What are light-duty conveyor rollers
Light and medium duty conveyor rollers are cylindrical elements mounted on a fixed axle with a built-in bearing (spring execution) or a threaded end for fixed mounting, used to build gravity or powered roller conveyors. Plastic rollers (PVC tube) are light, quiet and corrosion-resistant — suited for clean environments; metal rollers (galvanized or steel tube) handle heavier loads and higher speeds.
Nibora Ltd. keeps the full diameter range in stock — from the compact Ø30mm plastic version to the heavy-duty Ø60mm steel version — for conveyor lines from packaging machines to logistics sorting systems.

Frequently asked questions
What is the difference between a plastic and a metal roller?
Plastic rollers (PVC) are light, quiet and corrosion-resistant, suited for light loads; metal rollers (galvanized or steel) handle higher static and dynamic loads and higher speeds.
What shaft mounting options are available?
The axle is available fully spring-loaded (spring only, for floating mount in a profile) or with a threaded end (external thread) on the larger metal diameters, for fixed bolted mounting.
What is the price of a light-duty conveyor roller?
Contact Nibora Ltd. for a quote based on the selected diameter and length.
