Thrust ball bearings

Features of double-direction thrust ball bearings

The bidirectional thrust ball bearing is characterized in that it can bear the bidirectional axial load and act as a bidirectional axial positioning. Still, it must not bear any radial load. The minimum load of this bearing is to obtain a good running effect, especially at high speed or high acceleration, or in the working environment where the load direction changes rapidly, the inertial force of the ball and cage and the friction in the lubricant will affect the bearing Detrimental to the rolling of the bearing, there may be a sliding movement between the ball and the raceway that is damaging to the bearing. Higher minimum loads may be required at low-temperature start-ups or with high lubricant viscosity. The weight supported by the bearing, plus external forces, especially in the case of vertical shafts, usually exceeds the required minimum load, so preload must be applied, such as using a spring.

• The structure of the Double-direction thrust ball bearing
  

• Double-direction thrust ball bearings consist of a shaft washer, two seat rings, and two steel ball cage assemblies. The bearing is separable; each part can be installed independently.

• 
  

• Such bearings include double-direction thrust ball bearings - with self-aligning races. This type of bearing can be used with self-aligning seat washers to compensate for angular errors between the housing and shaft bearing surface. Double-direction thrust ball bearing with self-aligning race.

• Application of Double-direction thrust ball bearings

• Double-direction thrust ball bearings are widely used, including but not limited to the following fields:

• 
  

• Automobiles: Used in parts that need to bear axial loads, such as steering pins of automobiles and machine tool spindles.

• Machinery: used in heavy machinery, printing machinery, textile machinery, lifting machinery, petrochemical machinery, and other fields.

• Power facilities such as hydroelectric power stations, thermal power stations, and nuclear power stations.

• Medical equipment, optical instruments, and other precision equipment.

• Other occasions must bear bidirectional axial loads, such as satellites, rockets, etc.

• 
  

• It should be noted that during the use of the bidirectional thrust ball bearing, it must be ensured that it can bear bidirectional axial load simultaneously. Otherwise, the bearing may be damaged. In addition, according to different application scenarios, different types of double-direction thrust ball bearings can be selected, such as self-aligning spherical seat cushions or spherical seat types.
