Tsubaki 40BTL36 Sprocket for Chain Size 40

The Tsubaki 40BTL36 is a single-strand sprocket designed for chain pitch 1/2 in and chain number 40. It features 36 teeth, a pitch diameter of 5.737 in and an outside diameter of 6.015 in. The steel body uses material grade 1045 with a black oxide finish for corrosion resistance. This component suits maintenance teams and OEM builders replacing worn drive sprockets on existing #40 roller chain systems.

Upgrade from worn or undersized #40 sprockets

A direct replacement is warranted when the current sprocket shows hooked teeth, excessive wear or incorrect tooth count for the drive ratio. The jump is worth it when the application demands the exact 36-tooth geometry to maintain proper chain engagement and speed reduction. The taper-lock hub accepts bushing size 1610 for secure shaft mounting without set-screw damage.

Verify shaft diameter and bushing compatibility

Confirm the driven shaft diameter falls within the 1 5/8 in minimum and maximum bore range before ordering. Ensure a 1610 taper-lock bushing is available or already installed, as the sprocket hub type is one-side with 0.716 in projection and 1 in length through bore. Check that the 3 in hub diameter clears adjacent components on the machinery.

Questions about this item

Does this sprocket need a specific bushing to mount on a shaft?

It is designed for a 1610 taper-lock bushing with a maximum bore of 1 5/8 in and a minimum bore of 1 5/8 in.

How do I install the taper-lock bushing correctly on this hub?

Clean the shaft and bushing bore, insert the bushing into the hub, tighten the set screws alternately to the recommended torque, and avoid over-tightening which can crack the hub.

When should I replace this sprocket due to wear?

Replace it when the 36 teeth show hooked or pointed profiles, the 1/2 in chain pitch no longer seats cleanly, or the black oxide finish has worn through exposing bare 1045 steel.
