Flanged hardened steel bushes, with oil grooves, oil ring and oil pockets, E470 (EN10297) steel

HSB series
Hardened Steel Bushings (Metric Size)

Flanged hardened steel bushes, with oil grooves,
oil ring and oil pockets, E470 (EN10297) steel

SinoBronze hardened steel bushings are backed with steel, and it`s inner surface has many spiral oil grooves, oil rings, oil holes, round and elliptical oil sockets. After quenched and tempered, the surface roughness and wear-resistant has been improved.

This type of product is used in engineering machinery field and applications that demand high wear resistance without cracking under heavy load.

Material Features
• SinoBronze hardened steel bearings deliver greater wear resistance while the interior remains ductile and resistant to cracking; • Appropriate for heavy equipment, hydraulic cushioning and rotational applications; • Special alloy contains manganese and vanadium for improved strength and toughness, increased hardening rate and higher wear resistance.
