ASTM D3527 - Life Performance of Automotive Wheel Bearing Grease

We perform lubricating grease testing by ASTM D3527 to evaluate the high-temperature life performance of wheel bearing greases under laboratory conditions. Grease is distributed in the bearings of a modified automobile front wheel hub-spindle-bearings assembly. The assembly is heated and operated in cycles indefinitely until grease deterioration causes the motor to shut off. The grease life is expressed as the accumulated on-cycle hours of the test.
