Sprocket Identity & Purpose

The Tritan 35BS25H is a finished-bore steel sprocket designed for 35 chain size with a 3/4 in bore and 25 teeth. It suits maintenance teams replacing worn drive components or builders assembling low-speed power-transmission rigs where a fixed hub and keyway are required. It is not for buyers who need a different bore diameter, tooth count or chain pitch.

Capacity & Headroom

With a pitch diameter of 2.992 in and outside diameter of 3.19 in, the sprocket handles standard 3/8 in pitch loads within the 35 chain rating. The 3/16 in keyway width and 3/32 in depth transmit torque positively, while two set screws lock the hub securely. It runs out when the application demands more than 25 teeth, a larger bore or multi-strand chain.

Interface Limits

The fixed-bore design accepts only a 3/4 in shaft with a matching keyway; no bushings or adapters are included. The 0.707 in hub projection and 2 in hub diameter set the axial space needed. The black-oxide finish resists light corrosion but is not a substitute for hardened teeth in abrasive or high-cycle environments.

Questions about this item

Will the 3/4 in bore with 3/16 in keyway fit the shaft I already have?

The sprocket has a fixed 3/4 in bore, a 3/16 in wide keyway cut 3/32 in deep, and two set screws to lock it onto a matching shaft.

How can I confirm the 25-tooth sprocket meshes correctly with my 35 chain after installation?

Turn the drive by hand and watch the 25 teeth engage the 3/8 in pitch chain smoothly; the 2.992 in pitch diameter and 3.19 in outside diameter should show no tight spots or tooth skipping.

Does the box include the two set screws, or do I need to buy them separately?

The package comes with the steel sprocket finished in black oxide and the two set screws already supplied; no extra fasteners are required.
