JZ253
Tube-shape-Composite material
■ In places where the oil film is difficult to form such as linear motion, free rotation, frequent start and stop, etc., it can still exert superior wear resistance.
■ In the state of no oil supply, under the conditions of high load and low speed operation, it shows a stable low friction coefficient; when used together with lubricating oil, it can be used even in the range of medium and high speed, under high PV value.
■It has excellent drug resistance.
■Low cost; conducive to mass production.
