Description

Our Mobil Polyrex EM is a semi-synthetic ISO 150 polyurea grease specially formulated for use in rolling element anti-friction bearings operating under extreme temperatures. The organic polyurea thickener contains no metal ions which act as catalysts for oxidation. This special grease was designed with special antioxidants and corrosion inhibitors to prolong the life of rolling bearings operating under severe temperature and high humidity. The widened service temperature range of -22ºF to 320ºF and high speed factor of 500,000 nDm makes this the ideal lubricating grease for electric motor bearings designed to be lubricated for life.
