Fenner Drives 6202400 Keyless Bushing 1 1/2in Shaft 2 3/8in OD

SKU CH-P4JK-ZE3NH

Keyless locking assembly for a 1 1/2 in shaft with a 2 3/8 in outside diameter transmits up to 583 ft-lb of torque using a single-nut steel design

  • Keyless locking eliminates keyway machining on 1 1/2 in shaft
  • Single-nut design simplifies installation and removal on 2 3/8 in OD
  • Oil-dipped steel finish resists corrosion in power-transmission environments
  • Rated for 583 ft-lb maximum transmitted torque at 6,500 psi hub pressure
  • OD tolerance held to ±.003 in for precise fit

Keyless Bushing for 1 1/2 in Shaft

This keyless bushing connects a 1 1/2 inch shaft to a 2 3/8 inch hub without keys or keyways. It suits maintenance teams and machine builders who need a backlash-free connection that can be installed and removed with standard hand tools. The single-nut locking assembly simplifies alignment during assembly.

Steel Construction with Oil-Dipped Finish

The body is made from steel and coated with an oil-dipped finish that resists corrosion in industrial environments. Its flange-free design and 2.75 inch overall width allow it to fit inside tight hub spaces where flanged units would interfere. The bore and outside diameters are held to a +/- 0.003 inch tolerance for consistent fit.

583 ft-lb Maximum Transmitted Torque

This rating determines whether the bushing can handle the application's peak load without slipping. The hub contact pressure reaches 6, 500 psi at full torque, so the hub material and wall thickness must be adequate to prevent distortion. Verify the torque requirement before specifying this part.

Questions about this item

What torque limit does the single-nut locking assembly enforce?

The assembly transmits up to 583 ft-lb before slip occurs, which is the practical ceiling for this bushing.

What shaft and bore dimensions must match for this keyless bushing to seat correctly?

It fits a 1 1/2 in shaft and seats in a 2 3/8 in bore with an outside-diameter tolerance of +/- 0.003 in.

How is the single-nut locking assembly installed, and what step is commonly missed?

Slide the bushing onto the shaft, insert into the hub bore, then tighten the single nut; the step often missed is confirming the 2.75 in overall width seats fully against the hub face before final torque.
