Black EPDM rubber sleeve coupling insert with two-piece design and retaining ring, 6 inch outside diameter

Tb Wood'S

Tb Wood'S 9E Sure-Flex Sleeve Coupling Insert EPDM Rubber

SKU CH-8MB7-0S0T2

EPDM rubber sleeve coupling insert handles 3,750 RPM and 2,340 in-lb torque for blowers, compressors, conveyors, mixers, motors and pumps

  • EPDM rubber withstands 275 °F continuous operation
  • 7 hp transmitted at 100 RPM input speed
  • 3,750 RPM maximum speed handles high-cycle drives
  • 2,340 in-lb torque capacity absorbs shock loads
  • 025 in parallel misalignment tolerance eases shaft alignment

Coupling Insert for Size 9 Systems

This EPDM rubber sleeve coupling insert is built for Size 9 Sure-Flex couplings in power transmission assemblies. It connects driving and driven shafts while absorbing vibration and compensating for minor misalignment. The two-piece design with a retaining ring simplifies installation and replacement in industrial machinery. It suits maintenance teams and OEMs specifying flexible couplings for general-purpose equipment.

Fit for Standard Industrial Drives.

The insert handles angular misalignment up to 1 degree and parallel offset of 0.025 in, covering typical alignment drift in blowers, compressors, conveyors, mixers, motors and pumps. EPDM material resists heat up to 275 degrees F and common industrial environments. Buyers needing higher torque capacity, greater misalignment allowance or operation beyond the rated temperature should evaluate alternative coupling types or materials.

Rated for 2,340 in-lb Torque and 3,750 RPM

At 100 RPM the insert transmits 3.7 hp with a torsional stiffness of 6,875 in-lb/rad, providing predictable response for steady-load applications. The 6 in outside diameter and 3 in width define the envelope for guard design and shaft spacing. Continuous operation near the 3,750 RPM limit or at peak torque reduces service life; plan inspection intervals accordingly.

Questions about this item

What shaft size and coupling hubs must I already have to use this size 9 insert?

This insert fits size 9 Sure-Flex hubs with a 6 in outside diameter and 3 in insert width.

Can this EPDM rubber insert replace an older Hytrel or neoprene element on the same size 9 hubs?

Yes, it mounts on the same 2-piece hubs with retaining ring and handles 1 degree angular and 0.025 in parallel misalignment.

How do I confirm the insert is running within its 3,750 RPM and 275 °F limits after installation?

Monitor shaft speed to stay at or below 3,750 RPM and check housing temperature remains under 275 °F during operation.
