Hardened steel bushing HSB 100x115x110

HSB type sliding bushings, i.e., bushings hardened at a temperature of 840°C, are made of high-quality carbon structural steel, compliant with Japanese standard S45C, American 1045, and German C45. They have lubrication grooves inside as well as outside. The GB/T699-1999 standard specifies that the tensile strength of steel 45 is 600 MPa and the yield strength is 355 MPa. Hardness level: HRC 60. The bearings are characterized by higher strength and resistance to deformation than ordinary steel.
