Pvc-steel Idlers

Idle rollers of PVC and PVC-Steel idlers with double cylindrical tube, tapered idlers with frustum of polyamide resin sectors.They are used in the production of gravity or push curves.The diagrams and tables on page 34 show the dimensional characteristics.Normal operating temperature, TN:_5 ÷ +50 [°C].

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.

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].

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.
