FREE ROLLER CONVEYORS DIAMETER MM. 60 AND PITCH MM. 80 FOR PALLETS The free roller conveyors P80 are characterized by a rollers diameter of mm. 60 mm and pitch mm. 80 and are the ideal solution when handling pallets, containers with reduced base and standard pallets with cross feed. They consist of a robust structure coated steel profile, with fixable supports and adjustable feet. The rollers are of high quality made of galvanized steel. Rotation on shielded ball bearings with permanent lubrication. The roller conveyors are built according to the scale, size and characteristics of packages to be handled.

Box weighing system to be integrated in manual idle lines When the box is positioned on the weighing station, the operator can read and check the weight of the products inserted in the box before placing it on the pallet and thus avoid errors or returns of the goods. In this way the operator can view the result of the weighing on the weight indicator without having to lift the packages to weigh them. The weight indicator is usually installed on a vertical post clamped to the structure of the roller conveyor. In this way the indicator remains positioned vertically and it is very easy for the operator to read the weight. The standard version foresees the installation of the basic DFWL indicator. On request it is possible to install the 7-key indicator also with DFWKPXP printer. The rollers used for the roller conveyors have a diameter of 50 mm and a pitch of 75 mm

PVC rollers with jacket consisting of PVC tube and bearing mounting head rigidly coupled by pressure.They are mounted on angular ball bearings at full complement with or without spacer cage, pre-lubricated and protected with anti-dust labyrinth seals. The finishes of the rollers, the executions of the bearings and the operating temperatures are showed from pages 12 to 15.The shaft fixing shapes are shown on page 19. They are used in the production of gravity, push and motor-driven conveyors.The diagrams and tables on page 18 show the dimensional characteristics.Normal operating temperature, TN:_5 ÷ +50 [°C].

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.

Steel rollers with the jacket consisting of tube and bearing mounting head rigidly coupled by pressure.They are mounted on pre-lubricated and protected radial bearings with full complement of balls.They are used in the production of light gravity and push conveyors.Normal operating temperature, TN:_5 ÷ +80 [°C].

Rollers with PVC resin polyamide PA or steel ACC pinion driven by tangential chain or chain links in series.The diagrams and tables on pages 54 and 55 show the dimensional characteristics and the minimum and maximum lengths of manufacture. The rollers are produced in the following versions: with pinion integral to the jacket for continuous transport; with friction pinion for stockpiling transport and in the connection of machines operating at different speeds.

Rollers with frustum of thermoplastic resin sectors and with polyamide PA or steel ACC pinion driven with chain links in series. The diagrams and tables on page 78 show the dimensional characteristics and lengths of manufacture. The rollers are produced in the following versions: with pinion integral to the jacket for continuous transport; with friction pinion for stockpiling transport.

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.

Rollers PVC-STEEL rollers with resin polyamide PA or steel ACC pinion driven by tangential chain or chain with links in serie. The diagrams and tables on pages 66 and 67 show the dimensional characteristics and minimum and maximum lengths of manufacture. The rollers are produced in the following versions: with pinion integral to the jacket for continuous transport; with pinion clutch for stockpiling transport and in connection of machines operating at different speeds.

With PVC pipe and head, with steel tube and PVC head. They are mounted vertically with sliding guide functions; horizontally for special applications such as the mounting for tangential belts in motor-driven conveyors through driven base rollers or rollers with pulley for flat belt. With plastic wheels on steel axles, assembled in sequence, they are used as an alternative to tapered rollers in gravity curves for the handling of packages with a flat supporting surface and light loads. The wheels can be individually assembled, fixed on flatbeds by means of suitable brackets, in correspondence with exchanges between curves and tracks with idlers, in conjunction between tracks with ortogonal motor-driven rollers or with the function of guide-abutment of packages.
