Bidirectional thrust ball bearing/52202/52204/52405/52205/52305/NSK/NTN/Timken/Koyo/NACHI
Product Description
Characteristics of thrust ball bearings:
1. Application scope: Thrust ball bearings are mainly used to bear axial loads in one direction. They are usually used in mechanical equipment with low rotation speeds, such as crane hooks, vertical water pumps, centrifuges, jacks and low-speed reducers.
2. Structural features: The shaft ring, seat ring and rolling elements of the thrust ball bearing are separated and can be assembled and disassembled separately.
Self-lubricating: Thrust ball bearings adopt special materials and lubrication methods, and have good self-lubricating properties.
3. Lifespan and fatigue resistance: The bearing has excellent fatigue life and durability and can maintain long-term operation even under high speed, high load and high unstable load.
4. Reliability: Thrust ball bearings have high axial and radial load-bearing capacity and are suitable for high-speed and high-precision occasions.
5. Adaptability: It can adapt to high temperature, high clutter environment and special working conditions, such as high-speed motors, air compressors, centrifugal fans, machine tool spindles and automobile transmission shafts.
Other types: Thrust ball bearings are available in various types, including flat seat cushion types and aligning spherical seat cushion types, to meet different application needs.
Applications of thrust ball bearings:
Machine tool processing and industrial production: In high-speed, high-load, high-precision, high-reliability situations, such as high-speed motors, air compressors, centrifugal fans, machine tool spindles and automobile transmission shafts, etc.
Automobile industry: widely used in automobile parts such as wheels, transmissions, drive shafts, hydraulic pumps, etc.
Other fields: also include sliding doors, fan motors, lifting and transportation machinery, etc. In these fields, thrust ball bearings help reduce axial clearance, improve transmission efficiency and extend service life.

Thrust bearings are mainly bearings that bear axial force, which is the force in the direction of the shaft. Thrust bearings are also called thrust bearings.
Thrust ball bearing installation method:
The installation operation of thrust ball bearings is relatively simple, but in actual use, errors often occur. For example, the tight and loose rings of the bearing are in the wrong position, causing the bearing to not function properly and the journal to wear. Installing the tight ring on the end face of the stationary part is a wrong assembly; when the shaft diameter is working, the tight ring is driven, causing friction between the tight ring and the end face of the assembly. At the same time, the axial load force during operation will also cause the friction moment to be greater than the inner diameter. The occurrence of mating resistance torque causes the mating surface to be forced to rotate, causing severe wear of the journal.
Therefore, the following points should be paid attention to when installing thrust ball bearings:
1. According to the internal diameter of the bearing, the hole diameter difference between the tightening ring and the loose ring is 0.1-0.3mm.
2. The bearing loose ring is assembled on the end face of the stationary part.
The above are the precautions for the installation of plane thrust ball bearings. The simpler the thing, the more attention you need to pay attention to, so as to avoid the bearing being damaged and affecting the work. When installing thrust bearings, the most important thing is to remember the positions of the loose and tight rings.
