Types of Bearings by AUBEARING
Miniature Ball Bearings: Miniature ball bearings are small-sized bearings with balls as rolling elements, sometimes referred to as instrument bearings or miniature ball bearings. They mainly consist of an outer ring, an inner ring, a retainer, seals, and balls. Miniature bearings are typically used for inner diameters within 10mm, and they come in both inch and metric specifications. They offer low noise, vibration, and friction torque performance. These bearings are widely used in medical equipment, instruments, semiconductor devices, aviation, dental equipment, electronics, and robotics, among other industries.
Deep Groove Ball Bearings: These are the most widely used type of ball bearings. They are characterized by low friction resistance, high speed, and the ability to withstand radial loads, axial loads, and combined loads. Deep groove ball bearings come in single-row and double-row types, and are available in sealed, shielded, and open configurations. They are used in applications such as low-power motors, automotive and tractor gearboxes, and machine tool gearboxes.
Angular Contact Ball Bearings: These bearings can simultaneously withstand radial and axial loads. Their axial load-bearing capacity increases with the contact angle α (15°, 25°, 40°). Angular contact ball bearings come in single-row and double-row types, as well as sealed and open configurations.
Thrust Ball Bearings: Thrust roller bearings are used to bear axial loads primarily and combined axial and radial loads, but the radial load should not exceed 55% of the axial load.
Self-Aligning Ball Bearings: Self-aligning ball bearings are double-row ball bearings that are very suitable for applications where the shaft and bearing housing are not aligned. They are primarily used to withstand radial loads.
Thin-Section Bearings (Kaydon Equivalent): Thin-section bearings have a cross-section that remains constant with increasing inner diameter. AUBEARING manufactures Reali-Slim thin-section bearings and Ultra-Slim thin-section bearings, with inner diameters ranging from 1" to 40" (inch) or 20mm to 360mm (metric), and cross-sections from 3/16" to 1". Their grades range from ABEC1 (P0) to ABEC7 (P4), to meet different customer needs.
6700, 6800, 6900 Thin-Section Bearings: The 16000, 6700, 6800, and 6900 series thin-section deep groove ball bearings are designed to withstand radial loads. They feature low friction coefficients, low vibration noise, and high-speed limits, making them ideal for compact design mechanical equipment.
Needle Roller Bearings: Needle roller bearings are a type of cylindrical roller bearings that have a high load-bearing capacity. They are equipped with slender and long rollers (roller diameter D≤5mm, L/D≥2.5, where L is the roller length).
Crossed Roller Bearings: Crossed roller bearings have cylindrical rollers arranged perpendicularly on V-shaped groove rolling surfaces with separators. Thus, crossed roller bearings can bear radial loads, axial loads, and torque loads in multiple directions.
Tapered Roller Bearings: Tapered roller bearings are separable bearings available in inch and metric series. They can be easily mounted on the shaft journal and bearing housing. Tapered roller bearings are suitable for bearing radial loads, single-direction axial loads, and combined radial and axial loads. The axial load capacity depends on the contact angle α, i.e., the angle of the outer ring raceway. The larger the contact angle, the greater the axial load capacity.
Cylindrical Roller Bearings: Cylindrical roller bearings can be divided into single-row, double-row, and multi-row cylindrical roller bearings based on the number of rolling elements. They can bear substantial radial loads and are suitable for medium to low-speed applications.
Spherical Roller Bearings: Spherical roller bearings have a self-aligning feature, which can compensate for installation errors or shaft deflection leading to the inclination of the inner ring. Spherical roller bearings can bear bidirectional axial forces and high radial forces, particularly suitable for heavy load or vibration applications. Spherical roller bearings are classified into symmetrical and asymmetrical spherical roller bearings based on the shape of the roller cross-section.
Thrust Roller Bearings: Thrust roller bearings can be used to bear axial loads primarily and combined axial and radial actual loads, but the radial load should not exceed 55% of the axial load. They have a low friction coefficient, high-speed capabilities, and self-aligning performance.
Pillow Block Bearings: These are bearing units that combine rolling bearings with bearing housings. The bearing housing is generally cast-formed. They are mainly used to bear radial and axial combined loads, primarily radial loads, and are not suitable for bearing axial loads alone. They are primarily used in agricultural machinery.
Stainless Steel Bearings: Stainless steel bearings are made from stainless steel materials (AISI 440\316\303), particularly suitable for high humidity, strong acid, and strong alkali environments, requiring high corrosion resistance and sealing performance.
Ceramic Bearings: AUBEARING can manufacture both full ceramic bearings and hybrid ceramic bearings. Ceramic materials include zirconia (ZrO2), alumina, silicon nitride (Si3N4), and silicon carbide (Sic). The retainers are made of PTFE, nylon 66, polyether ether ketone, zirconia, silicon nitride, stainless steel, or special aviation aluminum. Ceramic bearings are characterized by anti-magnetic, electrical insulation, wear resistance, corrosion resistance, self-lubricating, high temperature, and low temperature resistance. They are suitable for extreme environments and special working conditions.
