ANSI SS Chain

All basic components of this chain are made of Stainless Steel SUS304 (except the spring clips, which are made of SUS301). This chain can be used in special environments such as underwater, acidic and alkaline applications. It can also be used in high and low temperatures (-20°C to +400°C).
SUS304 is only marginally magnetic, due to the cold-forging process. For details on corrosion resistance, please check out our Corrosion Resistance Guide.

  • RS11-SS to RS35-SS are rollerless chain (only bush). The figure shown is the bush diameter.
  • Connecting links are clip type for sizes RS11-SS to RS60-SS, and cotter type for sizes RS80-SS to RS100-SS.
  • The rivet-type for single-strand and multi-strand chain above RS80-SS is quad-rivet.
  • For details on corrosion resistance selection, please consult our Corrosion Resistance Guide.
  • Larger chain sizes are available on request.
