The Sandvik HL1560 Bushing 55052181 is used to support and guide moving components inside the rock drill while helping control clearance between adjoining parts. Its presence reduces direct contact between load-bearing surfaces and contributes to smoother movement during continuous percussion and rotation cycles.
Made for heavy-duty service in demanding drilling conditions, the 550 521 81 bushing is designed to withstand friction, vibration, and repeated mechanical loading. Supplied as a high-quality alternative spare part, it helps limit wear on surrounding components and supports stable operation in mining, quarrying, tunneling, and construction applications.
