Grooved rollers for round belts transmission
Idle rollers with grooves made directly on the steel tube are intended for round belts transmission as a very simple and economical solution.
The belts should have a section of Ø 4-5 mm or max. Ø 8 mm.
Rollers may be “GL, GM and 117” series in execution “E” (1 groove) or in execution “F” (2 grooves), with standard steel tube “N”, with electrolytic zinc-plating “J” and “Z” or PVC coating “P”.
Since the handling speed may be high, even though with restrained loads, particular care shall be taken in choosing the rollers in relation to the expected dynamic stresses.
