GEARex® couplings made from steel with grease lubrication and toroidal sealing ring correspond to the international standard. Being flexible shaft connections they are suitable for a positive torque transmission. In addition, they ensure to compensate for axial, radial and angular shaft displacements.

GEARex® couplings are used in every range of general engineering requesting for high operating safety and a long service life resulting from the reliable grease lubrication of the crowned spline. The couplings are suitable for horizontal assembly. As special solutions they are suitable for vertical assembly, too.

Numerous coupling sizes for a torque transmission from 930 Nm to 820.000 Nm with shaft dimensions up to a maximum of Ø 450 mm are available. The coupling torques may be increased by using special materials.

GEARex® couplings are in correspondence with the AGMA standard (American Gear Manufacturer Association). Small dimensions and a low weight along with a small mass moment of inertia result in a wide range of applications of GEARex® couplings.
