Custom Precision Bushings, Sleeves and Spacers

Bushing and sleeve terminology can hide different functions. A locating bushing, sliding bearing, press-fit adapter, shaft-protection sleeve and spacing sleeve require different material, surface, fit and inspection decisions.

Identify the Functional Pair

Provide the mating shaft or pin, housing bore and installation state. A free-state measurement may not predict a thin-wall or press-fit component after installation. Sliding interfaces also require load, motion, lubrication and environmental information.

Parts Worth Reviewing

Small concentric sleeves, spacers and adapters made from bar-shaped stock
Multiple internal and external diameters with shoulders or end features
Threaded, grooved, slotted or cross-drilled sleeves
Repeat parts with drawing-controlled mating interfaces

Conditions Requiring Additional Review

Thin walls vulnerable to clamping or installation distortion
Critical bores requiring grinding, honing, lapping or polishing
Self-lubricating composite, wrapped or sintered bearing constructions
Coating thickness that changes final internal or external fits
Performance claims that depend on the complete tribological system

RFQ Inputs
