Stationary upgrades and engineered solutions

Conical main shaft sleeve

Next-generation parts mean smarter and safer routines.

With a conical design of both the main shaft and the pro­tective sleeve – combined with oil grooves embedded in the main shaft – it offers improved worker safety, shorter turnaround time, the elimination of grinder damage, and no heating process.

The service procedure of the main shaft sleeve requires a torque wrench and a hand-driven oil pump to release the main shaft sleeve. With our oil pressure-driven “pop-off” release solution, we’ve reduced the risks to workers, eliminated the grinding and heating procedures, and shortened the turnaround time. It’s safer, simpler and quicker.

Customer values
