Customized Aluminum Grooved Bushing Silver Oxidation 30 X 60 X 20
mm
Carbon steel grooved bushing has several grooved slots on the side
surface for discharging sundries during operation , this design
helps grooved bushing to reduce friction for a longer service .
Normally , grooved bushing is a hollow hole with very small
roughness in the centre for operation of a shaft pin .
Material
Carbon steel with harden treatment
Finish
Zinc plated and free chrome

as medium tensile strength .
Features
Slotted surface design
Hard material
Durable corrosion
Low cost
Customized assorted sizes
Long service
In order to meet different applications for parts , carbon steel
grooved bushings are plated in more finish as following
Zinc
The most popular plating for the most products , making parts are
bright and smooth and resistant corrosion
Nickel
The film thickness is 1～3μm , it improves brightness and wear
resistance .
Polishing
Reduce roughness of parts and improve brightness .
Tin
With film thickness 0.13～1.27μm , tin finish with bright surface
and good ductility ,corrosion resistance ,lower melting point
,eco-friendly features .
