Collectible 14-Tooth Split-Taper Sprocket

The Tritan 40BTL14H is a new, steel roller-chain sprocket with 14 hardened teeth finished in black oxide. It is sized for ANSI 40 chain with a 1/2 inch pitch and fits a 1008 split-taper bushing. The piece meets ANSI B29.1 and BIS standards and is listed under sporting memorabilia and collectibles.

Chain Pitch and Bushing Constraints

The sprocket only works with 1/2 inch pitch chain and a 1008 split-taper bushing, limiting it to drives that match those exact dimensions. Maximum bore is 1 inch, hub diameter is 1 13/16 inches and hub projection is 0.591 inches, so shaft and spacing must align with these figures. Tooth width of 0.284 inches and a 7/8 inch length through bore further restrict interchangeability with other chain sizes or bushing types.

Installation Notes and Common Issues

Mount the sprocket onto the 1008 split-taper bushing, then secure the assembly to the shaft with the bushing hardware. Hardened teeth resist wear but require accurate chain alignment to prevent premature noise or uneven loading. The single-strand design and one-side hub projection mean offset or multi-strand setups will not fit, and the black-oxide finish offers limited corrosion protection in harsh environments.

Questions about this item

Should I choose the 14-tooth sprocket or a different tooth count for my #40 chain?

The 14-tooth design matches #40 chain with 1/2 in pitch; verify your speed ratio and centre distance before selecting a different tooth count.

What does the 2.247 in pitch diameter mean once the sprocket is mounted on a shaft?

It sets the effective driving radius for the #40 chain, so chain speed equals shaft RPM multiplied by 2.247 in divided by 2.

Which bushing standard does the split-taper 1008 interface follow, and what bore does it cap?

The 1008 split-taper bushing fits a maximum 1 in bore and conforms to ANSI B 29.1 dimensions.
