   *Information Displayed in Imperial Measurement
  1. All THRU BORE couplings have an inside relief so the shafts will not touch the beams at the maximum misalignment. All bores shown are thru bores.
  2. All LIMITED BORE couplings have the same OD have the same ID. The torque, stiffness and inertia are the same for all bores. When the bores are in blue, the maximum shaft penetration is E depth. When one bore is in white it can extend into the flexible area. Torque and wind-up is shown in blue.
  3. Any B1 may be combined with any B2. The smallest B2 bores cannot be duplicated in the B1 column where they are not already shown.
  4. Static torque is the maximum torque rating for each B1 bore. The correct dynamic torque safety factor should be determined by the customer in accordance with fast reversals acceleration, deceleration, sudden stops, etc.
  5. Torque and torsional stiffness ratings are at maximum misalignment, not in a straight line.
  6. Mass and inertia are calculated with the customers required B1 bore and the smallest B2 bore shown.
  7. Set screws are 120° apart. All screws are hex socket steel with black oxide finish. The torques are the screw manufacturers maximum ratings.
  8. Coupling material is 2024-T3.51 QQA225/6 aluminum with MIL A8625F Type II black anodize.
  9. Nickel plated couplings for added corrosion resistance are available for all Rocom couplings.
  10. G10 phenolic inserts for thermal and electrical isolation are available for all Rocom couplings.
  11. Clamps are an integral part of the coupling.
  12. Follow the installation procedures to ensure infinite life.
  13. TEST BEFORE YOU BUY. Rocom will furnish samples at no charge for all new OEM designs or for comparative evaluation.
