CNC Rigid and Flexible Couplings


Custom Rigid & Flexible Couplings


Shaft couplings absorb misalignment and provide power and torque transmission between rotating shafts. Coleys couplings can be custom made to fit your application or selected from a wide array of standard hose coupling styles – each offering:

  • Varying speed, torque, and misalignment capabilities.
  • Higher PSI ratings and durability, up to 800 PSI.
  • Customizable to your unique application.
  • An array of styles such as billet or tubing, carbon, and stainless-steel.
  • Precision made with excellent cosmetic finishes.

Rigid Coupling vs. Flexible Coupling Applications

Both rigid and flexible couplings have their place in almost any complex motion system. Flexible couplings are generally preferred for applications where misalignment between the shafts can occur, while rigid couplings are ideal when you need high torque and torsional stiffness.

Rigid Coupling Applications

  • High-speed rotating machinery
  • Precision CNC machining
  • Robotics and automation
  • Power transmission systems

Flexible Coupling Applications

  • Electric motor driven equipment
  • Automotive industry applications
  • HVAC systems
  • Marine and offshore applications
