ROLLERS
STRAIGHT ROLLERS
There are two types of rollers used in straight
sections: single grooved and double grooved.
Single grooved rollers are used when connecting the
line-shaft pulleys (spools) directly to the rollers.
Double grooved rollers are used with a roller-to-roller
"transfer belt" to power the next single grooved
rollers. This is done in areas over drives and jump
chains where it is not possible to have a drive spool
on the line-shaft.
Place a single grooved roller over the obstruction
with the groove opposite the line-shaft and place the
double grooved roller next to it.
Rollers are installed at the factory for bed widths
through 24" wide. Rollers are shipped loose for bed
widths greater than 24".
TAPERED ROLLERS
Tapered rollers are used in all curves and are
grooved to provide roller-to-roller drive over
universal joints. Curve rollers for XR40 have two
grooves. Curve rollers for XR48 have three grooves
to allow all rollers to be connected together for drive
sharing.
All rollers are installed in curves at the factory for all
widths.
ROLLER INSTALLATION
• Twist all belts in the same direction. The twist of
the belt determines the direction of the roller
rotation and conveyor travel.
• When devices such as urethane belt transfers
(UBTs) are driven from the line-shaft, the motor
must run in the direction to suit the device. Do
not install rollers until after the motor is wired.
Test the belt twist for correctness before
installing all rollers in that drive unit.
• Since rollers are preinstalled at the factory in
conveyors 24" wide or less, there is a 50%
chance the belt twist will need to be changed at
installation in units containing line-shaft driven
devices like UBTs.
To install the rollers, proceed as follows:
1. Lay the rollers on the conveyor frames with
the grooved end over the line-shaft.
2. After placing the belt over the roller, put the
axle (on the line-shaft end) into the hex hole
in the conveyor side channel.
3. Since rollers have spring loaded axles,
depress the roller axle in the end opposite
the line-shaft, align the shaft with the hole in
the frame and release the axle. The spring
in the roller will push the axle into the axle
hole in the frame.
WARNING
Use a blunt object to push on the roller axle.
Pointed tools can slip and cause personal
injury.
