U.S. TSUBAKI TOP CHAIN
RS Plastic Chain Standard Series RS Plastic chain consists of polyacetal chain links and 304 stainless steel pins and operates with standard roller chain sprockets. Based on power transmission roller chain, U.S. Tsubaki RS-type has a flat top side for power transmission or conveying use. “E” Series (Electro-Conductive Series) The special plastic used in the “E” series is electro conductive and permits electrical charge. These chains are suitable for applications where there is electric noise, electric sparks, or where dust collects due to static electricity. Volume resistivity: 10 6 •cm “Y” & “SY” Series (Anti-Chemical Series) The amazing “Y” & “SY” series utilizes an engineering plastic which permits the chain to perform well even where chloride, acid, alkaline, oxidizers and most organic solvents are present. “SY” series is a combination of “Y” series plastic block links and titanium pins and performs well even when exposed to sulfuric and hydrochloric acid. “K” Series (Heat Resistant Series) The U.S. Tsubaki “K” series is made of a resilient new engineering plastic which can withstand environments where temperatures reach 284°F. In contrast to plastic chains made of conventional plastic, this chain will not lose its valuable properties at high temperatures.
