Chain Coupling Sprocket 16T 7/8 in Bore

This Power Drive C4016X7/8 chain coupling sprocket connects two shafts using a number 40 roller chain. It suits maintenance engineers and plant mechanics who need to transmit rotary motion between aligned or slightly misaligned drives in industrial equipment.

1/2 in Chain Pitch and 16 Teeth

The sprocket is cut for 1/2 in pitch chain with 16 teeth, a 7/8 in round keyed bore, a 3/16 in keyway width and a 3/32 in keyway depth. These dimensions decide whether the sprocket matches the existing chain and shaft on the machine.

Direct Shaft Mount with Key

The round keyed bore slides onto the shaft and locks with a standard key; no special tools are required beyond a set screw or retaining ring. Misalignment beyond 1 degree angular or 0.005 in parallel will accelerate wear, so verify alignment before tightening.

Questions about this item

What does 4.14 hp at 100 RPM mean when this sprocket is installed?

At 100 RPM the sprocket can transmit 4.14 hp through a #40 chain, so a motor or engine running at that speed must not exceed that power level.

How does the 1/2 in chain pitch limit what this sprocket can do?

The 1/2 in pitch fixes the sprocket to #40 roller chain; it cannot run on larger or smaller pitch chains, and the chain itself becomes the practical strength limit.

What shaft and keyway dimensions are needed to mount this 7/8 in bore sprocket?

It fits a 7/8 in round shaft with a 3/16 in wide by 3/32 in deep keyway.
