6HS Hytrel Coupling Insert for Power Transmission

This 6HS Sure-Flex sleeve coupling insert is made from Hytrel and fits Size 6 couplings. It transmits torque between shafts in compressors, conveyors, electric motors, fans, mixers and pumps. The insert handles a maximum torque of 1,800 in-lb and a maximum speed of 6,000 RPM. It is suited for maintenance engineers and plant mechanics replacing worn elastomeric elements in existing Sure-Flex hubs.

Two-piece design simplifies hub alignment during

The new two-piece construction allows the insert to be fitted without moving connected equipment or fully disassembling the hubs. Angular misalignment capacity is 0.25 degrees and parallel misalignment capacity is 0.01 in. The most common issue is exceeding these limits, which accelerates wear and can damage the hub teeth. Correct shaft alignment at assembly prevents premature failure.

Hytrel material sustains 2.9 hp at 100 RPM

Torsional stiffness is rated at 10,000 in-lb/rad, providing predictable torque transmission under continuous load. The insert operates reliably at temperatures up to 250 degrees F, making it suitable for extended duty cycles in industrial environments. It is not designed for applications requiring higher torque capacity or greater misalignment tolerance than the stated ratings.

Questions about this item

How can I verify the 6HS Hytrel insert is performing correctly after installation?

Confirm the driven equipment runs below 6,000 RPM and stays under 250 °F; listen for vibration that would indicate angular misalignment beyond 0.25 degrees or parallel offset above 0.01 in.

What components are included with the 6HS Sure-Flex sleeve coupling insert and what must be sourced separately?

The package contains the two-piece Hytrel insert only; matching flanges, fasteners and any required hubs are sold separately.

Which insert material should I select for a compressor or pump application requiring 1,800 in-lb torque capacity?

The Hytrel version listed here delivers the 1,800 in-lb rating and suits compressors, conveyors, motors, fans, mixers and pumps.
