CNC Machined Bushings, Sleeves & Spacers
Bushings, sleeves, spacers, collars, and ring-shaped parts are suitable for CNC turning when inner diameter, outer diameter, length, groove, and face requirements are clearly defined.
Typical Applications
- Bearing sleeves, spacer sleeves, collars, bushings, tube inserts, and precision rings
- Steel, stainless steel, brass, bronze, aluminum, and engineering plastic parts
- Parts requiring deburring, plating, passivation, or inspection before assembly
RFQ Notes
For sleeve and bushing RFQs, include ID/OD tolerances, wall thickness, face flatness, chamfer requirements, and whether the part must fit with a shaft, bearing, or housing.
Recommended RFQ Files
- PDF drawing with tolerances and surface finish notes
- STEP/STP or other 3D model for complex geometry
- Material grade, quantity, finishing requirements, and target delivery date
Bushings and Sleeves: ID / OD and Length Control Matter
Sleeves, bushings, collars, and spacers are usually judged by bore size, outside diameter, length, groove position, and burr condition.
Tight ID / OD fit or thin-wall geometry requires review before quotation.
Buyer Checks
- Confirm inside diameter, outside diameter, and fit tolerance.
- Mark groove width, step position, chamfer, and wall thickness.
- State whether the bore is used for sliding, bearing, sealing, or spacing.
RFQ Details to Send
- Send material, quantity, drawing revision, and critical dimensions.
- Add surface roughness or bore finish notes when relevant.
- Ask for inspection reporting if critical fit dimensions are required.
