Tb Wood'S

Tb Wood'S 5E Sure-Flex Sleeve Coupling Insert, EPDM Rubber

SKU CH-B1H3-0JQEQ

EPDM rubber sleeve coupling insert rated for 7,600 RPM and 312 in-lb torque with 1 degree angular misalignment capacity

  • EPDM rubber withstands 275 °F operating temperature
  • Handles 312 in-lb maximum torque for demanding drives
  • Rated to 7,600 RPM for high-speed applications
  • Two-piece design with retaining ring simplifies installation
  • Absorbs 1° angular and 0.015 in parallel misalignment

Coupling Insert for Power Transmission

The Tb Wood'S 5E Sure-Flex sleeve coupling insert is designed for power transmission applications. It fits couplings in blowers, compressors, conveyors, mixers, motors and pumps. The EPDM rubber construction suits industrial machinery requiring flexible shaft connections.

Thermals and Power Characteristics

The insert operates at a maximum temperature of 275 degrees Fahrenheit during normal use. It handles a maximum torque of 312 in-lb and runs at speeds up to 7,600 RPM. Torsional stiffness is rated at 916 in-lb/rad with angular misalignment capacity of 1 degree and parallel misalignment of .015 in.

Size 5 Coupling Compatibility

This insert matches coupling size 5 with an outside diameter of 2 53/64 in and an insert width of 1 9/16 in. The two-piece design includes a retaining ring for assembly. Buyers needing a different coupling size or a non-EPDM material should select an alternative part.

Questions about this item

How do I install the two-piece insert with its retaining ring, and what step is often missed?

Separate the two halves, place each around the hub teeth, then snap the retaining ring into its groove to lock them together; skipping the ring lets the halves shift under torque.

What maintenance or replacement will this EPDM insert need over time?

Inspect the rubber for cracking, hardening or loss of elasticity caused by heat cycling up to 275 °F; replace the insert when torsional stiffness drops below the rated 916 in-lb/rad.

Which limit appears first during continuous operation at 7 600 RPM?

The 312 in-lb torque ceiling is reached before the 0.5 hp at 100 RPM rating, so sustained high-speed loading hits the torque limit first.
