Hardened steel bushing HSB 35x45x45

HSB type sliding bushings, or hardened bushings at a temperature of 840°C, are made from high-quality carbon structural steel, compliant with Japanese standard S45C, American 1045, and German C45. They have lubrication grooves both inside and outside. The GB/T699-1999 standard states 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.
