Gears and transmissions play a vital role across industries, serving as essential components in numerous production processes where they adjust speed or torque. They are commonly positioned between primary drives—such as motors or engines—and driven equipment like conveyors, elevators, mills, and screws.

Gear lubricants are essential for ensuring smooth and reliable operation in these applications. These lubricants have multiple critical functions during use: they cool and dissipate frictional heat, and most importantly, they lubricate sliding and rolling contacts to guard against wear and friction. While lubricants are typically the least expensive component in a transmission system—compared to wheels, bearings, shafts, and seals—choosing the correct lubricant is key to achieving trouble-free operation and prolonging equipment service life. Selecting the right lubricant involves evaluating important parameters in gear lubrication, including temperature, load, and gear type.
