Syngear Heavy Duty Series

Syngear Heavy Duty Series

Most industries in today's world are shifting their focus toward efficiency improvements by putting an emphasis on reducing energy requirements for equipment used in plant operations and for vehicular equipment. Technological advances in lubricants have helped reduce the input power used to operate equipment by reducing friction. Summit has developed synthetic gear oils which will not only reduce frictional drag, but will also protect gears against failures associated with heavy loading.
