Rotation Chuck Bushing

Designed for consistent performance in heavy-duty drilling applications, the Rotation Chuck Bushing (OEM 3115 3440 00) is a compatible aftermarket component for Epiroc drill rigs and related rock-drilling equipment. The rotation-chuck bushing supports the rear shank/chuck interface, helping keep rotating components centered while torque and percussion loads are transferred through the drifter. Listed applications include COP 2160, COP 2560 and COP 2560EX, with additional compatible models shown in the product data.

Materials and contact surfaces are selected to handle the wear, load, vibration and repeated cycling associated with mobile drilling equipment. A sound bearing surface limits radial play, promotes smoother rotation and helps prevent uneven contact that can shorten the life of the chuck, shank and surrounding housing. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
