New Bearing Durability Test for Automotive Axle Lubricants 2009-01-2634

Currently there is no axle test aimed specifically at bearing durability in automotive hypoid axles. Existing axle tests are primarily focused on gear distress and lubricant protection of gears. In light of the new test information showing axle bearing distress, there is a need to develop a new bearing durability test for automotive and truck axle lubricants. To fulfill this need, a new bearing durability test has been developed to better assess lubricant requirements for rolling element bearing durability. Although the final test of an axle lubricant is in a driven automobile or truck, an effective screening test based on actual light duty truck conditions can be used to accelerate lubricant development to enhance bearing performance in hypoid axles. This new test simulates actual road durability tests in the lab. A specific load cycle which retains the critical road test loading conditions reduces test time and helps speed up lubricant development.
