TRITAN 50BS18H Sprocket

The TRITAN 50BS18H is a new finished-bore sprocket made from steel with a black oxide finish. It carries 18 teeth and is built for single-strand 50-series roller chain. The hub extends 0.657 in and measures 2 7/8 in in diameter with a 1 in length through bore. Two set screws and a 1/4 in wide by 1/8 in deep keyway secure the 1 in bore to the shaft.

Ideal for Power Transmission Repairs

Maintenance technicians and machinery builders who need a direct replacement for a worn 50-chain sprocket with a 1 in shaft will find the correct pitch diameter of 3.599 in and outside diameter of 3.92 in. Collectors of industrial hardware may also value the component. Buyers who require a different bore size, a different tooth count, or a multi-strand hub should select another part.

18-Tooth 50-Chain Specification

The defining specification is the 18-tooth profile matched to ANSI 50 chain pitch; this determines whether the sprocket will mesh with the existing chain and drive ratio. The fixed 1 in bore with keyway and dual set screws then confirms if it fits the target shaft without modification.

Questions about this item

Which chain size and tooth count should I select for my drive?

The sprocket is made for 50 chain size and has 18 teeth, so choose it when your system calls for that exact pitch and tooth count.

What does the 3.92 inch outside diameter mean once the sprocket is mounted?

The 3.92 inch outside diameter is the overall width across the tooth tips, determining clearance inside guards and the chain wrap radius on the shaft.

How does the 1 inch finished bore with keyway and set screws limit installation?

The 1 inch bore with 1/4 inch wide by 1/8 inch deep keyway and two set screws fixes the sprocket to a 1 inch shaft, preventing use on any other shaft diameter.
