F40B21 Standard single-strand roller chain, standardized by ASME, is an assembly of alternating pin links and roller links. The distance between pin centers is called the pitch. The pitch is what categorizes the size of the chain. The larger the pitch, the higher the load rating. Chains with small pitches carry smaller loads, operate more quietly, and at higher speeds. Multi-strand, small-pitch roller chains are a good solution for high-load, high-speed applications.More importantly, we make special parts according to supplied drawings/samples and warmly welcome OEM inquiries. Although we take pride in being “Collar Specialists”, our expertise in sourcing quality products has made Lucas Industrial a valued supplier of other power transmission products as well. First among these are linear bearings with interchanges available for virtually all styles and sizes.
