Stepped Alignment Pin with Cylindrical Locating Pin and Multi-Spline End

Pin OD tolerance and spline profile accuracy drive the acceptance criteria for a carbon steel cylindrical locating pin with multi-spline end; pin OD outside tolerance produces a loose or interference fit in the mating bush that either allows lateral play or requires force to seat, while spline profile error prevents the pin from engaging its drive socket at the correct angular position. Suzhou Dazhi Intelligent Manufacturing Technology (Suzhou, Jiangsu) turns and grinds this carbon steel cylindrical locating pin with stepped body and multi-spline end using turning, external cylindrical grinding, and wire EDM at their facility (roughly 4,000 m²), with pin OD, spline profile, and step concentricity cross-checked with your print at initial sample sign-off. Dazhi's Suzhou facility specialises in non-standard automation parts, aerospace components, and medical parts for automation, robotics, medical equipment, and general industry applications.
