The TSUBAKI RS B-NP roller chain is a metric-pitch transmission chain according to BS standard, manufactured with materials and treatments that resist corrosion. It is used where humidity, frequent washdowns or chemical agents degrade a conventional chain. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, with technical advice to choose the correct pitch and number of strands.

The designation of the RS B-NP series reads as follows: RS identifies the TSUBAKI roller chain line; the number that follows —08, 10, 12— indicates the pitch according to BS standard; B corresponds to that British standard; NP indicates the version with anti-corrosion protection; and the last digit —1, 2 or 3— indicates whether the chain is single, double or triple strand. For example, RS08B-NP-1 is single, RS08B-NP-2 is double and RS10B-NP-3 is triple. The complete code defines pitch, standard and number of strands.

These chains are used in industries where washdown and humidity are constant: food and beverage plants, meat processing plants, industrial laundries, surface treatment, paper mills and water treatment plants. Also in equipment exposed to the weather or chemical vapors, such as conveyors, elevators, packaging machines and drive systems in sheds with condensation. In Argentina they are seen in production lines that are cleaned daily with water or detergents.

To select the chain, start from the pitch required by the sprocket and define the number of strands according to the load and available width. Verify that the sprocket is compatible with the BS standard and the corresponding pitch. During installation, check shaft alignment and tension: a chain that is too tight accelerates wear and one that is too loose jumps. Lubricate with the appropriate product for humid environments and check the sealing or anti-corrosion protection according to the degree of exposure.

Roller chains are identified by standard, pitch and number of strands. When comparing brands, the pitch alone is not enough: verify that the standard (BS, ANSI or other), the roller diameter and the inner width match. A chain from another brand with the same pitch may not be interchangeable if the roller or width differ. For replacements, the safest approach is to compare the complete code and the critical dimensions before mounting.

If you need a chain for equipment working in a corrosive environment, send the code or model by WhatsApp to MR Accesorios Industriales. With that data the series, pitch and number of strands are identified, and we respond promptly.
