New Series of Planetary Gearheads

high performance and longevity

ELRA’s new series of planetary gearheads ensures high performance and longevity. Unlike traditional precision gearheads, the new planetary gearheads series goes easy on the pocket. This makes it the perfect choice for wear-free motors, such as brushless DC motors or stepper motors.

All planetary wheels are mounted in needle bearings, ensuring a service life of up to 10.000h and more, depending on the application. ELRA’s new series of planetary gearheads achieve an efficiency level of more than 90% with very low backlash.

Key features:

  • All planetary wheels mounted in needle bearings
