Specialty large size conveyor chain  FB Series

Product photo
  • Uses a solid lubricant and seal structure to give a chain more than twice wear life over previous products.
  • Ideal for preventing chain elongation in bucket elevators and flow conveyors.

Structure & Features

  • ・Solid lubricant minimized pitch elongation
  • ・Seal structure keeps conveyed material out from between pins and bushes
  • ・Seal structure prevents solid lubricant from escaping
  • ・Quieter (on average 2dB quieter)
  • ・Operating Ambient Temperature :-15℃~200℃
  • ※Seal structure may change depending on an operating temperature.
  • ※Be aware that FB Series is effective against chain wear elongation, but not against roller play and other forms of bush–roller wear.

※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.
