Piston

Built around the service demands of rock drilling machinery, the Piston (OEM 3115 1490 00) provides an aftermarket replacement path for the percussion and drifter assembly. It works within the impact and tool-drive path, where accurate alignment and repeatable energy transfer are important to drilling performance.

The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment. Listed compatible equipment includes COP 1238. Verify the exact machine variant before installation or ordering. Accurate fit and robust working surfaces help maintain energy transfer and alignment through the high-frequency load cycles produced during drilling.
