Black EPDM rubber sleeve coupling insert with retaining ring

Tb Wood'S

Tb Wood'S 8E Sure-Flex Sleeve Coupling Insert EPDM Rubber

SKU CH-BRPC-8VQE4

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

  • EPDM rubber withstands 275 °F continuous operation
  • 4,500 RPM rating suits high-speed drives
  • 1,475 in-lb torque capacity handles heavy loads
  • 1° angular and .02 in parallel misalignment tolerance
  • 3 hp at 100 RPM for blower, pump and compressor duty

Coupling insert for 4 500 RPM machinery

The Tb Wood'S 8E Sure-Flex sleeve coupling insert is built for inch-system power-transmission drives on blowers, compressors, conveyors, mixers, motors and pumps. Its EPDM rubber construction handles a maximum speed of 4 500 RPM and a peak torque of 1 475 in-lb. The two-piece design with a retaining ring simplifies installation on existing shafts.

EPDM rubber rated to 275 °F

At 100 RPM the insert transmits 2.3 hp while torsional stiffness of 4 335 in-lb/rad limits wind-up under load. Angular misalignment capacity is 1 degree and parallel offset is 0.02 in, reducing vibration transmitted to connected equipment. The material remains stable up to a maximum operating temperature of 275 degrees Fahrenheit.

Two-piece construction with retaining ring

The split insert and ring allow replacement without moving the coupled hubs, saving downtime on scheduled maintenance. An outside diameter of 5 1/16 in and an insert width of 2 1/2 in define the envelope needed inside the guard. California Proposition 65 warnings apply for cancer and reproductive-harm substances.

Questions about this item

How do I install the 8E Sure-Flex sleeve coupling insert and which step is commonly missed?

Slide the two-piece EPDM insert over the hub teeth, then secure the retaining ring fully into its groove; the step often missed is confirming the ring seats completely around the circumference.

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

Inspect the EPDM rubber for cracking, hardening or loss of elasticity caused by heat and torque cycles; replace the insert when torsional stiffness drops or visible degradation appears.

What limit appears first when the coupling runs continuously at high load?

The 275 °F maximum operating temperature is typically reached before the 4,500 RPM speed ceiling or the 1,475 in-lb torque rating under sustained heavy-duty use.
