- Family owned in Aurora since 1986
- Expedited service for breakdowns
Types of bushing
A sleeve that stays in its housing
The housing stays on the machine and only the sleeve is replaced. Find the shape closest to yours.
- DIAGRAM: plain sleeve bushing, section view
Plain sleeve
A straight cylinder pressed into the housing, with the shaft running in its bore.
- DIAGRAM: flanged bushing, section view
Flanged
A flange locates it in the housing. Designed for it, the flange can also take an end load.
- DIAGRAM: shoulder bushing, section view
Shoulder
An outside step that locates it in the housing. It doesn’t necessarily carry thrust.
- DIAGRAM: seal bushing, section view
Seal bushing
Carries or sits beside a seal, often with O-ring grooves. We can fit the O-rings.
Split bushings are available too, for fitting without pulling the shaft.
Getting the fit right
Free bore vs installed bore
-
Grips the housing
The outside is sized slightly larger than the housing bore so it holds in place.
-
Bore closes in
Pressing it in squeezes the bore a little smaller.
-
Clearance is what counts
The running clearance to the shaft once installed is what decides how it runs.
Tell us whether your drawing gives the free bore or the installed bore, plus the housing bore and the shaft size. We’ll quote to the right one.
What defines a bushing
Housing, bushing and shaft
A bushing sits between the housing and the shaft, so we machine it to fit both.

Plastics for bushings
Common choices, and why
- PTFE Very low friction and broad chemical resistance. Soft, and can creep under load.
- Acetal Stiff and dimensionally stable, so the bore holds its size.
- Nylon Strong and wear-resistant. It takes on moisture, which we allow for in the bore.
- Oil-filled nylon Added lubricity for running dry.
- UHMW For wet, lighter-duty service.
- PEEK For heat and harsh chemicals.
- Detectable grades Metal- and X-ray-detectable plastics, for lines with inspection systems.
We’ll suggest suitable plastics for your bushings. These are the common ones; we machine most engineering plastics.

Plastic or bronze bushings
We machine bronze too, so the choice comes down to the duty. Here’s an honest guide. Replacing metal with plastic
Where plastic helps
- Can run dry
- In suitable duty, with no grease to wash out or contaminate product.
- No corrosion
- Unaffected by water and washdown.
- Chemical resistance
- Many plastics handle chemicals that attack bronze.
- Quiet
- No metal-on-metal at the bore.
- Lighter
- Easier to handle and fit.

How your bushings are made
±0.002"–
±0.005"
On critical dimensions, depending on the plastic. Specs and CAD files are kept, so a reorder matches the last batch.
-
Turned concentric
Outside and bore turned together on CNC turning centers, so they stay concentric.

Flanges, shoulders and grooves
Every step, groove and split machined to your drawing or old bushing.
-
Seals fitted, ready to install
Seal bushings delivered with their O-rings fitted, so there’s no second supplier.

Yes. Teflon is a brand name for PTFE, which comes in virgin and filled grades that behave differently. Tell us exactly what your drawing or old order says, and how the bushing runs.
Only if it’s designed to. Many shoulders just locate the bushing in the housing. If yours takes an end load, tell us the load and what it runs against.
Yes. Specifications and CAD files are kept for future orders, and reorders use a shorter form. Give us the part number or the last order.
We hold ±0.002" to ±0.005" on critical dimensions, depending on the plastic. We review your drawing and confirm the critical dimensions, such as the bore and outside diameter, with your quote.
Timing depends on the bushing, material and quantity, and comes with your quote. For an emergency breakdown, ask about our expedited service.
