  • RS11SS Ultra Miniature Chains

    U.S. Tsubaki Miniature chain RS11SS is made of 304 stainless steel throughout. This provides superior corrosion resistance and high temperature resistance. The chain is specially designed for use where space is extremely limited, such as in communications equipment, business machines and electro-mechanical devices.

  • RS15 Ultra Miniature Chains

    U.S. Tsubaki RS15 bushed chain is between RS25 and RS11SS in size and is economical for compact applications.

    • Strong and precise, this chain is based on RS roller chain production technology.
    • Lightweight and compact, it is only half the weight of RS25 which is the smallest ASME/ANSI roller chain.
    • All parts are heat-treated for better strength and wear resistance.
    • Suitable for industrial data equipment, business machines, electric and electronic equipment, medical instruments, photographic equipment and other devices.
