DIR & DILR Type (Drop-In Spacer) Coupling

  • Direct Replacement for floating shafts in flanged series gear couplings
  • No need for lubrication or maintenance
  • Can utilize existing rigid Flanged Gear hubs or custom paper machine hubs
  • Can be inspected while in operation
  • Can run at higher speeds than floating shaft gear couplings
  • Unitized disc pack
  • Infinite life if properly aligned
  • Torsionally rigid with minimal back lash
  • No wearing parts and high resistance to harsh environmental conditions
  • Shim kits are standard for ease of installation and precise spacer positioning
  • Anti Flail / Anti Fly piloting option is standard to prevent the spacer assembly from flying out if a disc pack and bolts fail
  • Adjustable lengths using shaft locking devices
  • ATEX Certified

DIR & DILR Type (Drop-In Spacer) Coupling Additional Resources

  • DIR is provided with F-Style rigid gear coupling hubs
  • DILR manufactured to work with existing rigid hubs without disturbing the equipment
  • All spacers are manufactured to the customer’s specified length and a 2.0 service factor

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.
