The two rollers that comprise the sets are assembled onto a single shaft of 15 mm diameter, and their external end caps hermetically sealed. Together with the central support the unitary assembly is extremely strong. Cantilevered sets are available with rollers from series RTL and MPS and their use is applicable to light or medium load capacity belt conveyor with small material piece size. The support positions the two rollers in a manner that minimizes the gap between them, without affecting their free rotation.
In this manner, the belt is perfectly supported and no damage results even to a flexible belt due to the proximity of the two support rollers. The support brackets of the sets have been designed with longitudinal “fixing” slots to allow for perfect belt alignments.
