Hardened steel bushing HSB 65x80x75

HSB type sliding bushes, which are hardened at a temperature of 840°C, are made from high-quality carbon structural steel, compliant with the Japanese standard S45C, the American 1045, and the German C45. They have lubrication grooves both 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 are characterized by higher strength and resistance to deformation than ordinary steel.
