Sintered bearings are used whenever particularly low noise levels are required, loads are variable or little space is available. They consist of pressed metal powder whose pores are impregnated with a lubricant. The impregnating oil or fluid ensures permanent lubrication of the bearings. The choice of lubricant depends on the application and has a decisive impact on the function and service life of your bearings. High temperatures, for example, can easily increase corrosion if the lubricant is not compatible with the bearing material. Selection of the right lubricant for your application will also involve the viscosity, compatibility with plastics and seals, reduced start-up wear and thermal behaviour.
Our close relationships with automotive suppliers, equipment and sintered bearing manufacturers have provided us with extensive experience. Our wide range of speciality lubricants is continuously developing with new impregnating oils and fluids, e.g. high-performance oils covering a temperature range from -65 °C to +230 °C, and special fluids which reduce bearing noise even with frequent changes in direction.
