Hi Roller - Model 18-54 - Enclosed Belt Conveyors
Available in belt widths from 46 to 152 cm (1'6' to 5'), this is our original and most popular model. The unique bell-shaped carrying idler provides the trough for the belt and utilizes two external bearings as opposed to the six internal bearings associated with a conventional idler. The bell-shaped idler also has built-in self-aligning characteristics for both single and bi-directional conveyors.

The Hi Roller Conveyor incorporates a unique spool shaped idler to provide a troughed support for the conveyor belt. The spool shaped idler utilizes two external bearings as opposed to six internal bearings on more conventional idlers.
The idler is constructed with a heavy wall pipe that passes through the center of the idler. This provides rigid support. The center pipe is then reamed to just the right tolerance to accept the turned and polished stub shaft that passes through the external bearings.
This design is superior to a single continuous shaft for obvious reasons. First, installation clearances do not always permit the removal of a single continuous shaft. Second, more generous tolerances are needed to pass a continuous shaft through the complete idler. This permits shaft deflection through the idler and bearing. Third, over a period of time a continuous shaft is more apt to become seized to the internal idler which would require cutting the shaft for idler removal.
The stub shaft and bearing are supplied by Hi Roller as an assembly to assure that the shaft cannot rotate independently of the bearing and that the shaft cannot move in or out within the bearing. The bearing itself is easily adjustable for belt tracking.
