WR tight-tolerance rod composite wear rings, when combined
with the WP profile, complete the premier cylinder bearing system.
Recommended for light- to heavy-duty hydraulic applications, they are
available in standard sizes from 7/8” up to 7” rod diameters (larger sizes
upon request). WRs feature chamfered corners on the O.D. and are
designed to snap open during assembly to hold tight against the head
gland, eliminating rod interference and simplifying installation.
