Kadant Johnson WRB2N

The WR rotary joint is designed for high-speed water, oil, and air applications. Its two widely spaced ball bearings are protected from external contaminants and condensation using two captured o-rings. The balanced seal minimizes seal loading and increases seal life while providing a uniform, full-flow design. The WR is capable of limited dry running and features a 100% pure-molded carbon graphite seal and carbide counterseat. The WR is available in sizes from 3/8 to 1-1/2 and is rated up to 232 C (450 F), 14 bar (200 psig), and 4,000 RPM.
