Piston

Created for maintenance and overhaul work on professional drilling equipment, the Piston (OEM BG00787332) is a high-strength aftermarket drifter piston for SANDVIK equipment including DD320 S, RDX5. It is a primary impact component that converts hydraulic energy into repeated striking force, transferring energy through the rock drill toward the shank adapter and drill string.

Produced from high-grade material with tightly controlled geometry and surface finish, the piston is designed for repeated high-frequency impact, hydraulic pressure and sliding contact. Accurate mass, alignment and working surfaces help support efficient energy transfer and stable drifter performance.

Offered as an alternative to the referenced OEM part, it gives maintenance teams a practical, cost-effective option without changing the intended installation concept.
