Flanged Stepped Circular Spacer with Stainless Steel Shaft Collar and Central Through Bore

Bore ID tolerance and collar face perpendicularity to the bore axis are the critical callouts for a stainless steel shaft collar with concentric stepped ring profile; bore undersize prevents the collar from sliding to the locking position on the shaft, while face non-perpendicularity applies bending moment to the shaft at the collar clamping zone. Ningbo Bhin Precise Machinery (established 2009, Ningbo, Zhejiang) turns this stainless steel shaft collar with central through bore and stepped ring using CNC turning, with bore ID, collar face perpendicularity, and ring step height matched to your released dimensions specification. IATF16949 and ISO 9001 certification at Bhin's 4,000 m² of floor space Ningbo facility governs process documentation for robotics, electric motor, and hydropower shaft collar applications. Polishing is available in-house for the stainless collar bore finish. Production supports aerospace, medical equipment, and oil & gas requirements. For pricing, provide bore ID, face perpendicularity, step dimensions, and stainless grade and request an estimate from our Ningbo team from your print.
