Product Description

For applications where a single chain can support the torque and load comfortably, this single strand sprocket has only one set of teeth around the circumference

A chain with a size 40 chain has a pitch of 1/2 inch

An installed bore with a wide hub on one side that is ready to install

With a hub projection on one side to accommodate various types of bushings to help prevent slipping on the shaft, the Type B sprocket is somewhat larger than that of the Type A.

During manufacturing and assembly, the teeth of a sprocket are hardened either by electrical induction or by flame, extending its service life

Questions & Answers

What size bore does it have?

This one has a bore of 1". I will try to be as clear as possible.

1/4 inch key way or 5/16 inch key ?

The answer is yes

Can you tell me the size of the keyway?

It has a standard 1/4" keyway

What chain size does it fit?

There is a slight difference in width between 420 chain and 440 chain, but it should be fine. I would guess that it may have a higher likelihood of throwing a chain.
