The square hole relubrication bearing series is a bearing with a special structure and a square hole that can accept the diameter of the shaft. This kind of bearing has a spherical raceway and a deep groove raceway, which can effectively reduce friction and wear and increase the service life of the bearing. In addition, this kind of bearing can be re-lubricated, that is, lubricating oil can be added during use to maintain the lubrication state of the bearing and improve the performance and life of the bearing.


The main advantages of the square hole relubricated bearing range include:


1. Compact structure, easy to install, and can be adapted to various application scenarios.

2. The combination of spherical raceways and deep groove raceways can effectively reduce friction and wear and increase the service life of the bearings.

3. It can be relubricated to maintain the lubrication state of the bearing and improve the performance and life of the bearing.

4. Suitable for harsh environments such as high speed and high temperature, and has high load-bearing capacity and stability.


Square hole relubricating bearing series are used in many fields, such as agricultural machinery, chemical machinery, mining machinery, machine tools, etc. It has a wide range of applications, long service life and low maintenance costs.
