For determination of the corrosion preventive properties of greases using grease-lubricated tapered roller bearings stored under wet conditions. This test method is based on CRC Technique L 412 that shows correlations between laboratory results and service for grease lubricated aircraft wheel bearings

This instrument it’s used to determine the anti-corrosive properties of the grease-lubricated bearings using fat stored in wet conditions. The instrument consists of a head mounted on the rotating assembly to 1750 rpm a workpiece mounted on a controller with built-in digital timer, bearing Timken LM11949 and LM 11910 and bearing assembly that would support the blocking test bearing
