Precision machined driver for Epiroc COP1638HD, COP1838, COP1838HD, COP1838HE and COP1838MUX series hydraulic rock drill drifters. Manufactured from premium heat-treated alloy steel, this torque transmission bushing ensures stable rotary power transfer, reliable shank connection and exceptional wear resistance in demanding mining and tunneling applications.
The 3115531400 Driver is a core torque transmission bushing component installed inside the rotary gearbox of Epiroc COP1638HD, COP1838, COP1838HD, COP1838HE and COP1838MUX hydraulic rock drill drifters. It connects the driving gear and drill shank, converting hydraulic motor torque into rotary cutting force for rock drilling. Precision machined from high-grade alloy steel with advanced heat treatment, the driver delivers stable torque output, prevents shank slipping and effectively reduces gearbox unexpected breakdown under continuous heavy-load operation in harsh mining conditions.
