Most conveyor down-time is related to worn-out "trolley" bearings. Manufacturers recommend bearing replacement once every 5 years (minimum) so the conveyor's motor and gear reducer can operate with minimal stress and friction. Trolley Bearing Co.'s replacement nylon bearings are the same bearings used by manufacturers.
