Gears and transmissions are used in all industries being an essential part of many production processes, reducing or increasing speed or torque. Gears are found between the primary drives (motors or engines) and the driven equipment such as conveyors, elevators, mills and screws.
Gear lubricants are crucial when it comes to trouble-free operation of these applications. During operation, the oil often has multiple tasks to fulfill including cooling and removing friction heat but above all to lubricate the sliding rolling contacts protecting against wear and friction. In comparison with all machine elements of a transmission such as wheels, bearings, shafts and seals the lubricant is the least expensive however it is essential to select the right product to warrant a trouble-free operation and increased service life of the equipment. The purpose is selecting the right lubricant based on the various parameters which are key in gear lubrication: temperature, load and gear type.
