Designed and engineered for high speed/high tonnage
belts.
Designed to withstand the highest belt speeds achievable with heavy-duty impact rolls.
Slide-out/slide-in roller frames allow idler service without the need to raise belt or remove adjacent idlers.
Close roll spacing allows effective belt sealing and
superior belt support.
Innovative upper connector brackets link idlers together throughout the load zone, allowing them to work
together as a unified structure.
Elastomer bar suspension absorbs shocks from impact
maximizing the life of the belt support structure and
rolling components.
Accommodates belt widths and troughing angles for
CEMA, DIN, SABS and other conveyor standards.
Assemblies are supplied with impact rolls from Precision Pulley and Idler.
