Roller anatomy
A roller is four parts working together
When a roller fails, it’s usually one of these. Knowing which one tells us what the replacement needs.
-
Live shaft
The shaft turns with the roller, on bearings in the frame.
-
Dead shaft
The shaft is fixed in the frame; the roller spins on bearings inside it.
| Part | Tell us | Common failure |
|---|---|---|
| 01 Shell | Outside diameter, wall or inside diameter, face length and profile. | Wears through, flat-spots or starts marking product. |
| 02 Bore and bearing seat | The bearing or bushing size, and how it’s held in. | The seat wears and the bearing spins in the bore. |
| 03 Bearing or bushing | Type and size, sealed or open, or a plain bushing. | Grit gets in and it seizes. The stopped roller then drags and damages the belt. |
| 04 Shaft and ends | Live or dead shaft, diameter, end shape and frame width. | Rusts, or bends over a long span. |
Shell only or complete roller? We machine the roller and can assemble it with its bearings or bushings, and machine aluminum, brass or bronze parts where the design calls for them. Tell us what you need. Assembly service

Plastics for rollers
Common choices, and why
- UHMW Absorbs impact, low friction and gentle on product.
- Nylon Strength and wear resistance for loaded or drive rollers.
- Acetal Dimensionally stable with low moisture uptake, good in wet service.
- HDPE An economical, chemical-resistant shell.
- PTFE Non-stick, for sticky products and harsh chemicals.
- Detectable acetal For lines with metal or X-ray inspection.
- Static-dissipative grades For handling electronics and other static-sensitive product.

Switching from steel?
Plastic or steel rollers
Plastic suits many conveyor rollers, but not every one. Load, span, speed and heat all matter.
Where plastic helps
- No rust in washdown
- Plastic doesn’t corrode in wet, washdown or chemical service.
- Lighter
- Easier to handle, and less weight for the frame and bearings to carry.
- Gentler on product
- A softer contact surface that’s less likely to mark product.
- Quieter
- Plastic rollers generally run quieter than steel.
- Plastic bushings
- Self-lubricating bushings can replace greased bearings in some rollers.
Machined in Aurora
How your rollers 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, then milled
CNC turned so the roller runs true, with sprocket teeth, grooves and flats milled where needed.
CNC turning -
Bored to your bearing
Bores and bearing seats machined to the bearing, bushing or shaft you use.
-
One roller to production
A single replacement, a prototype or recurring runs, shell only or assembled.

Plastic roller FAQs

It can help. A softer contact surface is gentler on product, but marking also depends on load, speed, contamination and the product itself. Tell us what’s being marked and how.
Your design sets the span, wall and load, and we machine the roller to your drawing. Include the load and span with your request so we can suggest suitable plastics.
Yes. Detectable acetal is a common choice for rollers on lines with metal or X-ray inspection. Metal- and X-ray-detectable grades work with different systems, so tell us which your line uses.
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 bearing bore, with your quote.
Yes. Specifications and CAD files are kept for future orders, and reorders use a shorter form.
Timing depends on the roller, plastic and quantity, and comes with your quote. For an emergency breakdown, ask about our expedited service.
