Bushes are made from en 31/cw 1/ OHNS/ SEA 52100/ aisi 01 quality deep hardenable steel. Concentricity of bush id and OD is kept within 0. 01 mm for smaller bushes up to 10 mm id, 0. 02 mm for medium bushes up to 25 mm od and within 0. 03 mm for bushes over 35 mm id. Bushes are hardened to 60-62 hrc. Entry chamfer in od and entry chamfer/radius in id is given as per customers requirements. Two way undercut in collar back face is given to ensure collar back face perpendicularity. Collar thickness can be controlled up to 0. 01 mm as per customers’ requirements. Pins are made from deep hardenable / case hardenable steels depending on the nature of use. Where heavy machining stress is expected, case hardening variety is used and case depth is decided as per use. For both deep hardening steel and case hardening steels, surface hardness is kept in the range of 60-62 hrc.
