We stock a full line of ANSI solitary 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 can supply sprockets with completed bores because of our fast-reaction in house industrial machine shop. Typically our sprockets are produced out of 304 grade stainless, but 316 as well as a few additional grades can be found upon request.
