Tsubaki 35B10 Sprocket for 35 Chain

This sprocket fits 35 pitch chain and provides 10 teeth for compact drives. The plain bore measures 3/8 in and can be reamed to a maximum of 9/16 in. Steel grade 1045 construction with black oxide finish resists wear in power transmission applications.

Upgrade from worn or undersized sprockets

Replacement is justified when tooth profiles show hooking or when chain stretch exceeds service limits. The included set screws and 3/64 in keyway depth secure the hub against rotation on the shaft. A 3/4 in length through bore distributes load across the keyway width of 3/32 in.

Handles single-strand 35 chain loads

The 1.214 in pitch diameter and 1.38 in outside diameter suit light to moderate torque requirements. Hub diameter of 1 in and projection of 0.582 in limit use to shafts within the bore range. Not suited for multi-strand chains or applications demanding larger pitch diameters.

Questions about this item

What shaft diameter and keyway dimensions does the 3/8 in bore with 3/64 in depth and 3/32 in width accept?

The plain bore is 3/8 in with a maximum of 9/16 in. The keyway is 3/64 in deep and 3/32 in wide, matching standard 3/8 in shaft keying.

How do I secure the sprocket on the shaft using the included set screws, and what is the common mistake?

Align the key in the 3/64 in deep keyway, then tighten both set screws against the key and shaft flats. The common mistake is tightening only one screw or skipping the key.

When should I replace this 1045 steel sprocket with 10 teeth running 35 chain?

Replace when tooth profiles show visible hooking, chain rollers no longer seat cleanly, or the 1.38 in outside diameter wears enough to increase chain slack beyond adjustment range.
