JLB-G Joint bearing low friction coefficient self-lubricating bearing material as a sliding friction, in operation without maintenance. Suitable for the following applications: Requirements bearing has a long life without the need for maintenance, or working conditions (such as insufficient lubrication or completely without lubrication) does not allow the use of steel-on-steel bearings, self-lubricating bearings are mainly used constant heavy charge case, the outer steel base heat treatment, the inner ring of high-strength copper alloys and inlaid solid lubricant, features: self-lubricating characteristics, carrying capacity, good wear resistance, etc. ......
