Round transmission belt for motorized roller conveyor
Dura-Belt
Powered roller belts are also called motorized roller belts, RollerDrive belts, Power Moller belts, and Microroller belts. They connect a motorized roller to a group of six to ten slave rollers, called a zone. Usually the motorized roller is in the center of the zone, but on inclines it is at the top end.
Abuse Resistant, HT Rough Green Belts
Jammed boxes will bring slave rollers and belts to a halt. As soon as a sensor detects a jam, the PLC must turn off its powered roller quickly -- within 4 seconds. Otherwise, the powered roller will continue to turn under the jammed box, forcing the belts to slip and overheat. Such abuse will cause premature belt failure.
Smooth belts have a high coefficient of friction (COF), so when forced to slip, they heat up and abrade or melt. Rough green belts have a low COF that lets them slip easier with less heat build up, so they can take more abuse. The trade off is that they slip too soon, so they cannot move heavy boxes like smooth belts. We recommend rough green belts in applications where boxes are light to moderate weight, and where PLC's are set to power through jams -- or where there are no sensors to detect jams.
Round Belts or Flat Belts with Guard Sleeves
/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.
