CEMA E Rubber Disc Return Idler

Product Overview

The CEMA E Rubber Disc Return Idler carries spaced rubber discs larger than the shell with open gaps between them, so sticky coal, clay and overburden peel off as the roller turns rather than building into a lumpy, unbalanced drum. This self-cleaning action keeps the return belt flat and reduces carry-back to the tail pulley on 36–96 inch mining and wet-application spans. The discs cushion the belt while the steel core and sealed bearings maintain CEMA E load capacity.

How to Choose This Component

Grade and load: choose CEMA E for extra-heavy, high-tonnage and overland duty; CEMA D for heavy-duty mainstream sections. Size the roller diameter and bracket spacing to the expected impact, belt load and material flow.
Belt width: match the part to your belt (BW 36"–96"). When requesting a quote, send belt width, required trough angle or drum diameter, and installation spacing so we can confirm a drop-in fit.
Working environment: tell us whether the duty is wet, dusty, sticky, abrasive or high-drop so we can match the seal, lagging, material and surface finish.
Retrofit and mounting: provide existing bracket spacing and frame type for a direct replacement; painted or galvanized finishes are both available.
