When a drive or conveyor runs in a wet, chemical or washdown-heavy area, a standard carbon steel chain can rust and shed particles onto the product. The TSUBAKI SS series is a stainless steel roller chain built for exactly those conditions, and it is common in food, chemical and pharmaceutical plants. MR Industrial Accessories supplies this line and helps you match pitch, strand count and length to the equipment you are running.

Reading the code is the fastest way to identify a chain. RS points to an ANSI pitch roller chain. The digits after RS give the pitch: RS40 is 1/2 in, RS50 is 5/8 in. The SS suffix tells you the chain is stainless steel. The final digit is the strand count, so 1 means single and 2 means double. RS40-SS-1 is therefore a 1/2 in pitch stainless single-strand chain, while RS40-SS-2 is the two-strand version.

You will see these chains on packaging lines, industrial washers, cooling tunnels, bottle conveyors and food processing equipment. Chemical plants also use them where steam, mild acids or high-pressure cleaning are present. Because the material resists corrosion, the chain tends to last longer than carbon steel in these areas, which would otherwise rust and contaminate the product.

Selection comes down to pitch, number of strands and overall length. Check that your sprockets match the ANSI pitch and are not worn, since a worn sprocket will speed up chain wear. Lubrication matters too: in corrosive settings, use a lubricant rated for food contact or choose a self-lubricating chain. Confirm shaft alignment and tension, because a misaligned or loose chain will fail sooner. If washdowns are frequent, the SS series is the logical first choice.

TSUBAKI SS chains interchange with other ANSI-pitch chains in terms of pitch and dimensions. For a replacement, compare pitch, inner width and roller diameter. The original code often matches the RS designation. If you are unsure, send a photo or the code stamped on the plate and we will help identify the equivalent.
