Flexible mechanical coupling replaces BOTH Universal Joints and Jaw Type couplings

Twin Spring Coupling TSC300– Flexible Mechanical coupling to replace U joints & Jaw couplings

The Twin Spring Coupling offers the following advantages over a Universal joint or a L Jaw type coupling.

  • No internal components that need to be greased and replaced when worn
  • Flexible to 35°
  • One-piece design so no bearing kits to replace, no broken yokes or hubs.
  • Twin torsion springs makes it torsionally rigid at high speed
  • No wear parts like spiders or bearings to replace

Where would you use this?

  • Need a coupling that handles a large degree of misalignment but DON’T want the maintenance overhead of using Universal Joints
  • Use Jaw type coupling but the internal spider keeps wearing out due to the angle of misalignment.
  • Using couplings in a 24/7/365 situation (like conveyor belts) that any downtime due to bearing failures

Twin Spring Coupling offers 3 different torque rated couplings TSC150, TSC300 & TSC 500 available in all spline types and sizes.
