Monoblocs - Import export

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by welding. They are mounted on pre-lubricated angular or radial ball bearings and protected with double labyrinth, triple labyrinth dust seals with additional watertight protection. Monobloc steel rollers are used in belt conveyors with medium, heavy or very heavy loads. The diagrams and tables on page 42 show the dimensional characteristics and maximum loads.Operating temperature:-10 ÷ +90 [°C].

Clamped or monobloc steel rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded axle protrudes from one end of the tube only. They are vertically mounted, with a guiding and sliding function, in gravity or motor-driven conveyors.The technical characteristics of Series 6 rollers are those of the relative base rollers.

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.
