OEM 3201195127 STOP RING HUATAI ROCK DRILLING RIGS RD18U RD22U EPIROC 3201 1951 27

Stop ring that takes a beating so your drill string doesn't

The 3201195127 stop ring keeps your Epiroc RD18U or RD22U running when hammering through hard rock. It’s the same part that sits inside the front guide, handling shock after shock without mushrooming or cracking early. HUATAI builds this ring to OE dimensions—drop-in fit, no rework, no surprises. If you’re tired of rings that deform and chew up rod shanks, this one changes the math. Made from alloy steel that actually holds its shape under high-frequency impact. Stocked and ready when site downtime gets expensive.

Highlights
Key Advantages
  • Machined to match Epiroc print for 3201195127—slips in without grinding or shimming
  • Heat-treated alloy holds ring diameter longer under continuous percussion in hard formations
  • No gap distortion after break-in; keeps the shank aligned so you don't waste rods
  • Used across RD18U and RD22U carriers in both underground headings and surface quarries
  • Batch-checked for hardness and inner chamfer—no sharp edges that score the piston
Use Cases
Applications
  • Epiroc RD18U face rigs pulling drifting rounds in hard-rock mines
  • RD22U long-feed rigs on quarry benches and construction cuts

FAQ
FAQ
Do I need to modify the front guide to fit this ring?
No. The 3201195127 ring drops straight into the RD18U and RD22U guide bores. We hold the same OD and thickness as the Epiroc drawing, so it seats without honing or shimming.
How long does the ring last in abrasive ground?
Life depends on rock hardness and flush pressure, but our alloy stands up better than many shelf-stock rings. Customers in granite and quartzite report getting through 30–40% more rods before swap-out compared to cheap aftermarket copies.
What’s the typical shipping time from your warehouse?
We keep this part on the shelf. Once your PO clears, it ships same day by air or express courier. Most mining hubs see delivery inside 4–6 business days. Urgent orders can go faster—just ask.
Is this just another universal ring stamped with a part number?
No. We batch-test Rockwell hardness and check the inner land width with go/no-go gauges. If it doesn’t match the Epiroc tolerance band, it doesn’t leave the shop. You won’t get a ring that jams the shank or lets it wobble.
Can you help if the old ring seized and galled the guide?
Call us with the rig serial and we’ll walk you through the cleanup steps. We can also supply the mating front guide sleeve if the bore is too scored to reuse—one less headache for your fitters.
