Sideflexing MatTop
Chains
The sideflexing belts range exists of ½-inch pitch 505, 1¼-inch pitch 1200 and 1¼-inch pitch 7956 belts, offering a solution
for almost any curved application. As a standard the belts are supplied in low friction acetal for beverage, in acetal or
polypropylene.
Features
•
In compliance with the industry standards, three curve guiding systems are offered:
RBP uses beveled Positrack lugs underneath the
belt to guide the belt in the curve. The lugs run
against a beveled strip, retaining the belt in the
curve. This system enables easy removal of the belt
from the conveyor for cleaning or maintenance. The
conveyed product can be wider than the belt width
as there is no wearstrip on top of the belt to hold
it down.
RBT guiding uses Tabs underneath the belt to hold
the belt down while running through the curve.
Often the tabs can also be used to hang the belt in
the return part of the conveyor. Depending on the
construction chains MatTop with tabs are more
dif²cuLt to remove from the conveyor for cLeaning
and maintenance.
RB (FLat beLt without Tabs or Positrack) is suitabLe
for the conventionaL guiding method, supporting
the beLt on its inner radius. The beLt is heLd down
in the curve by a wearstrip on top of the beLt or by
running through a U-channeL.
This method can aLso be appLied in the return part.
In this way it is dif²cuLt to remove the beLt from the
conveyor. The RB executions are aLso suitabLe for
Low-tension spiraL appLications.
•
BeLt and curve guiding materiaLs have a PV (Pressure/VeLocity)-Limit determining the maximum speed or Load in a speci²c appLication. Rexnords caLcuLation software
and engineering manuaLs wiLL advise concerning the feasibiLity of a speci²c appLication. For spiraL appLications it is recommended to discuss with a quaLi²ed OEM
retro²t or design detaiLs, to avoid overLoad issues or faiLures.
