Drive Friction Factors

Belt conveyors utilize a friction drive and accordingly, when power is applied to the drive system, one run of the belt will experience a higher tension than the other. The amount of slack side tension required to prevent slippage at the drive is a function of several constant factors amongst others is the coefficient of friction between the drive system. Below is a list of standard drive pulley friction factors from various design catalogues and standards.
