Products
Reduced backlash helical gear units, parallel shaft helical gear units, and helical-bevel gear units
Reduced backlash vertical gear units / gearmotors
Helical gear units, parallel shaft helical gear units, and helical-bevel gear units with reduced backlash can be supplied in all configuration types and for all mounting positions of standard SEW gear units from size 7 upward.

SEW gearmotors with reduced backlash gear units are available as planetary, helical, parallel shaft, and helical-bevel gearmotors in many application-oriented mounting positions.

They stand out because of their high level of efficiency and high-endurance gearing. They are designed as both asynchronous and permanent-field synchronous motors, and are operated with MOVIDRIVE® drive inverters or MOVIDYN® servo controllers.
