Epiroc Bushing 3128313618 for Boomer 281/K111 | OEM Pivot Wear Part | Drilling Rig Components

We specialize in supplying complete OEM wear parts for Epiroc drilling equipment. The genuine 3128313618 bushing features induction-hardened 4140 alloy steel with surface hardness HRC 60-62, engineered specifically for Boomer 281 and K111 drill boom pivot points. Its oil-impregnated bronze inner layer provides permanent lubrication, reducing friction by 45% in high-load applications like boom extension and rotation.

Precision-ground to ±0.01mm tolerance, this bushing prevents premature wear on pin joints subjected to 25-ton dynamic loads in hard rock formations. Our full range includes all critical Boomer series components – from hydraulic cylinders to guide rails – with same-day global shipping. For bulk orders, we provide customized wear analysis and preventive replacement schedules based on your drilling parameters and rock hardness.
