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.Heavy Duty 81XHH Roller Chain is manufactured for heavy-duty conveying applications that require a super high strength 81X series chain. It is the absolute strongest version of 81X chain on the market and boasts an extremely high 10sile strength, thick side-plates, quad-staked pins, and uses a solid bushing solid roller (SBR) design to ensure you are getting the best wear life out of this chain. Our 81XHH roller chain also implements heat-treated comp1nts such as the pins, bushings, side-plate, and rollers to further increase the working life and strength of the chain.
