3115173281 ATLAS COPCO 3115 1732 81 ROTATION CHUCK BUSHING

The 3115173281 Rotation Chuck Bushing is a key integrated gear & bushing assembly fitted inside the rotary gearbox of Atlas Copco COP1838 series hydraulic rock drifter. It combines spur driving gear and inner composite bearing sleeve into one piece, tasked with transmitting rotary torque from drive gear to shank driver, supporting radial load during high-speed rotating drilling.

Produced strictly per Atlas Copco OEM drawing standards, this chuck bushing realizes direct plug-and-play replacement of original factory spare parts. In harsh underground mine, tunnel and quarry sites filled with abrasive dust, continuous vibration and variable heavy load, it stabilizes rotary transmission, reduces eccentric wear of gearbox assembly and effectively cuts unexpected downtime of your Atlas Copco rock drill.
