The WR® (Wear Resistant) line offers excellent wear and friction properties, along with superior non-galling and non-seizing performance. The WR® material portfolio enables extended MTBR and improved reliability.

Offering extended dry-run performance and exceptional chemical resistance, our WR® materials reduce running clearances by more than 50% in many cases. These reduced clearances minimize recirculation, which maximizes rotor stability (reducing vibration) and overall efficiency.

WR® materials operate in cryogenic temperatures up to 274°C (525°F). WR® materials are typically PEEK with carbon fibers, although our newest offering in the WR® line, WR® 650, is made of PFA with carbon fibers and provides the best overall performance in the portfolio.
