• ADB Series - Aluminum Double Beam Clamp Style Couplings - Imperial
  • ADB Series - Aluminum Double Beam Clamp Style Couplings - Imperial-2
    The ADB (Aluminum Double Beam) Series coupling enhances the beam coupling options available from Lovejoy Inc. The longer overall length allows the ADB series to span longer BSE (between shaft end) measurements.

    The aluminum material used in its construction keeps the coupling’s weight low. The ADB design offers two flex points allowing for greater angular misalignment, up to 7°. This design also allows for up to .024 inches of parallel misalignment. The torque capacity ADB series is more than double the range of the single beam designs, with the largest size having a torque capacity of 88 in-lbs.
