Drive sprocket  Standard series (Pilot bore)

Product photo
  • RS Sprockets are optimal for G8 Series RS Roller Chain.
  • These sprockets are for general use roller chains (JIS/ISO standards), with an extensive line-up of standardized products.
  • Available in steel types (unhardened/hardened teeth specifications), TOUGH TOOTH Sprockets optimized for Heavy Duty Chain, stainless steel types, and plastic types.

Features and Products line-up

Choose from a wide range of lineups according to your application.

  • *Steel type :
    General use type. Hardened teeth specification with improved wear resistance is also available.
  • TOUGH TOOTH
    Improved strength and durability, mainly for Heavy Duty drive chain.
  • *Stainless steel type :
    Mainly used with stainless steel chain. "Wear-resistant series" which use stainless steel with excellent corrosion resistance and improved wear performance are also available.
    Note )Use surface-treated sprockets for coating chains.
  • *Engineering Plastic Type :
    Made of nylon-based plastic for lubrication-free operation. Suitable for light load applications.
  • *Surface treatment type (MTO items) :
    Black oxide, electroless nickel-phosphorus plating, and electro galvanizing (trivalent chromate treatment) can be selected according to the required corrosion resistance.
  • Sprockets with Shaft
    We manufacture the sprocket together with the shaft and deliver them as a set.

  • ・hardened teeth specifications

    We recommend sprockets with hardened teeth when tooth strength and wear resistance need to be increased.
    The machined hub made of machine structural carbon steel with a small number of teeth in each size and the single dual type (SD) have hardened teeth.

Sprocket Stainless steel type Wear-resistant series

Sprocket  Stainless steel type  Wear-resistant series
  • ・Recommended sprocket for Stainless steel chain HS series.
  • ・Improved wear resistance compared to stainless steel sprocket.
  • ・Suitable not only for Stainless steel chain HS series but also for SS series and others which wear life is desired.
    *Surface-treated and has a longer life than stainless steel sprockets. (From in-house test results)
    *Corrosion resistance is equivalent to that of stainless sprocket.
  • ・Applicable size :RS40~RS80, RF2040~RF2080
  • ・Please consult us for details.

Sprockets with Shaft

  • ・No need to assemble the shaft into the sprocket.
  • ・No need to inspect the shaft upon receipt. We can also provide an inspection report with the inspection results. (Separate fee required. )
  • ・Can be attached as-is to your equipment after receipt. (Bearings and the like can also be included in the assembly upon request. )
  • ・Sprocket and shaft are sourced from the same supplier, which can reduce management man-hour compared to ordering from separate suppliers.

Comparison of time needed to install in equipment

Comparison of time needed to install in equipment

There is no need to assemble the shaft into the sprocket, saving 30 to 35% in mounting time.

Package

  • ・Available for Lock Sprockets as well.
  • ・Phasing and other assembly conditions available.
  • ・Contact a Tsubaki representative for more information.

Note) When selecting sprocket specifications

・It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used. For details, please refer to the compatibility table for each chain and sprocket.

・Shaft bore remains as a pilot bore, so it must be machined by the customer before use. Click here if you require a product with a finished bore

Construction A Type B type C type SD Type
Multi-strand Heavy Duty Chain (Super-H, RS-HT, etc.)  Note 1 For using two single-strand chains at the same time
HB type HC type
Usage by structure Used when mounting on a rotating body, such as the center member of Torque Limiter. Most versatile use. For use with large driven sprockets or when key surface pressure is insufficient with B type. For using two single-strand chains at the same time.

Notes
 1.The total tooth width (transverse pitch) of multi-strand Heavy Duty chains (HB/HC types) differs from the standard.
