Backlash-free, torsionally rigid, ATEX certificated couplings.

A range of disc couplings utilize disc packs with 6, 8 or 10 bolt designs. Used wherever reliable torque transmission is called for, even in cases of often unavoidable shaft misalignment.

They are universally applicable over a temperature range of from -50°C (or even as low as -60°C on request) up to +280°C, are torsionally rigid, free of torsional backlash and enable quiet running at a constant angular velocity. They are wear-free and maintenance-free and, if correctly fitted, can be expected to have an unlimited service life.

An optimised plate pack and a reworked component part design enable even higher torques and speeds to be transmitted.

Attributes of the Disc Coupling Range:

  • Eliminates the need for lubrication and coupling maintenance.
  • Coupling can be inspected without disassembly.
  • Condition of disc packs can be inspected with a strobe light while the machine is running. (Note: It is not recommended that couplings be operated without coupling guards.)
  • Easy to assess equipment misalignment.
  • Torsionally rigid without any backlash.
  • No wearing parts.
  • Resistance to harsh environments.
  • Long life when properly sized and aligned.
  • High power density (higher torque for a given outside diameter).
  • Meet the requirement of API 610. Couplings in accordance with API 671 are also possible.
  • ATEX Certified on request.
