Sprocket 60 Chain 28 Teeth

The Tsubaki 60BTL28 is a single-strand sprocket designed for power transmission systems using ANSI 60 roller chain. Its 28-tooth configuration suits machinery requiring a specific speed ratio or torque conversion in industrial drives.

Hardened Carbon Steel Construction

Manufactured from Grade 1045 steel with hardened teeth, the sprocket resists wear under repetitive loading. A black oxide finish adds corrosion resistance. The taper-lock hub accepts a 2012 bushing, allowing a secure shaft connection with a maximum bore of 2 inches and a hub projection of .791 inches.

Single Pitch 3/4 Inch Chain Compatibility

This sprocket works exclusively with single-pitch 60 chain at a 3/4 inch pitch. The pitch diameter measures 7.11 inches and the outside diameter is 7.107 inches. It does not accommodate multi-strand chains or different pitch sizes, limiting use to drives matching these exact chain specifications.

Questions about this item

What chain pitch does the 60BTL28 sprocket use and what does that limit?

The sprocket uses a 3/4 in chain pitch, which fixes the tooth spacing and limits it to ANSI 60 single-strand chain only.

Which taper-lock bushing does the 28-tooth sprocket require and what bore range does it cover?

It requires a 2012 taper-lock bushing, which accepts a bore from 1/2 in up to a maximum of 2 in.

How is the 60BTL28 sprocket installed and which step is commonly missed?

Slide the 2012 bushing into the sprocket, align the hub, torque the set screws to specification, then tighten the bushing cap screws in a star pattern — skipping the star sequence leaves the hub eccentric.
