CRV-S

CRV-S high precision reduction gears are based on a unique eccentric reduction mechanism and a special design of the radial and axial output bearing. As a result, they represent High rigid and high accurate power transmission systems. The CRV-S indicates the full integration of a high precision unique eccentric reduction gear with a radial and axial bearing in a single unit. This new transmission concept allows the use of the reduction gears directly in robot joints, rotary tables and wheel gears in various transport systems. The CRV-S is high precision Zero backless reduction gears are designed for applications requiring a high reduction ratio, high kinematic accuracy, low lost motion, high moment capacity and high stiffness of a compact design with limited installation space and low mass.

Advantages

  • High tilting stiffness
