  • ColorTransparent
  • 13-tooth steel sprocket for precise chain engagement

Finished-bore sprocket for #35 chain

This 13-tooth steel sprocket fits a 5/8 in bore and accepts single-strand #35 chain with 3/8 in pitch. It arrives new with a black-oxide finish, two set screws and a 3/16 in wide by 3/32 in deep keyway already machined.

Build integration: shaft mounting

The fixed 5/8 in bore locks onto a matching shaft using the supplied set screws and keyway, so no additional boring or bushings are required. A 1 1/4 in hub diameter and 0.582 in projection keep the assembly compact, while the 1.75 in outside diameter clears adjacent structure in tight drivetrain layouts.

Upgrade context: replacing worn

Swapping a worn sprocket with this finished-bore unit restores accurate pitch engagement on #35 chain without re-machining the shaft. The jump is worth it when the existing sprocket shows tooth hooking or when a plain-bore version would need custom keyway work before installation.

Questions about this item

How many teeth does the 35BS13H sprocket have before chain wear becomes the limiting factor?

The sprocket has 13 teeth and a pitch diameter of 1.567 in, so chain stretch will be the first limit under sustained use.

Does the black-oxide steel sprocket run hot or noisy when driven continuously?

Steel construction and black-oxide finish dissipate heat well; no bearings or lubrication points are included, so noise stays low in normal operation.

What shaft size and keyway dimensions must already be on the machine for this sprocket to fit?

A 5/8 in shaft with a 3/16 in wide by 3/32 in deep keyway is required, and two set screws secure the hub.
