TSUBAKI RS Series Roller Chain
The TSUBAKI RS series roller chain is a power transmission component used to link sprockets and transmit motion between parallel shafts. It is used in a wide variety of industrial machines, from conveyors to production equipment, and is a reliable solution for applications requiring synchronization and mechanical drive. MR Accesorios Industriales carries this line backed by more than 80 years in the Argentine market.
The RS series designation is read with the number indicating the pitch and the suffix defining the number of strands. For example, RS25-1 is a single-strand chain, RS25-2 is two-strand, RS25-3 is three-strand. Likewise, RS35-1, RS35-2, RS35-3 and RS35-4 correspond to single, double, triple and quadruple-strand chains respectively. The number after RS identifies the pitch size according to the ANSI standard, and the final numeric suffix indicates whether it is single, double, triple or quadruple. This nomenclature allows the chain configuration to be identified quickly.
In Argentine industry, TSUBAKI RS series roller chains are used in a wide variety of applications: packaging lines, belt and roller conveyors, machine tools, bakery equipment, lifting systems and drives in food and beverage plants. They are also present in the automotive, textile, woodworking and metallurgical industries. Their versatile design makes them suitable for environments with dust, moderate humidity and variable loads, provided the correct pitch and number of strands are selected.
To correctly select a roller chain, take into account the power to be transmitted, the rotation speed, the center distance and the type of lubrication. During assembly, check sprocket alignment and proper tension to avoid premature wear. Regular lubrication and sealing of the system are key to extending service life, especially in environments with contaminants. If the application demands greater strength, evaluate variants with special coatings or treatments, which can be checked by part number.
Roller chains are manufactured under ANSI standards, which facilitates interchangeability between different manufacturers that follow the same standard. When replacing a chain, it is important to verify the pitch, the number of strands and the type of end fittings. Although brands such as TSUBAKI offer recognized standards, it is always advisable to validate the critical dimensions against the original part number. MR Accesorios Industriales can advise you on the right equivalent for your equipment, with no guesswork.
