Four-Ball Wear Tester

The four-ball wear tester measures the wear scar diameter and friction coefficient by rotating four steel balls in a lubricant under friction. It is used to evaluate the anti-wear and extreme pressure properties of lubricating oils and greases. It is applied in oil product development, quality control, and tribological material research.
Selection
When selecting, consider the test standard requirements to determine the load range and rotational speed parameters. Choose the lubricant testing mode based on the sample type, and review the equipment's accuracy and repeatability data. Pay attention to temperature control functions and data recording methods to ensure compliance with daily testing needs.
