Conveyor Rollers, Roller Drives and Drum Motors
Curved design. Interroll plastic tapered rollers increase in diameter by 0.062" each inch of many lengths. Rollers may be ordered in many roller lengths from 9.88" to 35.88" for a range of 10" to 36" between conveyor frames. The small (S) and large (D) diameters of the rollers are dependent upon the roller length.

Belt Length Calculator
Assuming that the pulleys have diameters of 6 and 20 inches, you need a belt that's exactly 153.72 inches. To find that number on your own, you need to use the belt length formula: Belt length = π/2 × (DL + DS) + 2L + (DL - DS)2/ (4L), where: DL is the diameter of the larger pulley (here 20 inches); DS is the diameter of the smaller pulley ...

Motor Sizing Basics Part 4
When pulleys, belts, gears, sprockets, chains, etc. are used as the transmission mechanism, the dynamic radial load is calculated with the following equation. W = T / y. With a belt conveyor, the motor torque provides the driving force that generates work. This is shown as T, which is the amount of torque in N·m.

Crowned Pulleys — Which Option is Right for You?
Even on troughed conveyors, flat face and crowned pulleys are generally used. On pulleys with < 24" face width, some engineers prefer a convex crown pulley shape. Others prefer a straight taper with center flat. A convex crowned pulley usually has an increase of +/- 1/16" per foot of pulley width. Therefore, an 18" face width pulley (4 ...
