Conveyor idlers
Troughing idlers. Troughers are the most common idlers used on the carry side of the conveyor. Extending their life expectancy can be a challenge. Our proven seal design and low maintenance rollers lead to less downtime and increased profits. 's troughing idlers come in 20°, 35°, and 45° and meet all CEMA dimensional requirements.
IMPORTANT – SAFETY INSTRUCTIONS
It is good practice to use a 20 degree troughing idler as a transition idler for the first and last idler when using 35° troughing idlers and a 35° idler when using 45° troughing idlers. Place idlers in a position by sliding them in the direction of belt travel until the footpads sit against the mounting bolts. Tighten bolts by hand.

Understanding the Importance of Troughing Idlers
Troughing Idler Benefits. Troughing idlers have two significant advantages. Because the troughing idlers maintain the belt's form throughout its travel, it is more secure at carrying capacity. Secondly, troughing idlers minimize the quantity of material that may accidentally spill on the conveyor system. With minimal downtime from cleaning ...

Understanding the Role of Troughing Idlers
A troughing idler is comprised of a central idler roll, which has a fixed width, and two or more wing idlers located on each side of the central idler roll. The wing idlers can be adjusted up or down to change the toughing angle, which affects the depth of the trough created by the conveyor belt as it moves. Benefits of Troughing Idlers
