What This Insert Does

The TB Wood's 5JS Sure-Flex sleeve coupling insert fits coupling size 5 and uses EPDM rubber to connect shafts in blowers, compressors, conveyors, mixers, motors and pumps. It transmits up to 312 in-lb of torque at speeds up to 7,600 RPM and operates at temperatures up to 275 degrees F.

Installing And Common Issues

The one-piece split design lets you place the insert between the two hubs without moving the connected equipment. Align the shafts within 1 degree angular and 0.015 in parallel limits; exceeding either will shorten the insert life and increase vibration.

Limits Of The Inch Standard

All critical dimensions — outside diameter 2 53/64 in, insert width 1 9/16 in, torsional stiffness 916 in-lb/rad — are stated in inch units. The insert delivers 0.5 hp at 100 RPM; applications that need higher power density or metric mounting patterns will require a different coupling system.

Questions about this item

How can I confirm the insert is running correctly after installation?

Verify the shaft speed stays at or below 7,600 RPM and the load does not exceed 312 in-lb of torque; the EPDM material is rated for up to 275 °F operating temperature.

What comes in the package and what must I source separately?

The box contains the 5JES EPDM sleeve coupling insert only; you must supply the two coupling hubs and any required fasteners.

Which insert version matches my 5-size coupling and application needs?

Choose the 5JES EPDM insert — it fits coupling size 5, handles 0.5 hp at 100 RPM, and tolerates 1 degree angular and 0.015 in parallel misalignment.
