Backlash-free, torsionally rigid, all-steel, multi-plate disc couplings

Torque capacity up to 2,000,000 Nm. These 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.

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.
