16B-1 hardened hub sprockets

16B-1 hardened hub sprockets are simplex sprockets for 16B-1 chain of 1" (25.4 mm) pitch to DIN 8187 / ISO 606, with induction-hardened teeth. They work as driving sprockets in heavy conveyors and agricultural machinery.

A hardened 16B-1 sprocket protects the chain from elongation

A hardened driving sprocket wears more slowly, so it protects the chain from elongation for longer and you stop the machine for replacement less often. The C45 steel hub remains unhardened and can be machined freely.

16B-1 simplex driving sprockets with 45-55 HRC teeth

16B-1 simplex sprockets in C45 steel with teeth hardened to 45-55 HRC, in a choice of tooth counts typical of driving sprockets. Dimensions are given on the product page, and sprockets with unhardened teeth and with a finished bore can be found in the Hub sprockets and Finished bore sprockets groups.

Frequently asked questions about 16B-1 hardened sprockets

Does a hardened sprocket need machining before installation?

Yes - just like a standard hub sprocket. You bore out the pilot bore for the shaft and then cut a keyway.
