  • Free Flow Large Size Conveyor Chain

Outboard Roller Conveyor Chain

This chain features an outboard roller on the S roller of a base conveyor chain.

The sprocket engages the center S rollers, while the outboard rollers handle running to provide for smooth operation.

Base conveyor chain is available in any series.

Conveyor Chain with Outboard Rollers

1. Applications

  • For special attachments on the plates. (Fig. 1)
  • For when supporting loads on the center S rollers is difficult.
  • For when installing a guide on the chain's return side is difficult.
  • For giving double plus and accumulation capabilities to R roller outboard rollers. (Fig. 2)
