Conveyor Belt Alignment: Tri-Return Training Idler

Self-adjusting 3-idler design centers conveyor belt automatically, preventing belt damage and spillage due to misalignment.

Misaligned conveyor belts can wear the edge of your belting and damage your conveyor structure. Misalignment is also a major cause of material spillage, which decreases the life of your idlers, increases overhead due to cleanup cost, and is a serious safety issue.

The Tri-Return Training Idler uses a patented concave arrangement of three idler rolls on a center pivot to keep your belt in line. The center roll is horizontal and the two outer rolls are mounted at a descending angle. This roll arrangement allows the trainer to fit the full cup of the belt.

Automatically corrects misalignment, preventing belt damage and spillage.
Patented concave roller design conforms to belt, thus contacting the entire width of the belt.
Rubber coated idler rolls reduce carryback buildup, increase the life of the rolls, and speed the Tri-Return's reaction time.
Easily replaces existing return idlers with easy installation.
Belt supported by 6 bearings, versus 2 in a single flat roll.
Works on reversing belts, unlike most other idlers.
Low maintenance, because the belt is centered automatically -- no need for constant adjustment.

Tri-Return Training Idler conforms to belt.

Patented Concave Idler Design

The Tri-Return's idler rolls are mounted on a steel frame with a central pivot point and guidlers on either side, enabling the Tri-Return to conform to the natural cup of the belt -- contacting the entire width of the belt.

Outperforms Any Other Training Idler

The Tri-Return is unique because it uses 3 idler rolls instead of the usual single roll, allowing the Tri-Return to automatically center your belt. The Tri-Return literally beats other idlers coming and going because it works on reversing belts; most other idlers don't.

And, where the Tri-Return Training Idler prevents misalignment automatically, other idlers may just complicate your alignment problem:

Manually adjusted trainers just create more work for you. The trainer isn't doing the job -- you are.
Overly complex designs, such as fulcrum and lever action-type trainers, aren't simple to install and maintain.
"Set and Forget" style trainers can cause problems in the future, because a one-time setting doesn't allow for changes in your conveyor as it ages (due to belt replacement, idler and pulley failures, and so on).
