551 529 97 ROTATION BUSHING RD520 DRIFTER SANDVIK

The 551 529 97 ROTATION BUSHING RD520 DRIFTER SANDVIK is an essential component engineered to meet the extreme demands of modern rock drilling operations. This high-performance rotation bushing is specifically designed to operate within the Sandvik RD520 drifter system, ensuring smooth rotational movement, superior torque resistance, and extended service life under tough drilling conditions. Whether you’re tunneling, mining, or working in construction-grade environments, this part offers a reliable solution to minimize downtime and maximize performance.

Engineered for Demanding Environments

The 551 529 97 ROTATION BUSHING RD520 DRIFTER SANDVIK is manufactured using industrial-grade alloy steel and heat-treated to achieve superior hardness, wear resistance, and dimensional stability. Its tooth profile and internal splines are precisely machined to mesh flawlessly with companion components within the drifter’s rotation unit, reducing play and vibration during operation.

This component plays a vital role in the transfer of rotational motion from the hydraulic motor to the rock drill piston assembly, ensuring consistent power delivery during the drilling cycle. Its robust mechanical design allows for high rotational speeds while effectively handling shock loads and torsional stress.
