Needle roller cylindrical roller or pin
The core component of needle roller bearings and roller bearings - rolling bodies
needle roller and pin, usually bearing steel wire as material, by quenching precision grinding process, as needle roller bearings and roller bearings, the core components - rolling bodies, requiring high precision, high stability.
we provide all kinds of needle size, specifications, materials made of bearing steel, hardness HRC60 ~ 64, surface roughness Ra is not greater than 0.2. The size range of cylindrical roller: Dw:3 ~ 30, Lw:5 ~ 50; material made of GCr15 steel (bearing steel manufacturing).
1. high hardness
2. high accuracy
3. widely used
used for fasten (wood, tiles, furniture, shoe soles, uppers mold and components) or mend. Pins play an important role in the connection of mechanical parts. According to the shape and function of the different, can be divided into: cotter pin, taper pin, cylindrical pin, pin groove etc.
