The TSUBAKI RS-NS roller chain is a stainless steel transmission chain designed to work in corrosive environments where a standard chain would degrade quickly. It is used in equipment exposed to moisture, frequent washdowns or chemical vapors, and maintains the standardized geometry and pitch of the ANSI system. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, and advises you on choosing the correct pitch and configuration.

The series designation combines the ANSI pitch number with the suffix NS, which identifies the stainless steel version for corrosive environments. Thus, RS25-NS is the smallest pitch in the series and RS80-NS the largest. The number does not indicate measurements in millimeters: it is the ANSI pitch code, and each one corresponds to rollers, plates and pins of standardized dimensions. To order the correct chain, provide the full part number exactly as it appears on the equipment or drawing.

These chains are found in food and beverage plants, industrial washdown areas, surface treatment, chemical plants and cold storage facilities, where water, detergents or vapors attack carbon steel. They are also used in outdoor equipment or in coastal areas. In Argentina, they are commonly found in packaging lines, washdown conveyors and machines that are cleaned with pressurized water. Corrosion resistance extends service life and reduces downtime for replacement.

To select correctly, consider the pitch, the number of strands and the length in number of links. Verify that the sprockets are compatible with the ANSI pitch and that the sprocket material is suitable for the corrosive environment. 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 product recommended for stainless steel and regularly check roller and pin wear.

ANSI roller chains are interchangeable between manufacturers if the pitch, number of strands and standardized dimensions match. The suffix NS is specific to TSUBAKI for its stainless line, so when looking for an equivalent in another brand, you must request a stainless steel chain of the same ANSI pitch. Not all brands use the same nomenclature to identify the material, so it is advisable to compare the technical data sheet and not just the part number.

If you need to replace a TSUBAKI RS-NS chain, send the full part number, the number of links or the length, and a photo of the sprocket if you have one, via WhatsApp. At MR Accesorios Industriales we will reply shortly with the alternative that fits your equipment. We can also help you determine the pitch if the original part number is no longer legible.
