Neoprene sleeve coupling insert, solid one-piece construction, 2 15/16 inch outside diameter

Tb Wood'S

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

SKU CH-0TZJ-MWQ90

Neoprene sleeve coupling insert rated for 7,600 RPM and 312 in-lb torque, suitable for blowers, compressors and pumps

  • Neoprene insert handles 200 °F operating temperature
  • 312 in-lb torque capacity drives blowers and compressors
  • 1° angular misalignment tolerance protects connected equipment
  • 7,600 RPM maximum speed suits high-speed motors
  • 916 in-lb/rad torsional stiffness ensures precise power transfer

Application Fit

The neoprene sleeve coupling insert suits size 5 Sure-Flex couplings in blower, compressor, conveyor, mixer, motor and pump drives. It transmits up to 312 in-lb of torque at speeds not exceeding 7,600 RPM. One-piece solid construction simplifies replacement in inch-system power-transmission assemblies.

Thermal & Power Profile

Continuous operation is rated to 200 degrees F, and the neoprene material maintains damping within that range. At 100 RPM the insert handles 0.5 hp with torsional stiffness of 916 in-lb/rad. Angular misalignment of 1 degree and parallel offset of 0.015 in are absorbed without generating excess heat or vibration.

Sustained Load Behaviour

Under steady load the insert delivers consistent torque transmission up to the 312 in-lb limit while compensating for the rated misalignments. The solid one-piece design avoids fatigue points that can appear in split inserts during prolonged duty cycles. Performance remains stable provided speed and temperature stay within the stated 7,600 RPM and 200 degrees F boundaries.

Questions about this item

How do I install the 5JN sleeve coupling insert and what alignment step is often missed?

Slide the one-piece neoprene insert between the two coupling hubs so the 2 15/16 in outside diameter seats fully. The step often missed is verifying parallel offset stays within 0.015 in and angular misalignment within 1 degree before tightening the hubs.

What maintenance or replacement will the neoprene insert need over time?

Inspect the neoprene insert periodically for cracking, hardening or loss of elasticity caused by heat up to 200 °F. Replace the insert when torsional stiffness drops below the rated 916 in-lb/rad or when visual wear appears.

What is the first limit reached under continuous operation at 7,600 RPM?

The 7,600 RPM maximum speed rating is the first hard limit; exceeding it risks insert ejection. Torque is capped at 312 in-lb and horsepower at 0.5 hp at 100 RPM, but the speed ceiling arrives first in sustained high-speed runs.
