Coated Steel Joint Bushing

Description

Mechanical properties

Characteristic

Using structural alloy steel as matrix steel and machining the oil pockets in the inside holes

QPQ nitriding treatment, superior seizure resistance and fatigue life

Good self-lubricating property beacause of the coating on the surface

 

Application

All kinds of construction machines like excavators, bigger loaders, injection machines and forging machines etc.
