Selection for the bearing retainer
For the engineering plastic shelf, the performance of each manufacturer is slightly different, but generally similar. The bearing retainer light in weight and is suitable for high speed applications. And the failure mode of the cage is not sudden breaking, so it is more suitable for some situations where sudden stop is not allowed. But for mining machinery, this kind of cage due to security concerns are not suitable for use, damage because it is not sudden, but as the temperature increased to a certain degree, after completely broken, it could be dangerous for explosive occasions. This kind of cage temperature limitation at the same time, it is commonly - 40 ~ 120 ℃ :
There is little resistance to the brass bearing retainer, but it is not suitable for ammonia. Generally small bearings do not use copper holders.
There are no restrictions on steel cage, but steel cage is not used for large bearings。
