In industrial production, it is often the small things that make the difference. High-performance lubricating greases from Rhenus Lub help minimize friction, reduce maintenance costs, and significantly extend the lifespan of your machines.<\/p>\n
They are the largely invisible workhorses that minimize friction, protect against wear, and ensure the lifespan of critical components. However, not all lubricating greases are created equal: the demands of modern systems, extreme operating conditions, and industry-specific requirements call for highly developed solutions. Simply using just any grease can have fatal consequences \u2013 from increased wear and system failures to safety risks.<\/p>\n
A lubricating grease is a carefully composed system consisting of three components: a base oil (mineral or synthetic) that performs the main part of the lubrication, a thickener (e.g., based on metal soaps like lithium, calcium, aluminum complex soaps, inorganic thickeners like bentonite, or organic thickeners like polyurea) that binds the base oil like a sponge and holds it at the lubrication point, and additives that specifically improve properties such as pressure absorption capacity, corrosion protection, or aging stability.<\/p>\n
At Rhenus Lub, we use a wide range of thickener technologies - from proven calcium and lithium soaps to high-performance lithium complex and polyurea greases for special requirements. The consistency, specified in NLGI classes (from very soft 000 to very firm 6), is precisely matched to the application to ensure optimal pumpability and adhesion.<\/p>\n
Modern machines and systems place the highest demands on the lubricating greases used. We have developed the right solution for every challenge:<\/p>\n
At low temperatures, greases can harden, lose their pumpability, and drastically increase starting torques. At high temperatures, on the other hand, they can liquefy, leak from the lubrication point, or thermally decompose, leading to lubrication film breakdown and component failure.<\/p>\n
Rhenus Lub Solution Approach: For these extremes, we offer synthetic-based greases. Special low-temperature greases, such as those for high-speed rolling bearings, ensure lubrication down to -60 \u00b0C. For the highest temperature loads, perfluoroalkyl ether greases (PFPE) are suitable, withstanding operating temperatures of up to +300 \u00b0C. Products like rhenus LKZ 2 or rhenus LKK 15 cover a wide automotive and industrial temperature range.<\/p>\n
In many applications such as rolling and plain bearings in presses, construction machinery, or gearboxes, high pressures and shock loads occur. Unsuitable greases are displaced from the lubrication point, the lubricating film tears, leading to metal-to-metal contact, increased wear (pitting, seizing), and ultimately premature component failure.<\/p>\n
Rhenus Lub Solution Approach: Here, EP-additivated (Extreme Pressure) high-performance greases are used. Products like rhenus LZN 2, rhenus ADD 2, LKX 2, rhenus LKP 15, and rhenus CAZ 2 are characterized by excellent pressure absorption capacity and, in some cases, the addition of solid lubricants. They form a resistant lubricating film that reliably protects against wear even under the highest loads and vibrations, extending the lifespan of components.<\/p>\n
Water and aggressive media can wash out lubricating greases, destroy their structure, or cause corrosion on the lubricated components. This is particularly critical in heavy industry, mining, construction machinery, or humid process environments.<\/p>\n
Rhenus Lub Solution Approach: We rely on water-resistant thickener systems (e.g., calcium or aluminum complex soaps) and special corrosion protection additives. rhenus CAZ 2, for example, offers excellent corrosion protection even under saltwater influence and prevents tribocorrosion. rhenus ADD 2 and rhenus LCA 2 are also very water-resistant. For applications with exposure to weak acids or alkalis, rhenus BCN 2 is available.<\/p>\n
Many industries have very specific requirements for lubricating greases that go beyond mere lubricating properties. These include physiological harmlessness (food industry), OEM approvals (automotive), biodegradability (environmentally sensitive areas), or special electrical properties.<\/p>\n
The choice of the optimal lubricating grease is crucial for the performance and service life of your equipment. Important selection criteria include the specific application (rolling bearings, plain bearings, open\/closed gears, guides), the operating temperature range, mechanical load, rotational speeds (nDM value), environmental influences (water, dust, chemicals), any requirements for food compatibility or biodegradability, and necessary manufacturer approvals. Our experts will assist you in selecting the appropriate grease. Furthermore, thanks to our development expertise, we are able to cater to individual customer requirements.<\/p>\n
Das bedeutet:<\/strong> Statt auf Standardl\u00f6sungen zur\u00fcckzugreifen, k\u00f6nnen Rezepturen bei Bedarf gezielt auf Ihre technischen, regulatorischen oder prozessbezogenen Anforderungen hin angepasst werden \u2013 etwa durch die Auswahl spezieller Grund\u00f6le, Additivpakete oder Verdickertechnologien. Auch Kombinationen mehrerer Anforderungen \u2013 etwa extreme Temperaturen bei gleichzeitiger Wasser- oder Chemikalieneinwirkung \u2013 lassen sich durch ma\u00dfgeschneiderte Entwicklungen zuverl\u00e4ssig adressieren. So entstehen Schmierfette, die exakt auf den jeweiligen Einsatzfall zugeschnitten sind und maximale Betriebssicherheit gew\u00e4hrleisten.<\/p>\n
