The alpha Value Line impresses with economical and flexible solutions with backlash less than or equal to 8 arcmin. For example, the planetary and bevel gearboxes of the NP and NPK series are suitable for a wide range of applications thanks to numerous ratios and output versions – our “Individual Talents” give you new design freedom!

The alpha Value Line planetary and bevel gearboxes

Every detail counts

Unique modularity in this segment

With five series including five different output interfaces, the NP and NPK series offers maximum flexibility. From a simple machine connection using a B5 or B14 output flange to a flange connection or adjustment via slotted holes.

High economy

The gearboxes of the alpha Value Line are very economical to purchase, unbea¬tably efficient in operation, and mainte¬nance free over their entire service life. 

High flexibility

Modular configuration of the interfaces to the motor and to the application. The gearboxes are available with different clamping hub diameters, drive stages, design and mounting options. 

Highest power density

The HIGH TORQUE version provides gearboxes with the highest power density. 

Flexible motor connection

Mounting of all common servo motors by means of a flexible and screw-fastened adapter plate. Large number of motor shaft diameters connectable.

Fast sizing

Efficient online sizing within seconds in the SIZING ASSISTANT on the basis of the application data or the motor.
