spider couplings

Spider Couplings are a class of coupling called Shock Absorbing Couplings - As a result of flexible plastic members connecting their hubs, these couplings dampen vibrations and shock loads and electrically insulate shafting.

  • Sizes: 1/8" to 1/2", 3mm to 12 mm
  • Torque Range: 42 in.-oz.-3520 in.-oz.
  • Range of Max. Para. Misalign.: .031" to .078"
  • Range of Max. Ang. Misalign.: 0°-1°

beam couplings

Beam Couplings are a class of coupling called Information Transmitting Couplings - These zero backlash, high torsional rigidity couplings are for precision positioning applications where constant velocity is required for accurate feedback control.

  • Types: Six Beam Flexible , Three Beam Flexible, Single Beam, Flexible, Reli-A-Flex
  • Torque Range: 5 in.-oz.-7,200 in.-oz.
  • Range of Max. Para. Misalign.: .004" to .038"
