LATERAL BRACKETS TO BE WELDED Straight brackets made of cold-formed sheet steel, fitted with housing for supporting the roller shaft. ADJUSTABLE LATERAL BRACKETS TO BE WELDED Cold-formed steel sheet brackets, comprising a straight bracket fitted with housing for supporting the roller shaft and a plate, connected to it by means of screw and threaded nut, for fastening to the structure by welding.The slots of the junction housings enable precise adjustment of the roller assembly.The choice and dimensions of the brackets to be adopted depend on the diameter of the roller to be supported, the series to which it belongs and the type of installation to be achieved.

Straight brackets made of cold-formed sheet steel, fitted with housing for supporting the roller axle.The choice of brackets to be welded or secured by screws depends on the type of roller to be supported and the installation to be achieved.See diagrams and tables.

They consist of two steel clamped or monobloc rollers mounted on a single “V”-folded shaft. They have the upper bearing mounting heads with hermetic closure and the lower ones, with protruding shaft, with labyrinth dust protection. The shaft is locked in the housing of the central bracket.The latter, with a base plate fitted with mounting holes, is made of cold-formed steel sheet.They are used in concave belt conveyors that operate, even in bad environmental conditions, at medium-high speed, with medium loads and sizes.

Steel rollers with the jacket consisting of tube and bearing mounting head rigidly coupled by welding.Monobloc steel rollers are used in conveyors with medium, heavy or very heavy loads. Depending on their application, the rollers have specific shapes for connection to the structure. This need is particularly noticeable in the production of gravity and motor-driven conveyors.For the correct installation of steel idlers, refer to the “Fixing rollers to structures” section on page 11.For the correct installation of motor-driven rollers, refer to the “Fixing rollers to structures” section on page 68. The diagrams and Table 60 show the shapes of the ends of the axles envisaged in TECNORULLI production’s “Monobloc steel rollers” programme.On request, other forms of connections and rollers with hubs can be considered.
