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.
