Automotive Wheel Bearing Grease Leakage Tendencies Tester Under Accelerated Conditions       

Product model: JF25962

Product Introduction

This instrument is measuring a laboratory procedure for evaluating leakage tendencies of wheel bearing greases when tested under prescribed conditions.

Testing Principles: The test grease is distributed in a modified, automobile front wheel hub-spindle-bearings assembly. While the bearings are thrust-loaded to approximately 111N, the hub is rotated at 1000 rpm and the spindle temperature maintained at 160.0 °C ± 1.5 °C for 20 h. Leakage of grease or oil, or both, is measured, and the condition of the bearing surface is noted at the end of the test.
