Precision Turned Bushing

The fit clearance of a bushing decides how the assembly feels. Too loose and it rattles, too tight and it will not go in — it comes down to stable ID and OD control.

Key control

ID and OD are finished in one clamping to hold concentricity. Batch parts are checked with plug and ring gauges, and critical dimensions are confirmed on a CMM.

Material

Light-load and thermal parts use 6061-T6 aluminum; wear or corrosion duty calls for stainless steel or hard-anodized aluminum.

Process notes

Bar stock cutting, CNC turning with single clamping for ID and OD, boring, deburring, surface finishing, gauge check plus CMM sampling.

Applications

Drive bushings, guide sleeves, coupling sleeves, sensor sleeves.
