When it comes to crown gearheads, ebm-papst impresses with its innovative crown gearhead technology. It enables powerful, compact and highly efficient transmission solutions that can be produced extremely economically. The output shafts of all crown gearheads are made of ground, case-hardened steel and are thus especially robust. Torque is transmitted via a keyway connection as standard. A special feature of the crown gearheads is the lack of self-locking.
