DRIVE CHAINS - Tsubaki

Corrosion Resistant Roller ChainsStainless Steel Roller ChainsThese roller chains are made of stainless steel.SS SpecificationThese roller chains are made of 304 stainless steel (301 stainless steel clips). They offer greatercorrosion resistance than RS Roller Chains and RS Surface Treated Roller Chains, and can be usedin water and in corrosive atmospheres that are acidic or alkaline, as well as in low or hightemperatures (-20 to 400ßC). 304 stainless steel is only marginally magnetic. Some magnetismexists only due to the cold-forging process.NS SpecificationThese roller chains are made of 316 stainless steel (301 stainless steel clips on RS25NS, and 304stainless steel cotter pins on RS80NS). They are suited for applications that require higher corrosionresistance than SS chains. Except for the clips, they are non-magnetic.AS SpecificationThe pins and rollers of these roller chains are made of precipitation-hardened, tempered stainlesssteel, while the plates and bushes are 18-8SUS (304 stainless steel clips are 17-7SUS (301stainless steel)). They have a maximum allowable load that is 1.5 times that of SS chains. Corrosionresistance is slightly less than that of SS chains. AS chains are suited for applications that requirecorrosion resistance, heat resistance, and smaller sizes / higher kilowatt ratings than SS chains.Because of its precipitation-hardened stainless steel, the chains are magnetic.Surface Treated Roller ChainsThese are surface-treated RS Roller Chains.NP SpecificationThese chains are RS Roller Chains with nickel plating. The nickel plating not only improvesappearance, but also adds a small degree of corrosion resistance. Therefore, they can be used inapplications where there is exposure to water. Bear in mind when making your selection thatmaximum allowable load is approx. 15% lower than with RS Roller Chains.NEP SpecificationNEP Chain is a Coating chain with a high corrosion resistance thanks to its zinc coating base andtwo different kinds of special surface coatings for rollers and other parts. The zinc coating andspecial surface coatings protect the chain body from corrosive environments, giving it superior rustprevention. NEP Chain has superior anti-rust capabilities over previous WP or DP chains, reducingits load on the environment.APP SpecificationPins are treated with a non-strength degrading surface treatment to protect against pitting corrosionthat leads to fatigue breakage, making it highly effective in environments that readily promotecorrosion, such as outdoor or coastal applications. Safety precautions when using Surface Treated Drive ChainsDo not use NP / NEP specification Surface Treated Drive Chains if the chains will come in direct contact with food or where coatingflakes or wear dust can contaminate food. The specific gravity of flaked NEP film is lighter than water and will float.Also, in non-food applications, either appropriately cover the chains or contact Tsubaki about chain selection if usage is planned inenvironments where coating flakes and wear dust present problems. Though nickel is not subject to the Food Sanitation Law or theIndustrial Safety and Health Law, plating on sliding parts can flake.SSNSASNPNEPBefore Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling98
