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.
