Tsubaki 40 Chain Sprocket 45 Teeth

The Tsubaki 40SDS45 is a steel power-transmission sprocket designed for single-strand 40 chain with a 1/2 inch pitch. It carries 45 teeth and a 7.45 in outside diameter to deliver smooth engagement in industrial machinery drives.

Suits drives needing SDS quick-detachable bushing

This sprocket fits an SDS bushing with a maximum bore of 2 in and a minimum bore of 1/2 in, making it appropriate for shafts within that range. Builders who require a different bushing style, a multi-strand chain, or a tooth count other than 45 should select another model.

Heat-treated 1045 steel with black oxide finish

The Grade 1045 steel construction resists wear under continuous load, while the black oxide coating adds corrosion resistance for extended service in harsh environments. A 3 3/16 in hub diameter and .466 in hub projection provide rigid mounting through a 3/4 in length through bore.

  • 45 in outside diameter fits standard drive layouts

Questions about this item

Which SDS quick-detachable bushing do I need to mount this 45-tooth sprocket on my shaft?

Any SDS bushing with a bore between 1/2 in and 2 in will fit the hub; choose the bore that matches your shaft size.

Will this single-strand 40-chain sprocket run correctly with an existing 40-chain drive that uses a smaller pinion?

Yes, the 1/2 in pitch and 7.168 in pitch diameter match standard 40-chain geometry, so it meshes with any compatible 40-chain sprocket.

How can I confirm the sprocket is seated properly after installing the SDS bushing?

The hub face should sit flush against the bushing flange with no visible gap, and the 3/4 in length through bore should fully engage the bushing.
