Our 60 roller chain sprockets are manufactured in accordance with ANSI B29 standards meaning that they directly interchange with other manufactures. What separates our 60-1 sprockets from others is the utilization of high-strength steel (1018 - 1045), hardened teeth on all sprockets up to 30 tooth-count, black oxide coating, and superb precision machining for optimal performance and contact between the sprocket and 60 roller chain. We have the widest selection of 60 chain sprockets out there, and if you don't see the specific sprocket you need to contact our customer support team and we will be happy to assist you!
