Bearings are one of the most widely used parts in our modern industry, as long as the products and equipment related to the transmission device basically use bearings. The overall technical level of the bearing industry has achieved remarkable results in recent years. So what is maintenance-free bearings ? What are its characteristics?

Maintenance-free bearings refer to rolling bearings that can work stably for a long time without maintenance from installation to failure. It has outstanding performance of maintenance-free, high performance, long life, more environmentally friendly, reliable and durable. Experts have greatly reduced the consumption of grease by optimizing the geometry and surface finish of the bearing channel, redesigning the retainer, combining the use of high-performance bearing steel with a unique heat treatment process, and improving the accuracy of the steel ball. ; Optimized sealing structure makes it easier to store grease and precipitation of lubricating oil to the channel. With the filling of full-life grease, it provides longer-lasting lubrication for rotation. The improvement and application of a number of processes have achieved a huge improvement in bearing performance, eliminating the need for regular maintenance during the bearing life cycle.

In addition to the maintenance-free bearings, the universal joint cross is also a very useful bearing. The durability and application range of the universal joint are very wide, and it is easy to use and easy to operate.
