All grease-lubricated gears need to be protected against wear and corrosion – which is where specialty lubricants can help: Whether plastic or metal gears, bearings and hammer mechanisms in hand-held power tools or spur gears, spur bevel gear units, worm gears, planetary gears or spindle bearings in high-speed machine tools. The special requirements for gear lubricants differ depending on the application and environmental conditions. In a best-case scenario, they are already taken into account during the development of an application. This often simplifies design when, for example, the formation of a grease collar has a sealing effect against environmental influences, or the highly adhesive specialty lubricants for gears reduce gear wheel splashing losses and leakage. Solid or consistent lubricating grease is always immediately available at the lubrication point and therefore permits flexible gear orientation. Also in start-stop operation and at low speeds, greases with their higher lubricant film thickness show their strengths compared to oils and other lubricants. Due to their viscosity-temperature behaviour, lubricating greases can also be used in a wide service temperature range – even at very high and very low temperatures. With their water resistance, they increase operational reliability in wet environments. For applications in the food industry, they are also available as specially registered NSF H1 lubricants for grease-lubricated gears, therefore meeting strict compliance requirements.
Klüber Lubrication develops specialty lubricants in close cooperation with the industry to increase efficiency and extend the service life of components in numerous applications.
