Thrust bearing in China with best quality
Thrust Bearing
What is thrust bearing
Thrust bearing is a special bearing specially used to bear axial force, that is, the bearing with the force of the vertical direction of the shaft.

Failure and avoid methods
Here we list the possible causes and solutions of bearing failure, so that you can quickly solve the problem.
ZWA thrust bearing
Thrust bearings are divided into thrust ball bearings and thrust roller bearings.
Thrust ball bearings include thrust ball bearings and thrust angular contact ball bearings. A raceway ring with a raceway gasket and a ball and a cage assembly is called a raceway ring with a shaft, and a raceway ring with a housing is called a seat ring. Two-way bearings match the center ring with the shaft. Unidirectional bearing can bear unidirectional axial load, and bidirectional bearing can bear bidirectional axial load. The bearing with spherical mounting surface of the seat ring has self-aligning performance, which can reduce the influence of installation error. This kind of bearing is mainly used in automobile steering mechanism, machine tool spindle.
Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust spherical roller bearings, thrust tapered roller bearings, thrust needle roller bearings. Thrust cylindrical roller bearings are mainly used in oil drilling rigs, iron and steel machinery. This kind of thrust spherical roller bearing is mainly used in hydraulic generator, vertical motor, ship propeller shaft, tower crane, extruder and so on. Tapered thrust roller bearing – most commonly used in automotive applications. They can support greater thrust loads than the ball type due to the larger contact area. They are designed to accommodate combined loads, i.e., simultaneously acting radial and axial loads.
- Thrust ball bearing – used in low thrust applications where there is little axial load. They are available in two designs: single direction and double direction.
- Cylindrical thrust roller bearing – give good carrying capacity.
- Tapered thrust roller bearing – most commonly used in automotive applications. They can support greater thrust loads than the ball type due to the larger contact area. They are designed to accommodate combined loads, i.e., simultaneously acting radial and axial loads.
- Spherical thrust roller bearing – Spherical roller thrust bearings offer the highest load rating density of all thrust bearings.
Failure and avoid methods
| Running condition | Supposed reasons | Countermeasure | |
|---|---|---|---|
| Noise | Metal noise | Abnormal load | Correct fit and bearing clearance, adjust preload. |
| Bad installation | Improve installation method and accuracy. | ||
| Insufficient lubricant | Add lubricant and choose appropriate lubricant. | ||
| The rotating parts touch each other | Modify the contact part of the labyrinth seal. | ||
| Regular noise | Indentation, rust, or scarring caused by foreign matter | Replace the bearing, clean the relevant parts, improve the sealing device, and use a clean lubricant. | |
| Brinell indentation | Replace the bearing using the correct mounting method. | ||
| Fatigue spalling of raceway surface | Replace the bearing. | ||
| Irregular noise | Clearance is too large | Modify fit clearance,adjust preload. | |
| Foreign invasion | Replace bearing, clean related parts, improve sealing device, use clean lubricant. | ||
| Peeling off | Replace the bearing. | ||
| Abnormal warming | Excessive lubricant | Reduce the amount of lubricant, choose a harder grease. | |
| Insufficient lubricant and unsuitable brand | Add lubricant and choose appropriate lubricant. | ||
| Abnormal load | Modify fit clearance, adjust preload. | ||
| Bad installation | Improve the installation method, improve the installation accuracy. | ||
| Mating surface creep, sealing device friction | Replace the bearing, modify the fit, improve the sealing mechanism, modify the dimensional accuracy of the shaft and bearing seat. | ||
| High vibration (axis swing) | Brinell indentation | Replace the bearing using the correct mounting method. | |
| Peeling off | Replace the bearing. | ||
| Bad installation | Correct the verticality of shaft, bearing shoulder and bearing end face. | ||
| Foreign invasion | Replace bearings, clean parts and improve sealing devices. | ||
| Serious leakage and discoloration of lubricant | Excessive lubricant, foreign matter, abrasive chip invasion | Select lubricant or replace the bearing and clean the housing. | |
