TRITAN 50BS24H Sprocket 24T 50 Chain 1in Bore

This finished-bore sprocket has 24 teeth and fits 50 chain with a 1 inch bore. It includes a 1/4 inch keyway, 1/8 inch deep, and two set screws for positive locking on a shaft. The steel body has a black oxide finish and a 3 inch hub diameter. It suits power transmission drives needing a fixed bore with keyway engagement.

Installation notes and common issues

Slide the sprocket onto a 1 inch shaft, align the key in the 1/4 inch keyway, then tighten both set screws against the flat or key. The hub projection is .907 inch and the length through bore is 1 1/4 inch, so confirm clearance before final torque. Misalignment or loose set screws are the usual causes of premature wear or noise.

Key specification for selection

The pitch diameter is 4.788 inch and the outside diameter is 5.12 inch, which together define the chain wrap and speed ratio for 50 chain. Verify these dimensions against your drive layout before ordering. Buyers who need a different tooth count, bore size, or chain pitch cannot use this part.
