WR tight-tolerance rod 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.
