13-Tooth Steel Sprocket for #50 Chain

This new Tritan sprocket is a finished-bore power-transmission component built for #50 roller chain with a 5/8-inch pitch. It has 13 teeth, a 2.91-inch outside diameter and a 2.612-inch pitch diameter. The hub measures 1 7/8 inches in diameter with a 0.657-inch projection and a 1-inch length through bore.

Suited for fixed-shaft drives needing a 1 1/8-inch

The 1 1/8-inch bore includes a 1/4-inch wide by 1/8-inch deep keyway plus two set screws for positive locking on a keyed shaft. Builders needing a different bore size, a split hub, a larger tooth count or a multi-strand sprocket should select another part.

Handles single-strand #50 chain loads at this

The 13-tooth geometry and black-oxide steel construction suit typical drives at the 2.612-inch pitch diameter. Applications requiring higher speed ratios, greater torque capacity or a different chain size will exceed the practical range of this sprocket.

Questions about this item

What chain pitch and bore size must my existing shaft and chain match for the 13-tooth sprocket to fit?

The sprocket is made for 5/8 inch chain pitch and a fixed 1 1/8 inch bore with a 1/4 inch wide by 1/8 inch deep keyway.

Will the 1 7/8 inch hub diameter and .657 inch projection clear the adjacent bearing or frame on my current drive?

Hub diameter is 1 7/8 inches and projection is .657 inches; compare those dimensions to your existing clearance before installing.

How can I confirm the sprocket is seated correctly after tightening the two set screws?

Verify the key seats fully in the 1/4 inch keyway, the bore sits flush against the shaft shoulder, and the 2.91 inch outside diameter runs true with no wobble.
