Custom Bushings & Sleeves — Steel, Brass & Stainless

What this part is and where it is used

Bushings and sleeves are hollow cylindrical parts with a precise inside and outside diameter, used to guide, support, space or reduce wear between a shaft and a housing. They are machined to your drawing, so the ID, OD, length, wall thickness and material are set by the print. Unlike a threaded fastener, a bushing usually has no thread — it presses or slides into position and lets a shaft turn or move through it.

Buyers order custom bushings and sleeves when a catalog size or material does not fit: a non-standard bore, a flange for axial retention, a split for easier fit, or a bearing alloy such as brass or copper. They are common in pivots, linkages, shafts and mounting blocks.

Types of bushings and sleeves we manufacture

We machine the common forms to print:

• Plain bushings — straight cylindrical sleeves.
• Flanged bushings — a collar on one end for axial location.
• Split sleeves — a slit along the length for easier fit and retention.
• Shouldered and stepped sleeves with custom walls and steps.

Some buyers raise sleeve bolts and sleeve anchors — including stainless sleeve anchors and stainless steel sleeve anchors — in the same conversation. Those are threaded fasteners for structural mounts, while this page covers the plain cylindrical bushing and sleeve itself. For the threaded side, see our custom fasteners pages.

Materials, threads and finishes

Common materials are brass and copper for bearing and wear surfaces, aluminium (6061, 7075) for light weight, stainless steel (303, 304, 316L) for corrosion, carbon and alloy steel (1045, 1215, 4140) for strength, and titanium for weight-critical parts; see our brass and copper parts, stainless steel parts, aluminium parts, steel parts and titanium parts pages.

Most bushings are unthreaded, but a threaded sleeve follows metric or inch references — see our thread standards guide. Finishing runs through our vetted partner network under one quality process: passivation for stainless steel, anodizing for aluminium and black oxide for steel, among others. Wall thickness and concentricity are held to the print, so the bushing presses or slides into its housing the way the drawing intends.

Industries and applications

Bushings and sleeves appear in automotive, aerospace, oil and gas, hydraulic and pneumatic and agriculture assemblies. They guide shafts in pivots, linkages and pumps, while flanged bushings locate parts axially in mounting blocks and machine fixtures.

Why order this part from our factory

We machine bushings and sleeves in our own factory in Qidong City, Jiangsu Province — the bore and outside diameter are cut on our floor, so concentricity comes from one setup. General work is held to ISO 2768-m unless stated on the drawing, with precision features to ±0.01 mm. Orders start from 50 pieces; samples take 5–10 days and production 25–35 days. Monthly capacity runs over 100,000 parts, scheduled flexibly per order. Send a drawing and we return DFM feedback with a quote within 24 hours, then ship with a material certificate (MTR) and pre-shipment photos. WhatsApp us at +86 177 2151 9382 or use the quote form.
