Tb Wood'S 8JN Sure-Flex Sleeve Coupling Insert Neoprene

SKU CH-ZBXW-ZXE72

Neoprene sleeve coupling insert handles up to 4,500 RPM and 1,475 in-lb torque for blowers, compressors, conveyors, mixers, motors and pumps

  • Neoprene insert handles 1,475 in-lb torque for reliable power transmission
  • One-piece solid design rated to 4,500 RPM for high-speed applications
  • Angular misalignment capacity of 1 degree eases installation alignment
  • Parallel offset tolerance of 0.02 in reduces stress on connected shafts
  • Operating temperature up to 200 °F suits demanding industrial environments

Coupling Insert for Blowers and Compressors

This neoprene sleeve coupling insert fits size 8 Sure-Flex couplings used on blowers, compressors, conveyors, mixers, motors and pumps. It transmits up to 1,475 in-lb of torque at speeds up to 4,500 RPM. The one-piece solid construction handles angular misalignment of 1 degree and parallel offset of 0.02 in. It delivers 2.3 hp at 100 RPM with a torsional stiffness of 4,335 in-lb/rad.

Check Shaft Speed and Torque Limits

Verify that the driven equipment operates at or below 4,500 RPM and that peak torque does not exceed 1,475 in-lb. Confirm the coupling hubs on your shafts are also size 8 so the outside diameter of 5 1/16 in and insert width of 2 1/2 in match the existing assembly. Ensure the application temperature stays within the 200 degrees F maximum rating for neoprene.

Neoprene Insert Handles Misalignment Daily

The neoprene material absorbs vibration and accommodates up to 1 degree of angular misalignment plus 0.02 in of parallel offset during operation. Its solid one-piece design requires no lubrication and resists oil and ozone common in industrial environments. The inch-system dimensions simplify replacement on existing North American machinery.

Questions about this item

Does the 8JN coupling insert come with the two hubs or must they be purchased separately?

The 8JN is the neoprene sleeve insert only; the two coupling hubs are not included and must be sourced separately.

Which Sure-Flex size should I choose for a 2.3 hp motor running at 100 RPM?

The 8JN is rated for 2.3 hp at 100 RPM, so it matches that operating point directly.

What does the 4,500 RPM maximum speed mean for continuous operation on a pump?

4,500 RPM is the peak allowable speed; continuous pump duty should stay well below that limit and observe the 200 °F temperature ceiling.
