Like all other physical components of the hydraulic chamber and gearbox, Hydraulic & Gear Oil plays a very important role in keeping the projected life of a gearbox, its seals, and the desired performance of the gearbox within an application. These oils are made as per the specific value of a machine and its components. Some of these factors are the value hardness of the gears, bearing selection, materials used in manufacturing, and so on. Whether gearboxes are designed for food manufacturing or for industrial machines, the Hydraulic & Gear Oils selected must be chosen for optimum performance under a specific set of operating conditions.
