Bellows Coupling replacement technology - same high speed, higher torque and more flexible.

What Twin Spring Coupling can do for you

  • Speeds: Up to 7000 rpm
  • Peak Torque Largest Size ft lbs 150ft lbs (203Nm) to 500ft lbs (678 Nm)
  • Standard Coupling sizes .6 – 1 3/4” (15-45mm)
  • Temperature: -20° to +290°F , (-4° to +140°C)
  • Connection: Spline (Square, Hex, Keyway, No Keyway
  • Minimal backlash
  • Springs absorb vibration
  • No moving parts
  • One piece design 

Bellows couplings, similar to single beam or multi beam couplings, very rigid but with the downside of not being very flexible. You need a strong coupling but with some flex.

The power transmission coupling world has two offerings – high speed small angle of misalignment or lower speed , higher angle of misalignment but more maintenance.

Twin Spring now offers you the best of both worlds.

A high speed rigid coupling at low angles and a maintenance free high speed flexible coupling at higher speeds
How do we make the flex coupling work?

The Twin Springs patented design means the springs act like a beam coupling at low angles but more like a universal joint (angle wise anyway) at high angles, but since it contains no bearings unlike a universal joint our flexible coupling product is maintenance free.

So without bearings the coupling doesn’t need to be regularly greased, saving time and money on maintenance.

High torque is another area where our flexible couplings excel where other couplings can only take small amounts of torque, the design of the couplings means they cant take torque without failing. With the thickness of the Twin springs we can handle torque loads only seen in universal joints.

Why keep greasing and replacing worn universal joints bearings or worn out spiders in L type jaw couplings.

So high speed, increased torque loads, increased angles of misalignment and no maintenance, what are you waiting for call us today to solve your coupling nightmares.
