Open-Ended Sleeve Component with Cylindrical Bearing Sleeve and Internal Fine Axial Ribs

Robotics joint assemblies, pump shaft support bearings, and precision actuator guides use a cylindrical bearing sleeve where bore ID concentricity and internal fine axial rib profile together determine the lubricant film distribution and running clearance with the mating shaft. Ningbo Bhin Precise Machinery (established 2009, Ningbo, Zhejiang) turns this stainless steel open-ended cylindrical bearing sleeve with internal fine axial ribs using CNC turning and milling, with bore ID concentricity, rib profile, and OD controlled to your print callouts. IATF16949 and ISO 9001 certification at Bhin's Ningbo facility (about 4,000 m²) governs production traceability for robotics, oil & gas, and pump & compressor bearing sleeve applications. Polishing is available in-house for bore surface finish preparation, serving aerospace, medical equipment, and oil & gas applications. To quote, we need your drawing showing bore ID, rib profile, OD, and stainless grade. For a cost estimate from our ningbo production team.
