Precision gearboxes - Gearheads


Fast start-up with ready-to-install gears

Ready to install for fast integration

Nabtesco precision gearboxes are completely sealed gear units. They are filled with grease, encapsulated and ready for installation. To reduce the design and assembly costs, we integrate the motor adapter plate and the motor shaft coupling for servo motors in the precision gearboxes. The precision gearboxes are based on our different component sets – with a hollow shaft or solid shaft – and their design features bring numerous advantages.

Easy assembly

All gearheads form a completely sealed component. The basic features include an adapter plate for the motor and a motor shaft coupling for servo motors. This ensures fast and inexpensive installation of the gears. The large, integrated angular ball bearings in the gears absorb high forces and moments. This eliminates the need for additional bearings and minimises design and assembly times. The result: lower overall costs!
