Neoprene sleeve coupling insert, two-piece with retaining ring, black finish

Tb Wood'S

Tb Wood'S 9N Sure-Flex Sleeve Coupling Insert Neoprene

SKU CH-G1G3-K425V

Neoprene sleeve coupling insert for size 9 couplings, rated 2,340 in-lb torque and 3,750 RPM with 3.7 hp at 100 RPM

  • Handles 3.7 hp at 100 RPM for reliable power transfer
  • Runs up to 750 RPM for high-speed machinery
  • Withstands 200 °F operating temperature in tough environments
  • Absorbs 0.025 in parallel misalignment to protect connected equipment
  • Delivers 6,875 in-lb/rad torsional stiffness for precise motion control

Coupling Insert for Size 9

This neoprene sleeve coupling insert fits Tb Wood's Sure-Flex size 9 couplings. It connects driving and driven shafts in industrial power-transmission systems. The two-piece design with a retaining ring simplifies installation and replacement on blowers, compressors, conveyors, mixers, motors and pumps.

3,750 RPM Maximum Speed

The insert is rated for a top speed of 3,750 RPM. Exceeding this limit risks premature wear or failure. At 100 RPM it transmits 3.7 horsepower. Angular misalignment capacity is 1 degree and parallel offset capacity is 0.025 inches.

2,340 in-lb Torque Capacity

Maximum torque rating is 2,340 in-lb with torsional stiffness of 6,875 in-lb per radian. This provides adequate headroom for typical pump and conveyor loads. The neoprene material withstands operating temperatures up to 200 degrees Fahrenheit. Buyers needing higher torque or speed ratings must select a larger coupling size.

Questions about this item

What does 3.7 hp at 100 RPM mean for my motor?

It is the continuous power the insert can transmit at that speed; above 100 RPM the allowable power changes proportionally with torque and speed limits.

How does the 3,750 RPM ceiling affect my drive line?

The neoprene sleeve is rated to 3,750 RPM; running faster risks heat buildup and premature wear.

What shaft spacing and alignment does the 6 in outside diameter require?

The 6 in OD sets the hub gap; you must keep angular offset within 1 degree and parallel offset within 0.025 in for rated life.
