These couplings are for use in machinery where a torsionally rigid torque is required, especially on frequently varying loads and speeds.

KBT

These couplings are for use in machinery where a torsionally rigid torque is required, especially on frequently varying loads and speeds.

KFB

The KFB is a spring applied safety brake which is mainly used in gantry, trolley and hoisting application on harbour crane systems, in dynamic and static use at general industrial applications, in mechanical engineering, steel mills, coal mining or wind energy systems.

KH

These couplings are for use in application with high dynamic loads. Damping of peak torques and vibrations as well as electrical insulation between motor and gearbox are further reasons for the use of this coupling type.

N

The Hub with Brake Disc Type N + NX is appropriate for all drives, where the brake is not located between motor and gearbox, like brake installation on the second gear box shaft or at the motor end shaft.

Rope drum couplings are recommended for use in hoist mechanisms, winches or conveying applications to connect the gear box output shaft with the rope drum/ winch.

NX

The Hub with Brake Disc Type N + NX is appropriate for all drives, where the brake is not located between motor and gearbox, like brake installation on the second gear box shaft or at the motor end shaft.
