The Epiroc 57467516 Top Roller Assembly (Carrier Roller) is a genuine OEM-specification undercarriage component designed for the Epiroc DMM3 drilling rig (formerly Atlas Copco DMM3, ITM Series). This top roller (carrier roller) supports the upper strand of the track chain, reducing track sag and ensuring proper alignment between the drive sprocket and idler.
The DMM3 is a versatile drilling rig used in underground mining for production drilling, bolting, and ground support applications. This carrier roller is manufactured from high-strength alloy steel with induction-hardened tread surfaces for maximum wear resistance in abrasive underground conditions.
| Feature | Benefit |
|---|---|
| Top Roller / Carrier Design | Supports upper track chain, reducing sag and vibration |
| Induction-Hardened Tread Surface | Exceptional wear resistance in abrasive mining conditions |
| Floating / Duo-Cone Seals | Prevents contamination and retains lubrication for extended life |
| Precision Bearings | Smooth rotation with minimal friction for extended service life |
| Heavy-Duty Construction (52 kg) | Robust build for demanding underground applications |
| DMM3 Optimized | Specifically engineered for Epiroc/Atlas Copco DMM3 drilling rig |
| Factory Lubricated | Maintenance-free sealed design |
