Maintenance-free bearings generally refers to the self-lubricating bearings, suitable for self-lubricating bearing in the low-load, lubrication difficult occasions!

From installation to failure without maintenance can be long copper manufacturers stable working period of rolling bearings.

The technical principle:

By optimizing the geometry and surface finish of the bearing channel, redesigning the maintenance-free bearing retainer, the use of high-performance bearing steel in combination with a unique heat treatment process, improved ball accuracy, etc., greatly reduces the grease Consumption; optimized sealing structure easier for grease storage and lubricating oil to the channel of the precipitation, with life-full grease filling, to provide more lasting lubrication of the rotation. A number of process improvements and applications to achieve a huge increase in bearing performance, bearing life cycle from maintenance on a regular basis.
