Flex couplings – The best of a bad lot

The flexible coupling world has two offerings – high speed small angle of misalignment or lower speed , higher angle of misalignment but more maintenance.

Twin Spring now offers you the best of both worlds.

A high speed rigid coupling at low angles and a maintenance free high speed flexible coupling at higher speeds
How do we make the flex coupling work?

The Twin Springs patented design means the springs act like a beam coupling at low angles but more like a universal joint (angle wise anyway) at high angles, but since it contains no bearings unlike a universal joint our flexible coupling product is maintenance free.

So without bearings the coupling doesnt need to be regularly greased, saving time and money on maintenance.

High torque is another area where our flexible couplings excel where beam couplings can only take small amounts of torque, the design of beam couplings means they cant take torque without failing. With the thickness of the Twin springs we can handle torque loads only seen in universal joints.

So high speed, increased torque loads, increased angles of misalignment and no maintenance, what are you waiting for call us today to solve your flexible coupling nightmares.
