeds and temperatures, while landing gear bearings must withstand huge shock loads during takeoff and landing. These bearings are designed to handle these stresses, ensuring the safety and reliability of critical aerospace components. In the aerospace field, it is widely used in key components such as aircraft engines, landing gear, and aircraft hubs. They can handle complex loads.

industrial machinery

In industrial environments, such as steel mills or mining operations, tapered roller bearings are subject to heavy and constant loads. Rolling mills require bearings that can withstand high radial and axial forces during the metal forming process. Construction and engineering machinery such as excavators, bulldozers and cranes operate in harsh environments. Can provide reliable support under heavy load and vibration conditions. These heavy-duty machines rely on the robustness and load-carrying capacity of bearings for continuous and efficient operation.

Precision machine tools

In precision machine tools, bearings play a vital role in accurately handling high-speed rotational motion. They support the machine’s spindle, ensuring precise positioning and smooth operation of the cutting tools. Precision is critical to achieving the fine tolerances required for CNC machining and other high-precision manufacturing processes. Precision machine tools require bearings that can accurately handle high-speed rotational motion to achieve precision. Bearings support the machine tool’s spindle, ensuring precise positioning and smooth operation of cutting tools, as well as the tolerances required in CNC machining and other high-precision manufacturing processes.

Tapered roller bearings are designed to perform well in a variety of challenging environments, whether carrying heavy loads in industrial machinery, withstanding high speeds and temperatures in aerospace components, or ensuring precision in automotive and machine tool applications.

In addition to the above-mentioned industries, tapered roller bearings are also used in agricultural machinery, wind turbines, oil and gas equipment, heavy trucks, large machinery, etc. Overall, the exceptional load-carrying capabilities and adaptability of tapered roller bearings make them critical components in a variety of industrial applications.
