The TSUBAKI NEP series roller chain is a power transmission chain designed to work in corrosive environments, where humidity, frequent washdowns or chemical agents accelerate the wear of a conventional chain. It is used in equipment that requires reliable mechanical transmission and low maintenance, and MR Accesorios Industriales sells it in Buenos Aires, Argentina, with technical advice to choose the right pitch and configuration.

The NEP series designation is read in parts. The number that follows the letters RS indicates the chain pitch according to the ANSI standard: for example, RS35-NEP-1 corresponds to pitch 35, RS40-NEP-1 to pitch 40, and so on according to the part number. The letters NEP identify the version for corrosive environments, and the final number indicates the number of strands: 1 for single, 2 for double. With those three pieces of information — pitch, treatment and number of strands — you can already identify the chain you need.

These chains are used in industries where washdown and corrosion are part of the process: food and beverage plants, meatpacking plants, industrial wash bays, surface treatment and high-humidity environments. They are also used in equipment exposed to the weather or to chemical vapors, where a standard chain rusts and fails prematurely. In Argentina, MR Accesorios Industriales sells them for maintenance and replacement in production lines, conveyors and machines that operate under those conditions.

To select the right chain, take into account the pitch, the number of strands and the type of sprocket it will mesh with. The NEP series is designed to resist corrosion, but installation is still key: verify sprocket alignment, proper tension and the recommended lubrication for each application. If the environment is very aggressive, it is also advisable to check the sealing and the inspection frequency. A well-installed and lubricated chain lasts much longer, even under severe conditions.

As for equivalents, ANSI roller chains are identified by their pitch and number of strands, which allows comparison between manufacturers. The TSUBAKI NEP series stands out for its treatment for corrosive environments, so when looking for a replacement it is not enough for the pitch to match: you must verify that the chain offered has equivalent protection. If you have doubts, send us the full part number and the type of working environment, and we will help you find the right option.
