Top 10 Most Common Conveyor Problems. Belt Tracking Problems. Belt tracking problems occur when the conveyor belt starts to veer off-center, causing it to rub against other components and eventually wear down. This can be caused by a misaligned belt, incorrect tension, or worn components. Belt Tension Issues
Belt Conveyors | McMaster-Carr
A tensioner extends or retracts the conveyor pulley to adjust the tension on the conveyor belt. Enclosed Conveyor Belt Tensioners. ... Slide these coating strips into metal retainers that you attach to your pulley— they add friction that helps conveyor belts stay on pulleys and are replaceable when they're worn.
Roller Conveyor Design Principles: Applications And …
In gravity roller conveyors, items move due to the force of gravity acting upon them, which necessitates a slight decline along the conveyor's path. For powered roller conveyors, either individual rollers are motorized or a motor drives the conveyor belt that moves the rollers, thus propelling objects along the conveyor's length.
