Conveyor Rollers

The conveyor roller (idler) is the most numerous component of a belt conveyor and has a direct impact on its performance. A well-chosen, well-made roller reduces power consumption, extends belt life and prevents unplanned downtime.

What is a conveyor roller?

A conveyor roller is a rotating component made of a steel tube shell, a precision-machined shaft, bearing housings, bearings and seals. Rollers are mounted in idler frames to support the belt and its load on the carrying side and the empty belt on the return side.

Types of conveyor rollers we manufacture

• Carrying rollers: support the loaded top strand, arranged in 2-, 3- or 5-roll troughed sets.
• Return rollers: support the empty bottom strand in flat or V arrangements.
• Impact rollers: rubber rings absorb shocks at loading points and protect the belt.
• Rubber-lagged rollers: hot-vulcanised lagging resists wear and material build-up.
• Rubber-disc and spiral cleaning rollers: clean sticky material from the belt on the return side.
• Guide and sprocket rollers: for belt tracking and driven roller lines.

Manufacturing quality

We use precision welded steel tube, cold-drawn or ground shafts, sealed C3 clearance bearings and multi-labyrinth sealing. Every roller is checked for run-out, axial play and rotational resistance. Painted, galvanised or rubber-lagged finishes are available for dusty, wet and abrasive environments.

How to choose the right roller

Belt width, belt speed, bulk density and lump size of the material, idler spacing and the operating environment determine the right roller. High-capacity, high-speed conveyors generally need larger diameters and heavier bearings. Our engineers provide free technical support to match rollers to your existing line.

Standard range: Ø 63.5 – 219 mm diameter, 400 – 2400 mm belt width, Ø 20 – 60 mm shaft. Manufactured to DIN 15207, ISO 1537 and CEMA series or to your sample.
