08B 1-2-3 Chain Sprocket

Description

The term "08B 1-2-3 Chain Sprocket" refers to a specific type of sprocket that is designed to work with an 08B roller chain. Here's a breakdown of the terminologies:

"08B": This is the chain size or pitch designation. It indicates that the sprocket is compatible with an 08B roller chain, which has a pitch of 0.500 inches (12.7mm). The pitch refers to the distance between the centers of adjacent chain pins.

"1-2-3": This typically represents the number of teeth on the sprocket. In this case, it suggests that the sprocket has three different sections with varying tooth counts. For example, it might have one section with one tooth, another section with two teeth, and a third section with three teeth. This type of sprocket configuration can be used in applications where different speeds or ratios are required.

So, an "08B 1-2-3 Chain Sprocket" would be a sprocket specifically designed for use with an 08B roller chain, featuring multiple sections with different tooth counts.
