RS® Roller Chain

A roller chain series with significantly improved kW ratings capacity and enhanced performance relative to chain size and application.



BS / DIN Roller Chain

BS/DIN standard roller chain that conforms to ISO 'B'(ISO606-1994(E))

  • All dimensions differ from that of ANSI and JIS standard roller chain
    except for the chain pitch.
  • Special sprockets are also available.



  • Lambda Chain

    The best product for long-life without lubrication.Further upgraded through improved bushings.Twice the wear life compared to conventional specifications.
    (More than 14 times the wear life of standard RS® Roller chain for sizes up to RS100)

    Can be used within a temperature range of -10°C to +150°C (+14°F to +302°F)



    SUPER Roller Chain

    Compared to RS Roller Chain, kilowatt ratings, allowable load, and tensile strength are all greater, enabling the use of a chain 1 to 2 sizes smaller.



    Stainless Steel Roller Chain (SS)

    Roller chain made of SUS304 stainless steel (clips are SUS301). It offers greater corrosion resistance than RS® Roller Chain, NP Roller Chain and WP Roller Chain.
    It can be used in water, acid, alkaline, and other corrosive environments as well as in a wide range of temperatures (-20°C to +400°C (-4°F to +752°F)).
    Although SUS304 stainless steel has almost no magnetic properties, Stainless Steel Roller Chain (SS) is manufactured using cold forming, which causes a weak level of magnetism to exist.



    Small Pitch Conveyor Chains

    Most popular general purpose chain within the attachment chain series.
    All parts are made of steel and have been hardened through a state-of-the-art heat treatment process.
    Wide variety of attachments to choose from.
    Please specify attachment type and spacing.



    Large Pitch Conveyor Chains

    Economical general purpose chain.
    Pins and bushings hardened through a state-of-the-art heat treatment process.
    Chain sizes available in metric and imperial.
    Wide variety of attachments to choose from.



    Flexible Coupling : Jaw-Flex Coupling

    No lubrication, non-backlash and high torsional stiffness coupling makes full use of the characteristics of servomotor.
