ASTM D1743

Purpose:

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 41 that shows correlations between laboratory results and service for grease lubricated aircraft wheel bearings. 

Operating Principle:

Distributes a lubricating grease sample in a roller bearing by running the bearing under light thrust load. Corrosion preventive capability is determined on a pass/fail basis by the presence of rust spots (1mm or larger) on the bearing race after a 60 second run-in period, followed by prolonged exposure to water at constant temperature.

Supplied complete with following accessories:

• Bearing Holder Assemblies (3) - Consisting of: 1kg weight, Upper and Lower Plastic collars for cone, Plastic collar for cup, Plastic jar with screw cap, Metal screw, 
• Run-In-Stand
• Spindle/Thrust Loading Device
• Mechanical (Bearing) Grease Packer
• Pliers to remove bearing from grease packer
• Syringe - 100 ml volume with 16 gauge needle & 100 mm in length
• Stop watch 
• Test Bearings (3) (cone and roller assemblies)

Note:

• End user also requires Humidity chamber and Hot air oven to carry out the complete test. 
• Reagents and solvents shall be arranged by the end user to clean and condition the bearings
