Roller Chain - Tsubaki

British Standard/DINRoller ChainDrive ChainIntroduction to Tsubaki British Standard/DIN Roller ChainTsubaki British Standard/DIN roller chains are manufactured to the following standards: International Standards Organization(ISO 606), British Standards Institution (BS 228) and Deutsches Institut für Normung (DIN 8187).Tsubaki produces British Standard/DIN roller chain in a variety of sizes (now including RS05B and RS48B) and materials(carbon steel, lube-free Lambda, stainless steel and nickel plated). These chains are ideal for use on equipment that has beenimported into Canada or on new machinery that is made in Canada but destined for export.Features of Tsubaki British Standard/DIN roller chain include:• Easy disassembly (cutting) on sizes RS08B to RS16B. Users can easily extract the pin on-site, with a standard screwtype chain cutter.• Ring coining - a process unique to Tsubaki whereby the connecting link is made as strong as the rest of the links in thechain. The ring coining process creates plastic deformation around the pinhole on the link plates of the chain. Thisgenerates residual stress around the deformed area, which boosts the transmission capacity of the connecting links to thesame level as the chain itself.• Solid rollers, bushes and link plates, all of which are shot-peened - a process that work hardens the surface of thesecomponents, improving their durability at high speed and increasing fatigue strength.• Center sink design of the rivet head - the result of years of experience in manufacturing marine diesel chain atTsubaki. The benefit of the center sink pin design is that notches on the rivet head indicate line of riveting and easyidentification in the case of pin rotation caused by overload conditions.• Wider link plate design - improving the fatigue strength.• Chain is pre-stressed after manufacture to ensure that all components are properly seated. This reduces the need forinitial chain adjustment and has also improved the length tolerance.A-61
