Gear couplings

Gear couplings connect shafts using two hubs with external teeth and a sleeve with internal teeth that encloses both hubs. The hub teeth can tilt slightly inside the sleeve, which is why the coupling compensates for angular, axial and radial shaft misalignment.

Gear couplings - high torque with a small diameter

A gear coupling transmits high torque with a small diameter, so it fits where space is limited. You assemble it from parts: choose a short hub when the gap between machines is small, and a long one when better guidance on the shaft or a larger gap between shaft ends is needed. When worn, you replace only the component that needs it.

Short and long hubs and sleeves for gear couplings

Short hubs, long hubs and sleeves in several sizes. One coupling can use two short hubs, two long ones or one of each type. The size is given in the product name.

What does a gear coupling consist of - frequently asked questions

What does a complete gear coupling consist of?

Two hubs and one sleeve of the same size, e.g. two size 28 hubs and a size 28 sleeve.

Does a gear coupling require lubrication?

This depends on the sleeve version. Lubrication recommendations are given on the product page and in the manufacturer's instructions.
