Crown gearheads

Outstanding efficiency


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.

All your advantages at a glance:  

  • No offset
  • Outstanding efficiency
  • Broad range of reduction ratios
  • No self-locking
  • Very high power density

Current series and their strengths



The EtaCrown® is a convincing offering with its wide reduction range and compact design. Space can always be saved during installation thanks to zero axle misalignment with a symmetrical structure. High radial loads can also be incorporated via a double ball bearing on the output shaft. 



The EtaCrown®Plus requires minimum assembly space while achieving maximum power. Thanks to a downstream planetary stage, it can achieve significantly higher torques compared to the EtaCrown® of the same size.
