Key Advantages
- Drops into Epiroc RD18U and RD22U carriers without modification – same OD, ID, and thickness as the OEM drawing.
- Machined from alloy steel, then heat-treated to a hardness that resists deformation even when the guide starts to wear.
- We ran batches on active mine sites in western Australia: average service life was within 8% of the Epiroc-branded ring, at less than half the price.
- Chamfered edges prevent the ring from digging into the piston housing during assembly, which cuts install time and reduces the risk of nicked seals.
- Every ring gets a dimensional check before shipping – no guesswork, no “close enough” tolerances.
