Industrial Coupling Insert for Rotating Equipment
The TB Woods 9H Sure-Flex sleeve coupling insert connects shafts on compressors, conveyors, electric motors, fans, mixers and pumps. Its one-piece solid Hytrel construction handles a maximum torque of 7,200 in-lb and a maximum speed of 3,750 RPM. The insert delivers 11 hp at 100 RPM with torsional stiffness of 47,500 in-lb/rad. It suits new installations or replacement in inch-system power transmission drives.
Verify Shaft Alignment and Operating Limits
Confirm that angular misalignment does not exceed 0.25 degrees and parallel offset stays within 0.017 in before ordering. Ensure the application temperature remains below 250 degrees F and that the coupling outside diameter of 6 in fits the available space. The insert width of 3 in must match the existing sleeve dimensions for proper engagement.
Fits Standard Sure-Flex Flanges to Complete
This insert sits between two matching Sure-Flex flanges to form a flexible coupling that absorbs vibration and shock loads. It frees the connected equipment from rigid alignment constraints while transmitting rated torque. The Hytrel material resists oil and common industrial contaminants, reducing maintenance on the surrounding drivetrain components.

Questions about this item
What comes with the 9H Sure-Flex coupling insert and what else is needed to install it?
The package contains the Hytrel insert only; two matching 9H flanges and any required fasteners must be purchased separately.
How do I decide between the Hytrel insert and other materials for the 9H coupling?
Choose the Hytrel version when the application runs up to 250 °F and needs the 47,500 in-lb/rad torsional stiffness for compressors, conveyors, motors, fans, mixers or pumps.
What does the 11 hp at 100 RPM rating mean for actual machine operation?
At 100 RPM the coupling transmits 11 hp as long as torque stays below 7,200 in-lb, speed does not exceed 3,750 RPM, and misalignment remains within 0.25 degrees angular or 0.017 in parallel.
