ASTM D1743 DETERMINING CORROSION PREVENTIVE PROPERTIES OF LUBRICATING GREASES
This test method covers the 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.

ASTM D4950 STANDARD CLASSIFICATION AND SPECIFICATION FOR AUTOMOTIVE SERVICE GREASES

Corrosion preventive properties apparatus (main procedure) CORROSION PREVENTIVE PROPERTIES APPARATUS
(MAIN PROCEDURE)

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.

Technical specifications:
– Power supply: 220V 50Hz

 

 

 

 

 

 

Corrosion preventive properties apparatus (alternate procedure)CORROSION PREVENTIVE PROPERTIES APPARATUS (ALTERNATE PROCEDURE)

Consists of a group rotating at 1.750 rpm mounted on a bedplate, a calibrated thrust device with spring for placing the bearing against the rotating support. Mechanical device for the test grease inlet onto the bearing, bearings Timken LM11949 and LM 11910
– Power supply: 220V 50Hz
