102.5 series engineer class sprockets are used for a wide verity of chain sizes. For cast sprockets, these sizes include A102B, S102B, C102B conveyor chain, SS102B, 6102B, ER102B, and SBS102B. These sprockets are typically supplied as cast material but we can also supply them as steel for longer operation. The below chart shows the standard tooth counts, as well as dimensions for each size.
