Alignment Requirements: Flexible couplings can handle slightly misaligned shafts. Rigid couplings are torsionally stiff and can't tolerate 

Several factors should always be taken into consideration when looking to specify flexible shaft couplings. These are torsional stiffness, backlash, torque, life and attachment system. All of these have bearing on coupling selection.

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

Flexible couplingIt is a mechanical part used to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque.In high-speed and heavy-load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.

QUICK FLEX Coupling Torque Ratings with High-Speed Cover (Metric) Note: QUICK FLEX flexible couplings can sustain momentary peak torque loads up to 200 percent of their continuous torque rating .

If we look at the table under 1800 RPM, which is the most common RPM in industry, it shows the allowable tolerances divided into three ranges: Minimal - 6.0 mils of offset and 1.2 mils per inch of angle. Standard - 3.0 mils of offset and 0.6 mils per inch of angle. Precision - 1.6 mils of offset and 0.3 mils per inch of angle.

Alignment should be checked as part of the PM. The shaft onto which the coupling mounts should be of the proper size (and not sanded down 1-2

back as 1962. Other 'moving parts' couplings followed, notably the Uni-Lat and Oldham concepts. 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
