Hardened steel bushing HSB 36x45x40

HSB type sliding bushings, which are 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 and 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 have higher strength and resistance to deformation than ordinary steel.
