Finished bore sprocket for 40 chain

The Tritan 40BS35H is a steel sprocket with a fixed one-inch bore, keyway and two set screws included. It suits maintenance teams and machinery builders who need a direct replacement for single-strand 40 chain drives. The black oxide finish adds corrosion resistance for industrial environments. Collectors of power-transmission hardware may also value the precise factory specification.

Keyway and set screws simplify installation

A 1/4-inch wide by 1/8-inch deep keyway mates with a standard key to prevent rotation on the shaft. Two set screws provide additional axial locking without extra machining. The hub projects .716 inches with a 3 3/4-inch diameter, keeping the assembly compact. These features reduce downtime during sprocket swaps.

Thirty-five teeth on 40 chain pitch

The sprocket carries 35 teeth cut for 1/2-inch pitch chain, yielding a 5.578-inch pitch diameter and 5.86-inch outside diameter. This tooth count fixes the speed ratio, so the part only fits drives designed for that exact geometry. Buyers needing a different ratio or chain size must select another sprocket.

Questions about this item

How often should the set screws on the 1 in bore be checked and retorqued?

Inspect the two set screws after the first few hours of operation and then at regular maintenance intervals to maintain secure attachment to the shaft.

What wear limit on the 35-tooth steel sprocket appears first under continuous load?

Chain stretch will cause the 1/2 in pitch rollers to ride up on the 5.578 in pitch diameter teeth, so replace the sprocket once tooth profiles show visible hooking.

How much heat does the black-oxide finish generate during all-day operation?

The steel body with black oxide coating runs at ambient temperature; no measurable heat rise occurs from the finish itself during normal power-transmission duty.
