The Ultimate Guide to Pillow Block Bearing Size Charts

Pillow block bearing is a bearing used in low torque, light load applications. It consists of a mounting bracket or pillow block that houses the bearings. The spherical rolling elements in pillow block bearings have a smaller contact surface with the bearing raceway, which reduces friction. Low friction allows pillow block bearings to operate at higher speeds, but with lower load capacities than roller bearings. Bearing housings are available in a variety of configurations and are mounted on a surface parallel to the shaft to which the bearing is mounted. The bolt holes are usually slotted to allow for adjustment during installation. Pillow block bearing allows the shaft to rotate smoothly while the base supports the load. If you buy Pillow block bearings, you most likely already have some information about them. For those who are not familiar with pillow block bearing, we will use this article to introduce the basics of pillow block bearing.

The function of pillow block bearing

Pillow block bearing plays a key role in mechanical equipment. It not only supports the power system and main parts of the equipment, but also helps the equipment operate smoothly and reduce equipment damage. Therefore, choosing the appropriate pillow block bearing is one of the important factors to ensure the efficient and stable operation of the equipment. It is also a key factor to ensure the life and reliability of the equipment.

Application of pillow block bearing

Due to its excellent structural characteristics, pillow block bearing is widely used in various mechanical equipment, such as metallurgical equipment, mining equipment, water pumps, fans, machine tools and other fields. At the same time, pillow block bearing can also withstand certain radial and axial loads, so it is also commonly used in automobiles, motors and other industries.

Agriculture: used in agricultural machinery such as tractors and harvesters.
Mining and Construction: Heavy machinery and construction equipment employed in mining operations.
Food Processing: Suitable for food grade applications, providing hygiene and durability.
Manufacturing: Used in conveyor systems, assembly lines and automated machinery.

Housing bearings must comply with industry standards and regulations to ensure quality and safety. Some widely recognized standards include those developed by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO).

Pillow block bearing bearing specifications

Shaft Diameter – The diameter must match the appropriate bore diameter of the bearing unit. Properly sized pillow block bearings slide easily onto the shaft and into position, ready to be secured with a locking device.
Shaft Height – Shaft height or backing height is determined by measuring the distance from the base of the pillow block bearing to the center of the shaft.
Shaft Size – The maximum diameter of the shaft or the diameter of the bore into which the bearing is mounted.
Maximum Speed – The maximum shaft speed a bearing is designed to allow for operation.
Maximum Load – The dynamic load capacity of a bearing capable of carrying both radial and thrust loads, or the maximum allowable radial load of a bearing capable of carrying radial loads only. The load rating varies with shaft speed. Consult the manufacturer for load ratings at various shaft speeds.

UCP Series Pillow Block Bearing Size Chart

The UCP series of seated outer spherical bearings is a representative form of seated outer spherical bearing components. Among them, the bearing seat P refers to the flat bottom solid. This series has two types: UCP200 and UCP300. The UCP300 series carries a larger load than the UCP200 series. Because there are reinforcement ribs at the root of the bearing seat installation part, it is a high-strength structure for loads in all directions. In addition, the bearing seat P can also be used with UK, UEL, NA series bearing assemblies, and UK assemblies with tapered bores (UKP). The nominal model number of the applicable adapter sleeve is appended to the component engineering model. Main uses of UCP series Pillow Block Bearing: transmission devices, fitness equipment, harvesters, etc.

TAKE-UP Pillow Block Units: UCT series Dimensions Chart

The outer spherical bearing UCT with slider seat is a bearing assembly composed of a bearing and a bearing seat with guide grooves. Bearing seat T can be assembled with UK, UEL and other components. There are two chutes on the upper and lower sides of the bearing seat, which can move back and forth on the frame. Therefore, it is most suitable for occasions where the distance between shafts needs to be adjusted. The shafts can also move while the machine is running. The UCT300 series bears a greater load than the UCT200 series. This type of seated spherical ball bearings are mostly used on drive shafts such as belts and chains.

4. The bearing seat is painted using an environmentally friendly powder plastic spraying production line;

5. The raw materials of the bearing rings are produced from high-quality bearing steel from Xingcheng Steel Plant and Daye Special Steel. In particular, the inner and outer rings of medium and large-sized bearings are made of forging blanks, which are then turned by precision CNC lathe turning lines;

6. Then the bearing rings will be sent to the protective atmosphere heat treatment production line for quenching heat treatment and tempering treatment. Especially large-size bearing rings adopt advanced salt bath quenching process, which greatly ensures the inherent quality of the bearing rings and makes the bearings durable. Longer service life and higher reliability;

7. After heat treatment, the ferrules must be sent to the material metallographic testing laboratory for strict metallographic and hardness testing;

8. The grinding processing equipment of the bearing rings uses high-precision special CNC grinders to ensure the accuracy of each surface of the bearing rings, so that the bearings have low friction resistance and high rotation accuracy when rotating.

9. The important surfaces of the inner and outer rings of the bearing must be tested for roundness using a high-precision roundness meter. In addition, it is equipped with a precise profile and roughness inspection instrument for precise detection of the shape and roughness of the grinding surface;

10. The bearings are assembled using a variety of automated equipment such as fully automatic ultrasonic cleaning, automatic bearing assembly, automatic grease injection, and automatic capping;

11. The finished bearings are strictly tested for three items: rotation accuracy, bearing radial clearance, and bearing vibration and noise level. The vibration and noise level of the bearing has stably reached the V2 level requirements.
