High Precision Custom Meta CNC Machining Parts Details
Custom Precision CNC Turned Bushing
This precision CNC turned bushing (also known as bearing sleeve or wear-resistant locating sleeve) is a non-standard custom machined rotational component widely used in hydraulic & pneumatic systems, mechanical transmissions, precision jigs, fluid equipment, and automation devices – where precise guidance, concentric locating, and wear-resistant support are essential.
Machined from solid bar stock via CNC turning, this one-piece sleeve structure delivers excellent rigidity and stable geometric accuracy. The precision inner bore serves as the core functional surface, providing guidance, concentric locating, and wear support for shafts, valve spools, or guide rods – with tight requirements for roundness, concentricity, and surface finish. The external annular grooves serve multiple purposes: O-ring seal grooves for hydraulic/pneumatic sealing, retaining ring grooves for axial positioning, and relief grooves for machining. The end locating step provides an axial mounting reference for precise assembly positioning.
We offer full customisation: groove profiles, dimensions, materials, and tolerances are all machined exactly to your drawings. MOQ starts at 1 piece, with rapid prototyping for urgent projects and free DFM feedback included with every quote. We also manufacture identical or similar custom bushings, sleeves, and precision rotational components to your drawings.

4. Quality Assurance – ISO 9001:2015 Certified
Free DFM Analysis – We don't just machine your parts; we optimize them. For this turned bushing, our DFM review focuses on bore roundness control, groove geometry, tool access, surface finish optimization, and tolerance stack-up – ensuring manufacturability without sacrificing performance.
Strict Inspection – All critical dimensions are verified in our temperature-controlled metrology lab using CMM, optical measurement, surface roughness testing, air gauging for bore accuracy, and First Article Inspection (FAI) protocols. Full FAI reports are provided with all first-batch orders.
Full Traceability – Inspection reports, material certifications, and dimensional records accompany every shipment.
