Planetary gears
High-tech products from the gear specialists Schray

Planetary gears from Schray drive technology are among the most compact drive elements available to the designer. They permit high torque transmission in the smallest space and are distinguished by their low distortion backlash.

Production range :
1-3 stage, from 4 to 150 Nm

Connections:
Suitable for connection to all motors:
Servomotors and electro-motors (AC/DC, 3-phase)

Design:
Open and closed design with customer specific input and output shafts (splined, special drive shafts)

Other advantages:

  • In addition to the standard speed reductions, Schray offers individual production to customer specific requirements

  • All components are manufactured at Schray - nothing is bought in from third parties

  • First-hand expert advice

Also in our product range:

  • Combined spur gear and planetary gears

  • Low backlash planetary gears
    due to the special surface and finish treatment of the deployed gears

The successful development and production of the gears is the result of a decade of Schray's experience in their manufacture of technically and qualitatively high grade gears and their surface treatment. The highest levels of quality are guaranteed to the customer through our DIN EN ISO 9002 certification.
