Our belt conveyor idlers is produced for bulk material conveyors used in mines, sand plants, cement lines, ports and storage yards. The roller shell is normally made from steel pipe, with sealed bearings pressed into both ends and a straight shaft running through the center. We keep the structure simple because maintenance teams usually want parts that can be removed, checked and installed again without special tools. For this type, common diameters are 89 mm, 108 mm, 133 mm and 159 mm. Length is usually selected from 200 mm to 1600 mm depending on belt width and frame spacing. Shell thickness is often 3.0 mm to 4.5 mm for normal duty lines, while heavier jobs can be discussed by drawing. The bearing options include 6204, 6205 and 6305 sealed types. Painted steel is used for many indoor projects; galvanized finish or rubber ring design can be used when moisture or sticky material is a problem.
