Sprockets come in a wide range of types and sizes for many roller chain sizes. Most Nitro sprockets are manufactured from 1045CD (Cold Drawn) carbon steel with hardened teeth & black oxide finish.
These chain sprockets are the most commonly used sprockets in the power transmission industry. Finished bore sprockets are usually referred to as "Type B Sprocket" or "Type BS Sprocket". B Type sprockets have a hub one one side of the sprocket.
The finished bore sprocket is already bored to size with a keyway & 2 setscrews.
The plate sprockets are a flat (hubless) sprocket that's known as a "Type A Sprocket". These sprockets are mainly used for machining in bolt holes or slots for attaching to a drive.
Idler sprockets are perfect for taking up slack where long lengths of roller chain is used. The idler sprocket is called "Type BB" in the chain and sprocket industry.
Weld on sprockets & hubs are a universal option to essentially "build-a-sprocket". Simply select a sprocket & hub, then weld them together. All of our weld on sprockets are an "X Series", so these are compatible with any X series hub.
Our X series hubs are available in finished, splined, hex or square bores. These hubs work with any X series sprocket or pulley.
