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.
Polyamide resin PA pinions, both integral in the 653.13 and 653.14 series and friction in the 653.20 and 653.21 series, are interchangeable.
Motor-driven rollers with integral PA resin pinion can reach peripheral speed v = 1 [m/s] max. The speed of motor-driven rollers with steel ACC pinion must not exceed v = 0.5 [m/s].Friction rollers, with both PA and ACC pinion, operate at speeds between v = 0.3 ÷ 0.5 [m/s] max. Normal operating temperature, TN:_5 ÷ +50 [°C].
