CNC Machined Piston Shaft Pin Stainless Steel ANSI 431 Polishing 6 X 50 mm
CNC Machined Piston Shaft Pin Stainless Steel ANSI 431 Polishing 6 X 50 mm
Stainless steel piston shaft pin machined parts are made from harden ANSI 431 material , multiple stepped sections with different diameters , a groove slot in middle of piston shaft pin and cut threads so that accelerate oil running , one end is shaft for leading purpose during installation .
