Conveyor Idler

Conveyor Idler |Pulley|Conveyor systems

Conveyor idlers play a vital role in supporting and guiding the conveyor belt, ensuring stable and efficient material handling. Among the most widely used are troughing idlers, which hold the carrying side of the belt at angles of 20°, 35°, or 45° to keep bulk materials centered and reduce spillage. On the return side, flat and V-return idlers stabilize the empty belt, minimizing sagging and extending belt service life.

For areas with heavy impact and sticky materials, specialized designs provide added protection and cleaning. Impact idlers, fitted with rubber rings or discs, absorb shock at loading points to safeguard both the belt and structure. Meanwhile, rubber disc and self-cleaning idlers continuously knock off residues and prevent material build-up, keeping conveyors running smoothly and reducing downtime.

Together, these idler solutions form a complete system that supports the belt under all conditions—from heavy-duty loading zones to return runs. Combined with our advanced sealing technology, premium bearings, and corrosion-resistant materials, our rollers deliver longer service life, lower maintenance, and reliable performance even in the harshest industrial environments.
