Nitro® Sprockets & Hubs

Sprockets are a toothed wheel that works in conjunction with roller chain to power all types of machinery. Roller chain sprockets come in many different types, tooth counts and bore sizes to accommodate various drive configurations. We stock an extensive range of finished bore sprockets, type A sprockets, idler sprockets & weld on sprockets. All Nitro® sprockets are manufactured from 1045CD (cold drawn) carbon steel with hardened teeth for better wear resistance. All sprocket types fully conform to the ANSI B29.1 standards to ensure compatibly with ANSI roller chain. MTO (Made-to-order) sprockets are available by quotation for OEM's, aftermarket suppliers, OEM's and resellers.

You can view our easy-to-use sprocket diameter chart to find the tooth count by chain size for the diameter required.

Sprocket Types

We offer a large selection of different sprockets types that's available in a wide range of tooth counts, chains sizes and configurations.

Type BS Sprocket or Type B Sprocket

These are by far the most common sprocket used in chain & sprocket driven machines. The sprockets are bored to size and include a keyway & 2 setscrews for attaching to a shaft.

Type A Sprocket

Mostly used for machining in bolt holes or to weld directly onto a shaft. These are commonly called "plate sprockets".

Type BB Sprocket

Free-wheel sprocket for taking up slack in chain drives that use long lengths of chain.

Type X Weld On Sprocket

These are universal sprockets that allow you to essentially "Build-a-sprocket" by welding in a weld-on-hub that is available in wide range of bore configuration and sizes.
