Rollers and supports for conveyor belts

When it comes to a conveyor belt system, rollers represent a significant portion of the overall investment required for its implementation. It is therefore of paramount importance to make a careful selection of the rollers to be installed and to verify that they are suitable for the belt's use, made with precise workmanship and selected materials. Only in this way is it possible to achieve the high quality of the roller that guarantees an operational life suitable for the plant, thus avoiding unnecessary and economically damaging plant downtime.

The choice of rollers

The choice of roller type should take into account the following factors:

  • Abrasiveness and corrosiveness characteristics of the material being transported.
  • Environmental and working conditions of the plant where the rollers will be installed.

Abrasive materials such as clays, granites, and iron minerals may necessitate the selection of heavier-duty roller series, favoring a larger diameter of the roller tube as this results in less contact between the roller surface and the belt itself. For plants transporting corrosive materials such as salts, chemicals, etc., it's imperative to choose protected rollers or rollers constructed with appropriate materials that are resistant to these substances over time. Rollers can be made of steel, coated with multiple layers of paint according to specific cycles, or coated with rubber or other anti-corrosive materials. Alternatively, they can be entirely constructed from corrosion-resistant plastic materials. Environmental conditions with high levels of dust (transporting cement, limestone, ashes) require the use of rollers from series with sealing systems that offer the highest degree of possible protection.


The range of rollers

The Global Nastri range for conveyor belt transport consists of:

  • Idler rollers in steel and PVC – used for supporting the belt
  • Rollers with anti-adhesion rubber rings, rubber spirals, and steel – used for belt cleaning
  • Guide rollers and centering rollers – used to prevent belt deviation and shifting from its correct position
  • Impact rollers with rubber rings and impact bars inserted at the material drop point on the belt to cushion the impact
  • Drive drums, custom-built according to customer requirements and coated with diamond-pattern rubber or ceramic rubber to increase grip on the belt and improve traction
  • Accessories for conveyor belt construction, roller supports, triple stations, couple stations, cantilever roller pairs, polyurethane scrapers, rubber scrapers, tungsten or Widia scrapers for belt cleaning
  • The steel rollers, the most demanded by the market, have a shell composed of a tube and bearing housing heads made integral by pressure. They are mounted on angular or radial ball bearings, pre-lubricated, and protected with double-labyrinth dust seals.

Global Nastri offers idler rollers for conveyor belts and roller conveyors, these rollers are mounted with triple labyrinth seals mounted on permanently lubricated ball bearings. Thanks to a well-stocked warehouse, we are able to provide a complete series of supports to fully meet customer needs with extremely fast turnaround times.
