Plain bearings come in as many and varied forms as their applications – from crankshaft bearings and camshaft bearings to fixed bearings and sintered bearings as well as bronze plain bearings, self-lubricating plain bearings and radial bearings. To match the diversity of the types of bearings and their applications, the range of specialty lubricants from Klüber Lubrication is equally wide. This ensures they are optimally tailored to the plain bearings in each application case and their ambient conditions and tribological systems, thereby providing the best possible lubrication, long-lasting durability and long service lives.
Lubricating greases for plain bearings in the mixed friction regime
Mixed friction involving partial contact of the friction bodies, for example where there is high surface pressure in combination with low speed, as is generated during starting and stopping, pose a special challenge for the lubrication of plain bearings. Klüber Lubrication has developed lubricants for grease-lubricated metal and plastic plain bearings specially for this purpose. They contribute to the optimum formation of a lubricating film and are particularly notable for their compatibility with the bearing material. This results in low-wear operation and up to ten times longer lifetimes compared to conventional plain bearing greases.
Bonded coatings for dry-running plain bearings and for running-in optimisation
Where it is not possible to produce a hydrodynamic film of lubricant, or under extreme operating conditions, bonded coatings enable the formation of a dry lubricant film between the sliding surfaces. They are applied for lifetime lubrication and can also be used as a running-in aid to support lubrication with liquid lubricants. In case of starved lubrication conditions, they can also reduce the risk of damage to the sliding surfaces in the process.
Lubricating oils for hydrodynamic plain bearings
Klüber Lubrication offers a multitude of mineral and synthetic oils for hydrodynamic plain bearings, with exactly the right one being selected in each case depending on the sliding speed, load, temperature and operating conditions. These include universal lubricating oils as well as specialty lubricants for temperatures up to 450 degrees Celsius, lubricating oils with NSF-H1 certification and other certifications for the food and pharmaceutical industries, as well as environmentally friendly EAL bio-lubricants for the marine industry or lubricants that are rapidly biodegradable for the agricultural, forestry and water management sectors.
