Neoprene sleeve coupling insert for size 11 hubs handles 5,890 in-lb torque at 3,600 RPM with 1 degree angular and .032 in parallel misalignment capacity

  • Handles 9.4 hp at 100 RPM for reliable power transfer
  • Neoprene construction resists heat up to 200 °F in demanding applications
  • Two-piece design with retaining ring simplifies installation and maintenance
  • Accommodates 1° angular and .032 in parallel misalignment for smoother operation
  • Rated for 3,600 RPM and 5,890 in-lb torque in blower, pump and conveyor drives

Coupling Insert for Size 11

The Tb Wood'S 11N Sure-Flex sleeve coupling insert is a neoprene component designed for power transmission systems. It connects driving and driven equipment while damping vibration and accommodating misalignment. This new insert suits maintenance engineers and original equipment manufacturers specifying replacement parts for existing Size 11 couplings.

Fit for Blowers and Similar Loads

The insert suits applications such as blowers, compressors, conveyors, mixers, motors and pumps operating within the rated limits. It handles angular misalignment up to 1 degree and parallel offset of 0.032 in. Buyers needing higher torque capacity, different misalignment allowances or operation above 200 degrees F should look at alternative coupling sizes or designs.

Neoprene Insert Rated to 3,600 RPM

The single specification that decides fit is the maximum speed rating of 3,600 RPM combined with a torque limit of 5,890 in-lb. At 100 RPM the insert transmits 9.4 hp with a torsional stiffness of 17,300 in-lb/rad. Verify that the driven equipment speed and torque stay within these values before selecting this Size 11 neoprene insert.

Questions about this item

What comes in the box and do I need to buy the hubs separately?

The package contains the 11N neoprene sleeve insert with its retaining ring. The two coupling hubs that bolt to your shafts are sold separately.

How do I know the 11N is the right size for my application?

Choose the 11N when your system runs up to 3,600 RPM, needs up to 5,890 in-lb of torque and the shafts can tolerate 1 degree angular and 0.032 in parallel misalignment.

What does the 9.4 hp at 100 RPM rating tell me about everyday performance?

At 100 RPM the insert transmits 9.4 hp with a torsional stiffness of 17,300 in-lb/rad, and it remains within its 200 °F temperature limit for blower, compressor, conveyor, mixer, motor and pump drives.
