Precision Power Transmission Component

The Tritan 40BS26H is a finished-bore roller chain sprocket designed for industrial power transmission systems. It suits maintenance engineers and machine builders who need a direct replacement for #40 chain drives with a fixed 3/4 inch bore. The steel construction with black oxide finish provides durability in standard operating environments.

26 Teeth Matches #40 Chain Pitch

This sprocket carries 26 teeth cut for a 1/2 inch chain pitch, yielding a 4.148 inch pitch diameter and 4.42 inch outside diameter. The tooth count and pitch diameter are the decisive figures; they must match the existing chain and centre distance exactly or the drive will not mesh correctly.

Keyway and Set Screws Enable Immediate Installation

A 3/16 inch keyway and two included set screws lock the sprocket to the shaft without additional machining. The one-inch length through bore and 3 1/4 inch hub diameter provide the registered fit, while the 0.716 inch hub projection clears adjacent components in typical assemblies.

Questions about this item

What does the 4.42 in outside diameter mean for chain clearance?

The 4.42 in outside diameter sets the minimum space the sprocket needs around its circumference so the chain links can engage without hitting guards or brackets.

How does the 1/2 in chain pitch limit the drive?

The 1/2 in pitch means this sprocket only works with ANSI 40 chain, fixing the tooth spacing and the maximum torque the chain can transmit.

Will the 3/4 in bore and 3/16 in keyway fit my shaft?

The sprocket has a fixed 3/4 in bore with a 3/16 in keyway and two set screws, so it mounts directly on a 3/4 in shaft with a matching key slot.
