Rigid couplings

Rigid couplings are ideal for lower speed or torque applications which require a direct and solid connection between two shafts of the same size.

What types of rigid coupling are available?

There are three types of rigid couplings: one-piece, two-piece and set screw. Each have different features and benefits, which make them ideal for different types of applications. 

One-piece rigid couplings

  • These couplings have a good holding power - superior to set screw rigid couplings.
  • Disassembly of surrounding equipment is needed for fitting.

Two-piece rigid couplings

  • These couplings have the highest holding power of all rigid couplings.
  • The two-part split design means that this coupling can be fitted and removed with little disassembly of surrounding equipment.

Set screw rigid couplings

  • This coupling is screwed into the shaft. This works best if the shaft is made of a softer material than the coupling. 
  • Disassembly of surrounding equipment is needed for fitting.
  • This coupling does not provide as high a holding power as one-piece or two-piece rigid couplings.

Rigid couplings FAQs

What is a rigid coupling?

A rigid coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. It provides a solid connection, ensuring precise alignment and torque transmission without any flexibility.

How do you install rigid coupling?

To install a rigid coupling, ensure both shafts are clean and aligned. Slide the coupling onto the shafts, aligning the keyways if applicable. Tighten the set screws or bolts securely to fix the coupling in place. Verify alignment and make any necessary adjustments before fully tightening.

What is the difference between rigid and flexible coupling?

The main difference between rigid and flexible couplings is their ability to accommodate misalignment. Rigid couplings provide a solid connection with no allowance for misalignment, while flexible couplings can accommodate some degree of misalignment and provide shock absorption.
