Conveyor rollers are the fundamental structures in a roller conveyor or on a stretch of rollers on a production line. They are the mechanisms that allow the movement of materials or components from one area to another.
By means of conveyor rollers, transport can be carried out on the same level, at several heights, on a slope, etc.; and they can be free‐moving, gravity‐moving or motorized. In the latter case, movement can be highly controlled by automating the system. Roller conveyors can be found in many companies and industries in many different sectors.
Actually, they are present in any industrial process in a chain or that requires the
displacement of materials or packages, from agri‐food companies (meat, fruit and vegetable, etc.), to pharmaceuticals, petrochemicals, the automobile industry, warehouses, logistics centers, in the packaging lines of any factory, product handling areas, etc.
A conveyor roller has three or four basic components:
1. The central structure or axis of rotation on which the rotation occurs. Depending on the application, we can produce them in PVC, aluminum, steel or stainless steel.
2. The outer cylinder, structure that surrounds the central axis. It is the surface on which the materials will move. They allow a large number of options to adapt to the type of material or elements that are going to move on them. From padded, tapered, with grip structures, etc. Steel with different finishes such as: zinc‐plated steel, galvanized steel, painted, etc.
3. The bearings are in the head. The head is the structure that anchors the roller in
position and allows its rotation. We can also find great diversity depending on its
application and load capacity. It is also the anchoring elements of the echanization
of the roller conveyor system.
4. The motorization and automation system (programming and movement control). The motorization and automation of movements through roller conveyors allows high control of movements and optimization of time.
Conveyor roller manufacturers can design and manufacture conveyor rollers for any
application we may need: load capacity, from light or heavy loads, transport speed,
automation, etc. adapting to all types of production systems or warehouse and stock
The purpose of conveyor rollers is to facilitate and speed up the transport of materials safely on the production line or between workstations. These movements can be performing by roller conveyor systems, as well as, in combination with other mechanisms such as belt conveyors.
Both goods movement systems have become of great importance today due to the constant increase in electronic commerce and online shopping.
