Double Plus Conveyor Chain

Product photo
  • Chain for conveyance and accumulation.
  • During transportation, a frictional force between large and small diameter roller causes both to rotate identically, and a ratio of roller diameters cause a speed of conveyed object to be 2.3 times a chain speed.
  • As there is a braking force acting on a large diameter roller, slip occurs between large and small diameter rollers, allowing for free flow conveyance.

Features

  • ・Energy savings, lower costs

    Small coefficient of friction means low required horsepower, reducing a chain size required and costs.

  • ・Longevity

    Chain speed is 1/2.3, and a chain can handle a large roller allowable load, giving a chain over twice life of Top Roller Chain.

  • ・Stable running

    Height from rail to conveyed goods is low, allowing for stable running.

※Maximum allowable load is a value calculated based on Tsubaki in-house standards and is calculated strength. As long as there are no other constraints, maximum allowable load is used in selecting large size conveyor chain.
This value will differ by manufacturer and is not a guaranteed value.

※Contact a Tsubaki representative regarding average tensile strength.
