We stock a full line of ANSI one strand 304-grade stainless steel sprockets both as A-Plate style and B-Hub style. We keep these on the shelf as standard stock bores. Nevertheless, we are able to supply sprockets with finished bores thanks to our fast-reaction in house industrial machine store. Typically our sprockets are produced out of 304 grade stainless steel, but 316 in addition to a few other chain sprocket grades are available upon request.
