In the early 1990's Huco launched the Flex-M high integrity membrane coupling and this was followed by the Flex-B series of bellows couplings, another new and innovative design. With the recent addition of the Multi-Beam and Single-Beam

Rexnord® Thomas® Flexible Disc Couplings Overview A flexible coupling is a device used to connect the ends of two shafts, transmit torque, and at the same time, accommodate slight misalignments which develop in service . The primary functions of all flexible couplings are: 1 . To transmit power from one shaft to another, efficiently and

It is true that flexible couplings are designed to take misalignment, typically up to 400 mils or more radial offset of the shafts. But the load imposed on shafts, and thus the bearings and seals increase dramatically due to the reaction forces created within the coupling when misaligned. © 2002 PRUFTECHNIK LTD. 24 Causes of machine breakdown

Flexible Shaft Couplings. In many cases machine designers give limited thought to flexible shaft couplings. They devote their time to the more expensive components, overlooking the fact that the performance of a machine is only as good as the connections of its shafts. Reliance is fully aware of the importance of the shaft coupling and that
