Roller bearing steel - Import export

PVC-STEEL cylindrical and tapered rollers with one or two grooves rolled on the steel tube, driven by round belt links in series or individually connected to a transmission bar activated by the motor unit. PVC and PVC-STEEL rollers with flat or toothed polyamide resin PA or steel ACC pulley driven by tangential belt or belt links in series. The diagrams and tables on page 86 show the dimensional characteristics and minimum and maximum lengths of manufacture. The rollers for flat or toothed belts are produced in the following versions: with pinion integral to the jacket for continuous transport; with friction pulley for stockpiling transport and in the connection of machines operating at different speeds.

Due to the structural characteristics of the materials of which they are made, these rollers are used for motor-driven conveyor in combined systems of handling and stockpiling of light, medium-heavy and heavy packages in normal, dusty, corrosive, and also humid and warm environments.They are made of clamped or monobloc base rollers with steel tube, crown and simple double steel pinions, aligned on the tube or at one end of the jacket.

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.

Due to the characteristics of the materials of which they are made, these rollers are used in conveyors operating in highly corrosive environmental conditions.With a state-of-the-art manufacture, they possess the requisites of the specifications for steel rollers on page 4. Operating temperature: 10 ÷ +50 [°C].

Beader tooling can be manufactured for any machine, such as CEVOLANI, FMI, SIGKRUPP, Soudronic and more.
