Kluber Lubrication on specialty lubricants for sintered metal bearings

August 27, 2018 By Mike Santora

Kluber-lubrication-sintered-metal-bearingsIn electric motors or fans, sintered metal plain bearings are often preferred over rolling bearings or plastic plain bearings. Sintered bearings offer many operational benefits such as smooth running, maintenance-free operation, long service life and good overall economy.

Every passenger car contains a substantial number of electric motors, supported by two sintered metal bearings each. Sintered metal bearings are also widely used in fans, household appliances and power tools. Because of the wide range of applications it is important to ensure that the bearing lubricant fulfils the operational requirements of the component in each case. In addition to the specific bearing design requirements it is important that sintered metal bearings are impregnated with a high-quality lubricant to ensure reliable bearing function and longest service life.

Klüber Lubrication offers a wide choice of lubricants for sintered metal bearings to meet all operational requirements. Among this range are universal lubricants for a wide range of applications as well as niche products for extreme requirements. Klüber Lubrication has subjected these products to comprehensive testing under conditions typical of sintered bearing applications.

Each lubricant option, therefore, will provide particular benefits for individual application conditions, such as High-speed suitability with lowest self-generated temperature increase, combined with lowest start-up wear characteristics and high thermal stability, thus improving the lubricant’s aging resistance and prolonging bearing service life. Good low-temperature stability preventing squeaking noise, thus ensuring lowest drive power in micro motors.

Oil or fluid: that is the question

We have developed both, oils and fluids for the impregnation of sintered metal bearings. Impregnating oils are often recommended- ed for applications at constant rotational speeds. Impregnating fluids are generally the lubricant of choice when more problematic friction conditions are to be dealt with, e.g. mixed friction, as may occur in applications with very high or very low peripheral speeds or frequent changes in the direction of rotation. Fluids normally lead to a longer service life of the sintered bearing and they also enable smoother running. Experience has also shown that the noise behavior of fluids is better than that of oils.

Additional lubrication for longer bearing life

For applications with particularly taxing requirements, additional lubrication by means of MIKROZELLA may be advisable. MIKROZELLA is a plastic gel-like reservoir which can increase bearing life significantly.

Individual consulting

Klüber Lubrication can analyze your application and consult with you in lubricant selection. Considering the numerous factors influencing the operation of sintered bearings, such consult-
ing is indispensable. In cases where the right lubricant has not yet been developed, Klüber can adjust the oil type, viscosity or additive content of existing products so that they match your application.
