  • Hub projection of .716 inch provides compact fit in tight assemblies

Precision Power Transmission Component

This finished-bore sprocket is engineered for single-strand 40 chain systems where exact pitch alignment matters. It suits maintenance teams and OEM builders who need a drop-in replacement with a 1 in bore and standard keyway. The steel body and black-oxide finish resist wear in continuous-duty drives.

Included Fasteners Simplify Installation

Two set screws and a machined keyway ship with the sprocket, removing the need to source separate locking hardware. The 1/4 in keyway width and 1/8 in depth match standard shaft profiles, so the hub locks securely without additional machining. This reduces downtime during scheduled overhauls or emergency repairs.

Single-Strand Chain Limits Apply

The 1/2 in pitch and 24-tooth geometry fix the speed ratio and torque capacity to the 40 series envelope. Multi-strand loads, higher pitch chains, or bore sizes beyond 1 in exceed the hub projection and diameter allowances. The 3.831 in pitch diameter and 4.1 in outside diameter also set the minimum guard clearance.

Questions about this item

Will the 1/4 in keyway or the two set screws need periodic adjustment on the 40 chain sprocket?

The 1/4 in wide keyway and two set screws hold the 1 in bore fast; inspect the key fit and screw torque during scheduled driveline maintenance.

Which dimension limits continuous operation first on the 24-tooth steel sprocket?

The 3.831 in pitch diameter sets the chain-wrap angle, so tooth engagement becomes the practical limit before hub stress.

How much heat does the black-oxide 4.1 in sprocket generate when run all day?

The steel body with black-oxide finish dissipates frictional heat through the 3 3/4 in hub; no forced cooling is required for normal speeds.
