Double Plus Free Flow Chains

  • A free flow chain that allows for high speed conveyance at 2.5x the chain's speed thanks to a combination of small and large diameter rollers. Enables quiet accumulation as well.
  • We offer a line-up of Snap Cover Chains to prevent parts from falling into the frame.
  • Select from either engineering plastic or steel rollers to match your application needs.
  • In addition to our standard series, Tsubaki offers Lambda Series, hardened chrome plating, and Stainless Steel Series as well.

※1. Urethane lining available for RF2030VRP only.

※2. There is slight magnetism from plastic deformation during part processing and assembly. Contact a Tsubaki representative if absolutely no magnetism is required.


Roller (by need)
