Thomas Disc Couplings

Thomas Disc Couplings are torsionally rigid, all-metal flexible couplings that require no regular maintenance or lubrication. Angular, parallel, and axial misalignment are accommodated through flexible disc packs which can be visually inspected without disconnecting equipment.

Thomas couplings are engineered for infinite life and optimized for motor, engine, and turbine-driven applications. With over 100 years of coupling manufacturing history and Rexnord’s dedication to conservative design practices, the Thomas brand is trusted for its reliability on the most critical power train systems.

Optimized coupling design delivering low weight and high torque density for general purpose and critical ANSI/API process pump, fan, and compressor drive applications. The modularity of XTSR platform extends across various models to offer broad application coverage:

  • XTSR52: Non-adapter style spacer model enhances legacy Series 52
  • XTSR71: Adapter-style spacer model enhances legacy Series 71
  • XTSRLS: Long span / floating shaft
  • XTSRS: Single flexing
  • XTSRGA: Long span gear coupling replacement
