Double Pitch sprocket  Standard series (Pilot bore)

Product photo
  • Can bring out the full performance of Double Pitch Chain.
  • The shaft hole is the pilot bore, and so will require finishing before use.
  • *For S rollers, when the number of actual teeth is more than 30T use a standard RS sprocket.

Features

Steel type

  • *Conforms to JIS standards, with quick delivery of sizes/teeth numbers used often.
  • *Uses carbon steel for machine structural use, and both hardened teeth and unhardened teeth specifications are available.
  • *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.
  • *[Available chain sizes ] S-roller :RF2040~RF2160, R-roller :RF2040~RF2100

Stainless steel type

  • *Uses austenitic stainless steel with excellent corrosion resistance and can withstand high temperatures, so it finds use in high and low temperature environments.
  • *[Available chain sizes ] S-roller :RF2040~RF2160, R-roller :RF2040~RF2080
  • Stainless steel Wear-resistant series can also be manufactured. Contact us for details.
  • *[Applicable chain size for wear-resistant series ] S-roller :RF2040~RF2080, R-roller :RF2040~RF2080

Engineering Plastic Type

  • *Engineering plastic sprockets use a nylon-based plastic and can be used with no additional lubrication.
  • *[Available chain sizes ] S-roller :RF2040~RF2060

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
