Patent ID: 8703675

Claim:
A high speed bearing grease composition comprising: more than 50% by volume of an oil fraction, wherein the oil fraction has a complex viscosity between 0.003 Pa s and 0.05 Pa s at 40 deg C.; more than 10% by volume of a paraffin wax, wherein the paraffin wax has a melting point in the range between 75 deg C. and 125 deg C.; and more than 5% hydrocarbon based oil stabilizer by volume, the oil stabilizer having a higher viscosity than the oil fraction, wherein the hydrocarbon based oil stabilizer comprises at least one alkanes from the group of C12 to C22, C23, C26, C27, and C28 alkanes, wherein the high speed bearing grease composition is essentially free of metallic soaps and polyurea.
