High-rotation return rollers, Guide flange

These return rollers use an engineering plastic having low resistance to the shaft on the inner circumference.

Use the high rotational speed return roller as a support on the upper surface of the chain at the conveyor return side.
Roller rotation reduces sliding resistance and reduces scratches on the top surface of the chain.
Engineering plastic materials with small resistance to the shaft are used on the inner circumference, and soft materials with large resistance to the chain are used on the outer circumference, making them extremely rotatable.It is also effective for preventing scratches on the top surface of the chain and for softening noise on the conveyor return side.

  • 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. Return roller installation examples4 Notice: Curved frame end sections should not be in the inner side of the guide width.
