Precision chain sprocket for 35-series drives

The Tritan 35BS20H is a finished-bore steel sprocket with 20 teeth cut for 35 chain pitch of 3/8 in. A 3/4 in fixed bore with a 3/16 in wide by 3/32 in deep keyway and two set screws locks it to the shaft, while the 1 15/16 in hub and 0.582 in projection keep the assembly compact.

Straightforward shaft mounting

Slide the sprocket onto a 3/4 in shaft, align the key in the keyway, then tighten both set screws against the key and shaft flat. The black-oxide finish resists light corrosion, but the bore tolerance is fixed — verify shaft diameter before ordering because no bushings or adapters are included.

Steady power transfer under load

Steel construction and a 2.397 in pitch diameter maintain accurate tooth engagement during continuous operation, reducing chain wear compared with softer materials. The 2.59 in outside diameter clears standard guards, and the single-strand design suits moderate-torque drives where a fixed-bore sprocket is preferred over a bushed alternative.

Questions about this item

How do I confirm the sprocket is seated correctly on a 3/4 in shaft after installation?

Verify the 3/4 in bore fits the shaft, the 3/16 in keyway aligns with the key, and both set screws engage the keyway and shaft flat.

What hardware is included and what must I supply separately?

Two set screws are included; you must provide the 3/16 in key, chain, and any shaft spacers or bearings.

Which chain size matches this 20-tooth sprocket?

It is made for 35 chain with a 3/8 in pitch; the 20 teeth give a 2.397 in pitch diameter and 2.59 in outside diameter.
