It can be seen literally that maintenance-free bearings do not require maintenance, or require very little maintenance.
Maintenance-free is generally for self-lubricating bearings, you do not need to add oil, you do not need to maintain it during the service cycle. Maintenance-free bearings refer to rolling bearings that can work stably for a long time without maintenance from installation to fail.
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, the consumption of grease is greatly reduced; The optimized sealing structure makes it easier to store the grease and the lubricating oil to the channel, and with the filling of the full-life grease, it provides longer-lasting lubrication for the rotation. The improvement and application of several processes have achieved a huge improvement in bearing performance, eliminating the need for regular maintenance during the life cycle of the bearing.
