TSUBAKI Top chain components
High-rotation return rollers, Guide flange
Use return rollers on the return way of the conveyor to support the top surface of the chain.
These rollers are effective in situations where damage to the top surface of the chain slats must be avoided, or to deaden noise on the return way of the chain.
Bearing types that suppress the occurrence of wear debris under dry conditions are also available.

Return roller installation examples
Disc Plates/Guide Flange
2 return rollers and spacers
Split-Hub Return Roller (with flange)
When the direction of travel between two strands of chain is backward, or their speeds are different
- Use PVC pipe or similar material instead of the spacer shown above to adjust the distance between return rollers when the plate width is greater than 83mm.
- Return rollers for stainless steel top chain will not rotate when combined with plastic chain, and may cause uneven wear of top plate surfaces.
- See illustration below for wide width Top Chain.
Notice: Curved frame end sections should not be in the inner side of the guide width.
