Black rubber coupling insert with metal retaining ring, two-piece design

Tb Wood'S

Tb Wood'S 6E Sure-Flex Sleeve Coupling Insert, EPDM Rubber

SKU CH-BWA4-2B4GH

EPDM rubber sleeve coupling insert handles 585 in-lb torque at 6,000 RPM for blowers, compressors and pumps

  • EPDM rubber withstands 275 °F operating temperature
  • 585 in-lb maximum torque handles heavy loads
  • 6,000 RPM rating suits high-speed drives
  • 1° angular and 0.015 in parallel misalignment tolerance
  • 93 hp at 100 RPM for blower, compressor, pump applications

Product identity and intended use

The Tb Wood'S 6E Sure-Flex sleeve coupling insert is a flexible drive component designed to connect two shafts in industrial power-transmission systems. It suits maintenance teams and original-equipment builders who need a replaceable insert for existing 6E coupling hubs. The EPDM rubber construction targets applications such as blowers, compressors, conveyors, mixers, motors and pumps where vibration damping and misalignment tolerance are required. Condition is new.

Deciding specification

The insert is rated for a maximum speed of 6,000 RPM and a maximum torque of 585 in-lb, delivering 0.93 hp at 100 RPM. Its two-piece design with a retaining ring allows 1 degree of angular misalignment and 0.015 in of parallel misalignment, while torsional stiffness measures 1,718 in-lb/rad. These figures determine whether the insert matches the load and speed profile of the driven equipment.

Fit and alternatives

This part fits buyers who operate machinery within the stated speed, torque and temperature limits of 275 degrees F and who use inch-system coupling hubs sized for the 6E envelope. It is not for buyers who need higher torque capacity, greater misalignment allowances or a different insert material such as neoprene or polyurethane. The California Proposition 65 notice also means the product is restricted for users who must avoid the listed chemicals.

Questions about this item

What does the 0.93 hp at 100 RPM rating mean for a motor connected to this coupling?

It indicates the power the insert can transmit continuously at 100 RPM without exceeding its torque limit of 585 in-lb.

How does the 1 degree angular misalignment limit affect shaft alignment in practice?

The shafts must be aligned within 1 degree of angular offset; exceeding this accelerates EPDM wear and reduces the 6,000 RPM speed rating.

What shaft spacing does the 1 7/8 in insert width require?

The coupling halves must be spaced 1 7/8 in apart to fully seat the two-piece insert with its retaining ring.
