Power Drive C4016X 1 1/4 Chain Coupling Sprocket 16T

SKU CH-46CY-EJBX0 MPN C4016X

A steel chain coupling sprocket with 16 teeth, 1 1/4 inch keyed bore, and 4.14 hp at 100 RPM

  • Product typeDrain Components
  • 16-tooth design matches ANSI 40 chain pitch
  • 1 1/4 inch round keyed bore fits standard shafts
  • 14 hp at 100 RPM for reliable power transfer
  • 1 degree angular and 0.005 inch parallel misalignment tolerance
  • 06 inch axial motion capacity handles shaft movement

Fixed-bore chain coupling sprocket

The Power Drive C4016X is a 16-tooth sprocket designed for #40 chain with a 1/2 inch pitch. It features a 1-1/4 inch round keyed bore with a 1/4 inch keyway width and 1/8 inch depth. This component suits maintenance teams and original-equipment builders who need a direct replacement for worn coupling halves in inch-measurement drive lines.

Sustained-load power capacity

At 100 RPM the sprocket transmits 4.14 hp, rising to 16.9 hp at the 4,000 RPM maximum rating. The steel hub of 1-3/8 inch diameter and 3 inch outside diameter with chain withstands continuous torque while allowing 0.06 inch axial motion and only 0.005 inch parallel misalignment. Angular misalignment is limited to 1 degree, so alignment discipline matters for long service life.

Upgrade from worn or undersized halves

The part replaces a damaged or stretched #40 sprocket half without changing chain pitch or bore size. The jump is worth it when inspection shows tooth hooking, keyway wear or coupling vibration that exceeds the stated misalignment limits. Buyers needing a different bore diameter, tooth count or chain size must select another model.

Questions about this item

How much heat or noise does the 16-tooth sprocket generate when running continuously at 4,000 RPM?

The sprocket itself has no motor or fan, so it produces no measurable heat or noise; any sound comes from the chain mesh and the driven equipment.

What shaft size and keyway must already be on the machine to mount this C4016X sprocket?

A 1-1/4 inch round shaft with a 1/4 inch wide by 1/8 inch deep keyway is required for the fixed-bore hub.

Will the 1-degree angular and 0.005-inch parallel misalignment limits work with older chain drives that have worn sprockets?

Worn sprockets increase misalignment; staying within the 1-degree angular and 0.005-inch parallel limits is essential to avoid premature wear on the new sprocket.
