Industrial Coupling Insert for Power Transmission

The Tb Wood'S 8HS Sure-Flex sleeve coupling insert is designed for mechanical power transmission systems. It connects shafts in equipment such as compressors, conveyors, electric motors, fans, blowers, mixers and pumps. The Hytrel insert handles a maximum torque of 530 in-lb and operates at speeds up to 4,500 RPM.

Thermals and Power Characteristics

The insert withstands a maximum operating temperature of 250 degrees F during normal operation. Its torsional stiffness is rated at 30,000 in-lb/rad, providing predictable torque transmission. Angular misalignment capacity is 0.25 degrees and parallel misalignment capacity is 0.015 in, reducing vibration and bearing loads.

Sustained Load Behaviour

At a continuous 100 RPM the insert transmits 7.2 hp within its rated limits. The two-piece construction allows replacement without moving connected equipment, supporting uptime in continuous-duty applications. It is not suited for drives requiring higher torque, speed or temperature ratings than those specified.

Questions about this item

How do I install the 8HS Hytrel insert into the coupling hubs without damaging the two-piece design?

Align the two-piece insert halves with the hub jaws, seat them evenly by hand pressure, then torque the hub bolts to the manufacturer's specification to avoid pinching the Hytrel material.

When should I replace the Hytrel insert based on wear or operating conditions?

Replace the insert if you observe cracking, chunking, or permanent deformation of the Hytrel material, or after exposure to temperatures exceeding 250 Degrees F during operation.

What is the first performance limit reached when running this coupling continuously at high load?

The torsional stiffness of 30,000 in-lb/rad combined with a maximum torque of 4,530 in-lb defines the limit before excessive wind-up or heat buildup occurs under sustained use.
