Power Drive C4016X3/4 Fixed Bore Chain Coupling Sprocket 3/4 in Bore

SKU CH-W58J-PHKYS MPN C4016X3/4

Chain coupling sprocket for 1/2 in pitch chain with 16 teeth and 3/4 in keyed bore

  • TypeDrain Components
  • Steel construction delivers long service life
  • 16-tooth design handles 4.14 hp at 100 rpm
  • 3/4 in round keyed bore fits standard shafts
  • 005 in parallel misalignment tolerance eases alignment
  • 1 deg angular and .06 in axial freedom absorbs vibration

Fixed Bore Chain Coupling Sprocket

The Power Drive C4016X3/4 is a steel chain coupling sprocket designed for mechanical power transmission. It fits a 3/4 inch round keyed bore and works with number 40 chain at a 1/2 inch pitch. This component suits maintenance engineers and original equipment builders who need a reliable drive connection.

Thermals Noise and Power Draw

As a passive steel sprocket it generates no operational noise and draws no electrical power. Thermal output is limited to ambient heat from the driven machinery. The coupling tolerates a maximum angular misalignment of 1 degree and parallel misalignment of .005 in during normal rotation.

Replaces Worn Sprockets

This sprocket directly replaces a worn or damaged number 40 chain coupling sprocket with a 3/4 inch bore and 16 teeth. The upgrade is worth it when the existing hub shows keyway wear beyond 3/32 in depth or when axial motion exceeds .06 in. It pairs with cover part number AL40 for enclosed protection.

Questions about this item

How do I install the C4016X3/4 sprocket on a 3/4 in shaft, and what step is often missed?

Slide the fixed bore sprocket onto the shaft, align the 3/16 in wide by 3/32 in deep keyway with the shaft key, and secure the set screw; the step often missed is fully seating the key before tightening the set screw.

What maintenance or replacement will the chain coupling need over time?

Inspect the chain for wear and elongation, lubricate per the manufacturer schedule, and replace the chain or the 16-tooth sprocket when pitch stretch exceeds the 0.005 in parallel misalignment allowance.

What is the first limit reached under sustained high-speed operation?

The 16.9 hp rating at 4,000 RPM is the thermal and mechanical ceiling; exceeding it will cause premature wear on the teeth and hub before the 1 degree angular misalignment limit is reached.
