1. It can be a long time in the oil-free working conditions.
2.Maintenance-free, long life
3.JDB inlaid solid self-lubricating bearings, combined with the wear resistance of copper alloys and self lubricating properties of solid lubricants, so that in the course without refueling maintenance. Products are widely used in high load, intermittent or oscillating motion, such as the steam locomotive production lines, turbines, reservoirs work / accidents doors, plastic machinery. Depending on conditions, can provide various types of copper alloy.
