The rolling and sliding actions which occur in all types of gearing, such as spur, helical, worm, spiral bevel or hypoid, present a different type of challenge to lubricants compared to ball or roller bearings. Many designers, especially worm gear designers, are interested in increasing gear box efficiency. Modern designs require the most in power transfer with minimal noise and heat generation. In some cases, oils are being replaced by specially designed greases to reduce component cost by eliminating the need for seals and the machining costs associated with oil seal designs. Other gear train designs may have special operating environments including high and low temperature, corrosion and oxidation concerns.

With modern lubricants, these challenges can be met very effectively. Utilizing various semi-synthetic base oils these lubricants not only minimize friction but can inhibit wear and corrosion, dampen noise and control free motion. They can meet broad temperature requirements without oxidizing or evaporating. And they can provide manufacturers of today’s power transmission devices with an “edge” that will increase the performance and life of their products.
