Stepped Insert Body with Cylindrical Machined Insert and Axial Through-Bore External Grooves

Electric motor stator housings, automotive transmission cases, and medical device precision bores use a cylindrical machined insert where external groove width and bore ID together determine whether the insert retains its O-ring at operating pressure and whether the bore aligns the inserted shaft concentrically; groove width outside tolerance allows the O-ring to extrude under pressure, while bore ID deviation shifts the retained component off the housing centreline. Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) turns and mills this aluminium cylindrical machined insert with stepped body, axial through-bore, and external grooves using turning, milling and turning, and internal cylindrical grinding at their just under 2,000 m² Dongguan facility, with groove width, bore ID, and OD concentricity confirmed to match your drawing during in-process inspection. IATF 16949 and ISO 9001 certifications cover automotive, electric motors, aerospace, and OEM manufacturing cylindrical machined insert applications. Supply groove dimensions, bore ID tolerance, OD fit class, and aluminium grade with your enquiry. Key industries: military, automation, and drones.
