SX Type Industrial Disc Coupling Additional Resources

The SX Type coupling consists of:

  • Two – Hubs
  • One – Spacer
  • 2 – Disc Pack Kits (4, 6 or 8 bolt)

The coupling has two flex planes (one at each disc pack) so it can accommodate parallel misalignment by the angular misalignment in each disc pack. This configuration will also accommodate axial misalignment within the specified limits.
