consists of a honed, double-spiral wiping
element of age-hardened beryllium copper (hardness
Rockwell C 40) surrounded by a synthetic rubber elastomer.
It is manufactured so that the copper element is
distended to the final rod diameter and precision honed
to an inner-diameter tolerance of ±0.0005”. The honing
process guarantees a true circle on the ring inner diameter
in addition to providing a highly polished and knife
sharp edge. The beryllium copper ring polishes the rod
without damage to the rod’s finish.
Equi-Flex Rod Wiper/Scrapers
effectively wipe and
scrape the full 360° circumference of the rod. They
remove road dust, dirt, ice, mud, weldflash, paint and
many other particulates from the rod. They prevent
damage to bearings, seals, packings and rods, thereby
effectively reducing or eliminating contamination
of the fluids in hydraulic systems. Equi-Flex Rod
are found where hydraulic or pneumatic
cylinders are used. They have demonstrated their
effectiveness in fork lifts, resistance welders, off road
machinery, farm equipment, hydraulic presses, foundry
machines and aircraft landing gear.
