We stock a full line of ANSI single 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. However, we can supply sprockets with finished bores thanks to our fast-reaction in house industrial machine shop. Typically our sprockets are manufactured out of 304 grade stainless steel, but 316 as well as a few other grades are available upon request.
