There are significant differences between composite bearings and rolling bearings, so they cannot be used interchangeably.


1. Rolling bearings are often much more expensive than composite bearings due to their complex multi-component design, precision structure and precise installation.


2. Rolling bearings are more suitable for applications requiring precise shaft position and/or very low friction.


3. The compound bearing, due to its larger contact area and adaptability, can provide higher load bearing capacity and resistance to high impact loads and concentrated end loads.


4. Composite bearings make up for the misalignment better than some rolling bearings to reduce the impact of concentrated loads at the ends.


5. The compound bearing adopts ultra-thin single-piece design, which can reduce the size of the housing, greatly saving space and reducing weight.


6. The compound bearing is more resistant to reciprocating motion, which can extend the life of the bearing.




7. The composite bearing will not be subject to the wear and tear caused by the sliding of the rolling element when running under high speed and under low load, and has excellent damping performance.


8. Compared with rolling bearings, composite bearings do not contain moving parts inside, so the operation is quieter, and the speed is almost unlimited under a properly lubricated system.


9. The compound bearing is simple to install, only requires machining the shell, and it will hardly cause damage to the accessories compared with the rolling bearing.


10. Non-metal composite bearings have stronger corrosion resistance than standard rolling bearings.


11. The compound bearing can be operated dry without the cost of additional lubricant system, lubricant and equipment downtime during maintenance.


12. The composite bearing can run dry under high temperature and in the presence of pollutants.
