Black oxide steel sprocket with 16 teeth and 5/8 inch plain bore

Tsubaki

Tsubaki 41B16 Sprocket 41 Chain 5/8 Bore 16 Teeth

SKU CH-0Q7H-DM2EW

A 16-tooth steel sprocket for 41 chain with a 5/8-inch plain bore and keyway

  • Product typeSprockets
  • Precision fit for #41 chain with 16 hardened teeth
  • 5/8 in plain bore with 3/16 in keyway for secure shaft locking
  • 1045 steel construction with black oxide finish resists wear and corrosion
  • 81 in outside diameter matches standard drive dimensions
  • Includes set screws for immediate installation without extra hardware

TSUBAKI 41B16 Sprocket for #41 Chain

The TSUBAKI 41B16 sprocket is a steel power-transmission component machined for #41 roller chain with a 1/2 in pitch. It suits machinery builders and maintenance technicians who need a single-strand drive element with a plain 5/8 in bore and an integral keyway for positive torque transfer.

Black-oxide 1045 steel runs cool and quiet

Hardened 1045 carbon steel with a black-oxide finish resists wear and corrosion while the precision tooth profile keeps chain engagement smooth. The plain bore and set-screw locking method avoid the vibration and power loss that can come from loose fits, so the drivetrain stays efficient under normal loads.

2.81 in outside diameter fits compact layouts

A 2.81 in outside diameter and 2.563 in pitch diameter let the sprocket sit inside tight guards or between bearings without major redesign. The 7/8 in length through bore and 2 1/16 in hub diameter leave shaft length free for adjacent components, while the included set screws and 3/16 in keyway secure the mount without extra hardware.

Questions about this item

How do I install the 5/8 in plain bore sprocket onto a shaft without a keyway slot?

Slide the sprocket onto the 5/8 in shaft, align the included set screws with the flat on the shaft or drill a dimple, then tighten both set screws evenly to secure it against rotation and axial movement.

What maintenance does the 1045 steel sprocket with black oxide finish need during service?

Inspect the 16 teeth for hook wear and check chain elongation regularly; re-lubricate the roller chain at the 1/2 in pitch intervals and re-tighten the set screws if vibration loosens them.

At what point does the 2.563 in pitch diameter limit power transmission under continuous load?

The 1045 carbon steel teeth and 7/8 in length through bore reach their shear and wear limit when chain tension exceeds the material's yield, causing tooth deformation or keyway elongation at the 3/16 in keyway width.
