Picking
conveyor idlers

Belt width determines the length of each idler roll. Standard widths include 18, 24, 30, 36, 42, 48, 60, 72, and 96 inches.

Measure the angle between the center roll and wing rolls.

Measure the long center roll and the shorter wing rolls to maintain correct replacement dimensions.

Calculate the required CEMA rating (B, C, D, E, or F) based on belt width, material density, belt speed, and conveyor length. Picking idlers have lower capacity than equal troughing idlers of the same CEMA class because the center roll carries most of the load.

Standard roll diameters range from 4 to 7 inches for picking idlers, depending on CEMA class. Heavier loads and higher belt speeds require larger diameter rolls.

Note whether your existing idlers use standard top mount (conventional bracket mounting), channel inset mounting (low-profile installation for clearance-restricted applications), or web mount configurations.

Match bearing type and seal configuration to your operating environment.

Standard steel rolls suit most sorting applications. Specify rubber-cushioned rolls for impact absorption at loading zones, noise reduction in occupied work areas, or chemical resistance in harsh environments.

Standard painted frames work for general applications. Select galvanized frames for outdoor installations or stainless steel frames for corrosive environments and food-grade operations.
