Powered Roller Belts
Powered roller belts are also called motorized roller
belts, RollerDrive belts and Power Moller belts. They connect multiple
(usually 9) slave rollers to a motorized roller that is located in
the middle of a group of ten rollers. For maximum drive five slaves
are on one side of the motor and four slaves are on the other side.

Belts or Flat Belts with Guard Sleeves
1/4" round belts can move up to 80 lbs per
roller if zones are only three rollers long, i.e., one slave
side of a powered roller (green end cap). If the rollers do
not have grooves, then 92A flat belt can be used and move
to 120 lbs per roller. Flat belts may need Guard Sleeves
(blue) to prevent pallets from dislodging the belts. The red
Tracking Sleeves prevent the flat belts from walking.
and Round Belts Combined
- A combination of flat and round belts can move very heavy loads
by creating "pseudo powered rollers". Adjacent is a powered roller
zone with 14 rollers that can theoretically move heavy loads up
to 80 lbs per roller -- or 180 lbs per roller if another set of
flat belts is added to the other end of the rollers. If you specify
grooves that are more than 1.25" apart, you can use wider flat
belts that could theoretically move loads up to 400 lbs per roller.
