Cemented Carbide Shaft Component with Precision Stepped Pin and Flange Head

Step diameter tolerance and flange face perpendicularity to the pin axis govern fit for a cemented carbide precision stepped pin; step diameter outside tolerance prevents the pin from being pressed to its design seating depth, while flange face runout causes the retained component to tilt off-axis under tightening force and introduces a bending moment at the shank root that can fracture the brittle carbide. Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) grinds this cemented carbide precision stepped pin with flange head using external cylindrical grinding, internal cylindrical grinding, and surface grinding at their upwards of 2,000 m² Dongguan facility, with step diameter, flange face perpendicularity, and shank OD cross-checked with your print at first article sign-off. IATF 16949 and ISO 9001 certifications govern traceability for aerospace, automotive, medical equipment, and OEM manufacturing precision stepped pin applications. Attach your print specifying step diameter tolerance, flange specification, shank OD, and carbide grade. For a grinding price estimate from our dongguan team. Active sectors include military, automation, and drones.
