Disc Coupling

Thomas XTSR52

The XTSR52 coupling is an all-purpose high-speed, high-torque coupling used where minimum coupling weight is desirable.

Thomas XTSR71

The XTSR71 couplings are designed for spacer type coupling critical applications including API applications.


Thomas SR54RDG

The Thomas® SR54RDG is a reduced diameter close coupled disc coupling. The split center member provides high speed and torque ratings while permitting service of the discs without disturbing connected equipment. Meets API 610 and 671 when specified.

Thomas SR52

The Thomas® SR52 coupling is a general purpose high speed high torque disc coupling.


Thomas SR71 & SR71-8

The Thomas® SR71 and SR71-8 are three piece design disc couplings where the hubs are a piloted fit to the factory assembled center member. The center member assembly provides fast installation and repeateable balance. Meets API 610 and 671 when specified.

Thomas SR72

The Rexnord Thomas® SR72 and SR72-8 are long span designs using components from the SR71 and SR71-8. The simple three piece design allows for easy installation and repeatable balance.


Thomas AMR/CMR

The Thomas® AMR/CMR couplings are used in heavy duty, slow to medium speed applications where shock loads, torque reversals or continuous alternating torque is present. CMR design uses a flywheel adapter plate to bolt directy to the flywheel of an engine or compressor.


The BSD Modulflex® torsionally stiff couplings are supplied in miniature designs as well as high performance versions up to 1 mNm and above. The modular design combined with high precision manufacturing and tolerances offers a variety of different solutions for the most challenging applications such as test benches or marine drives.
