CONSTANT OY 100 K

In the automotive industry as well as in the production of other industrial and consumer goods, sintered metal plain bearings often have to satisfy a variety of requirements. CONSTANT OY K fully synthetic oils offer a solution matching the needs of sintered metal plain bearings requiring long-term lubrication under arduous conditions.

CONSTANT OY K oils have been designed for both low and hightemperature applications. These oils are availability in any viscosity grade matching your specific requirements. The special additives allow CONSTANT OY K to be used in a wide temperature range. The oils offer added reserve capacity in the upper service temperature range.

They offer good anticorrosive effect on both iron and bronze bearings. CONSTANT OY K oils can be used for lifetime lubrication of sintered metal plain bearings.

  • CONSTANT OY K oils are intended for the lubrication of sintered metal plain bearings used in precision engineering, electrical engineering, the automotive sector and household appliances.
  • The pores of sintered metal plain bearings are filled with CONSTANT OY K by means of vacuum immersion. For a longer service life, the ready-to-use product MIKROZELLA G...OY K with the respective base oil viscosity can be applied to the outer surface of the bearing by means of conventional, fully automatic lubricating systems. We recommend conducting a test with the original lubricating system under practical operating conditions.
  • Innovative product concept with special additives
  • Improved high-temperature performance through extended thermal stability– Longer component life due to good ageing and oxidation stability
  • Versatile uses due to good corrosion protection
  • Enables energy savings due to low starting and running torques
