* Please consult the Van der Graaf technical department for use of these speeds. - Other belt speeds and face widths are available. - The total weight of the unit increases by 6.72 pounds per inch above 25.59 inches. - When the drive is supplied with lagging, the covered face width is reduced by 1.42 inches. - Belt speed is measured on the center of the unit without lagging. - Listed belt speeds are under full load conditions and may be higher under no load conditions. - When an electromagnetic brake is required, the minimun face width is increased by 5.91 inches. NOTE: TM400 type drum motors are available in all standard voltages and are electrically reversible.
