PEEK Roller For Selvedge Uncurler
Replacement PEEK roller for roller-type selvedge uncurlers on stenters, pre-shrinking and printing machines.
Product Overview
A selvedge uncurler opens and flattens the edges of fabric before dyeing, finishing or printing. This is the rotating PEEK roller that does the work in roller-type units, supplied as a replacement wear part.
Roller-type uncurlers come in two-finger, three-finger and four-finger designs, suited to different fabric weights and line speeds. We supply rollers in black, white and brown PEEK to match the unit you already run.
Key Benefits
- PEEK body is self-lubricating, so the roller turns freely without added grease on the cloth line
- Replaces a worn roller without changing the whole uncurler assembly
- Used on stenters, pre-shrinking machines and printing machines
- Available in black, white and brown to match existing hardware
Who It Is For
- Mills running roller-type uncurlers who need the wear part, not a new unit
- Maintenance stores stocking rollers for stenter, sanforizer and print lines
- Engineers converting a metal roller to PEEK for longer life
Problems It Solves
- A seized or worn roller dragging on the selvedge instead of rolling with it
- Fabric curling or edge damage during high-speed operation
- Buying a complete uncurler when only the roller has worn
Application Scenarios
- High-speed operation where a seized roller starts dragging on the edge
- Pre-shrinking lines where the edge has to be opened before compacting
- Printing machines where a curled edge would show as a registration fault
Technical Features
- PEEK body, self-lubricating and wear-resistant
- Supplied in black, white and brown
- Fits roller-type uncurler designs in two, three and four finger configurations
- Used on stenters, pre-shrinking machines and printing machines

Certifications. We make no certification claim for this part. The original company statement is that products comply with international quality standards; no certificate is named and none is asserted here. Ask us directly if your procurement process requires documentation.
Comparison With Other Options
Against a metal roller, PEEK is self-lubricating and kinder to the cloth, and it does not need the grease that would otherwise find its way onto the fabric edge. Against a pneumatic spreader, the roller type is mechanical: cheaper and simpler, but it does touch the cloth.
Use Guide
Measure the worn roller before ordering, including bore and shoulder positions
Check the shaft and bearing seat while the roller is off, because a worn shaft kills a new roller quickly
Fit without forcing; PEEK is tough but should not be hammered onto a shaft
Turn the roller by hand after fitting to confirm it spins freely
Replace a whole bank together so all rollers share the same diameter
FAQ
Questions About PEEK Roller For Selvedge Uncurler
Why PEEK rather than metal?
PEEK is self-lubricating and wear resistant, so the roller keeps turning freely without grease on the fabric line, and it is gentler on the selvedge.
Which machines is it used on?
Stenters, pre-shrinking machines and printing machines, wherever a roller-type selvedge uncurler is fitted.
Can you make it to my size?
Yes. Send the worn roller or a dimensioned drawing and we turn to match.
What colours do you supply?
Black, white and brown. The colour follows the PEEK grade and the set you already run.
Mechanical or pneumatic type, which do I need?
Mechanical uses physical contact and suits most work. Pneumatic is contactless and is the choice for delicate articles such as denim edges that mark easily.
How fast can you deliver?
Standard sizes ship within 7 days. Turned-to-drawing rollers are confirmed at quotation.
