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.
Resin polyamide PA pulleys, both integral and friction, are interchangeable. Normal operating temperature, TN:_5 ÷ +50 [°C].
