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. This group of rollers is called a zone. Choose the belt for your maximum load.  Note the “Max” loads below exceed our recommendations, but customer have been successfully running at those higher loads using boxes at least 80% as long as the zone:

    Round Belts or Flat Belts with Guard Sleeves
  8. 1/4" round belts can move up to 80 lbs per roller if zones are only three rollers long, i.e., one slave on each side of a powered roller (green end cap). If the rollers do not have grooves, then 92A flat belt can be used and move up 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.

    Flat and Round Belts Combined
  9. 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. For more info Click here.

Longer Lasting Belts:  Seven years ago 40,000 of our 3/16 HT BLUE belts were installed in two large postal distribution centers. Since then, they have been running 24 hrs/day 7 days/week, and they are still going strong even though some tubs are over weight and have soft bottoms. Over 1 million are in service in postal distribution centers throughout the world. Also see "Longer Lasting Belts".

For the best in powered roller belts, motorized roller belts, Power Moller belts, and RollerDrive belts, insist on Urethane Belt.
