The relationship between scar diameter and load applied to the ball bearings is studied. The test used to determine the load carrying properties of a lubricant at high test load. In the case of WP or EP lubricants the ability to resist scuffing is the primary concern. The Four-Ball Tester is a good laboratory tool for developing oil with good engine wear control. The point contact interface is obtained by rotating a steel ball under load against three stationary steel balls that secured and placed in triangular pattern within a bath of lubricant.
In the last issue , we described how tribological properties of a lubricant can be measured using the SRV. The purpose of this testing is to determine the load carrying capabilities of a lubricating grease under high load applications like bearings. The 4 Ball EP test machine operates in a sliding or rolling motion.
