Neoprene sleeve coupling insert, split one-piece design, 2 15/16 inch diameter

Tb Wood'S

Tb Wood'S 5JNS Sure-Flex Sleeve Coupling Insert Neoprene

SKU CH-KT8M-XQ2HA

Neoprene sleeve coupling insert rated for 7,600 RPM and 312 in-lb torque, operating up to 200°F in blower, compressor and pump drives

  • Neoprene sleeve handles 312 in-lb torque for reliable power transfer
  • One-piece split design simplifies installation and replacement on Coupling Size 5
  • Angular misalignment capacity of 1 degree protects connected equipment
  • Operates up to 7,600 RPM and 200 °F for demanding applications
  • Suited for blowers, compressors, conveyors, mixers, motors and pumps

Coupling Insert for Size 5

The TB WOODS 5JNS Sure-Flex sleeve coupling insert fits size 5 couplings and handles up to 7,600 RPM with a maximum torque of 312 in-lb. Its neoprene construction suits blowers, compressors, conveyors, mixers, motors and pumps. Buyers needing a different coupling size or a non-neoprene element should look elsewhere.

Sustained Load Behaviour

At 100 RPM the insert transmits 0.5 hp while its torsional stiffness of 916 in-lb/rad limits wind-up during continuous operation. It tolerates angular misalignment of 1 degree and parallel offset of 0.015 in without losing torque capacity. The maximum operating temperature of 200 degrees F sets the thermal ceiling for extended duty cycles.

Build and Mounting Implications

The one-piece split design with a 2 15/16 in outside diameter and 1 9/16 in width allows installation without fully disassembling connected shafts. Inch-system dimensions align with standard size 5 hubs for straightforward replacement. Users requiring metric bores or a solid unsplit insert will need a different component.
