CEMA D Rubber Discs Return Idlers

Heavy-duty rubber disc return idlers with 5" and 6" diameters, designed to CEMA D standards for reliable belt cleaning and support.

Product Overview

ZOOMRY CEMA D Rubber Discs Return Idlers are heavy-duty conveyor components designed for the return side of belt conveyors, featuring rubber discs that provide effective belt cleaning, reduced material build-up, and extended belt life. Manufactured to CEMA D standards, these idlers deliver exceptional durability and performance in demanding mining, quarrying, and bulk material handling applications.

The rubber disc design – with discs spaced along the roller – provides self-cleaning action that prevents material carry-back and reduces belt wear. Available in 5" and 6" diameters, these idlers offer superior load capacity and impact resistance for heavy-duty return side applications. With robust construction, advanced sealing systems, and precision-engineered components, ZOOMRY CEMA D Rubber Discs Return Idlers are built to withstand harsh operating environments.
