MOTORS AND DRIVES

Commercial

Baldor
Baldor Electric Company’s Dodge HT500 synchronous drive system delivers high torque, low maintenance and potential energy savings with less overhung load than V-belts, sources report, adding that the HT500 belts offer longer life in wet, oily environments than V-belts in similar conditions. The companion to HT500 sprockets is the Baldor-Dodge HT500 high torque synchronous belt (8MM and 14MM metric pitch). The HT500 belt is made with polyurethane for harsh environment resistance and carbon fiber cords, for higher torque carrying capacity than commonly known aramid fiber tensile cords made belts.
