PV275 track idler
The Atlas Copco 57719288 Idler Assembly (Front Idler) is a genuine OEM-specification undercarriage component designed for the Atlas Copco PV271 and PV275 drilling rigs (now under Epiroc). This idler is a critical component that guides the track chain and maintains proper track tension at the front of the undercarriage.
The PV271 and PV275 are versatile drilling rigs used in underground mining for production drilling, bolting, and ground support applications. The idler features a precision-machined tread surface with induction hardening for maximum wear resistance. Advanced floating seals prevent contamination and retain lubrication, ensuring extended service life in severe underground conditions.
| Feature | Benefit |
|---|---|
| Induction-Hardened Tread Surface | Exceptional wear resistance in abrasive underground conditions |
| Floating / Duo-Cone Seals | Advanced sealing prevents contamination and retains lubrication |
| High-Strength Alloy Steel | Maximum durability for demanding drilling applications |
| Precision Bearings | Smooth rotation with minimal friction for extended service life |
| Heavy-Duty Construction (330 kg) | Robust build for underground mining conditions |
| PV271/PV275 Optimized | Specifically engineered for Atlas Copco/Epiroc drilling rigs |
| Direct OEM Replacement | Guaranteed fit and performance |
