PU Rollers
Heavy-duty polyurethane coated industrial rollers engineered for demanding web handling, metal processing, automated conveying, and printing machinery. Features chemically bonded PU vulcanization to steel, stainless, or aluminum cores.
Types & Configurations of PU Rollers
Heavy-Duty Metal Coil Feed Rollers
Tough 95A Shore A polyurethane covering resisting gouging from sharp steel and aluminum strip edges.
Printing & Varnishing Nip Rollers
Precision ground soft 45A-60A Shore A polyurethane rollers providing uniform ink and coating transfer.
Conveyor Guide & Support Rollers
Flanged or crowned PU rollers maintaining belt alignment under high-speed industrial parcel sorting.
Grooved De-Watering & Squeegee Rollers
Spiral or herringbone grooved polyurethane rollers expelling liquid in textile and tannery lines.
PU Friction Drive & Tension Rollers
High-traction polyurethane compounds delivering maximum torque transmission without slippage.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Cast Polyurethane 70A - 95A | 5x higher abrasion resistance than rubber, high load | Forklift drive wheels, heavy slurry scraper blades |
| Hydrolysis-Resistant PU (Ether) | Resists microbial attack, wet environments & water | Marine guide rollers, wastewater treatment scrapers |
| High-Resilience PU (Ester) | Superior dynamic spring properties, tear strength >60 kN/m | Die-spring blocks, metal-stamping cushions |
| Food-Grade Polyurethane | FDA 21 CFR 177.2600 compliant, oil & fat resistant | Bakery dough rollers, meat processing conveyor scrapers |
| Antistatic PU (ESD) | Surface resistivity 10⁶ - 10⁹ Ω/sq prevents sparking | Automated warehouse AGV wheels, paint-line rollers |
