GREASES FOR ROLLER BEARINGS. ADDITIONAL TESTS ON LITHIUM BASED GREASES AND TESTS ON SODIUM AND CALCIUM-BASED GREASES
Within the scope of its programme of work, and taking into account the information obtained from the series of tests dealt with in detail in Interim Report No. 1, the Committee has continued its investigations, particularly with a view to the lubrication of roller bearing axle-boxes. Tests have been made on: lithium-based greases, by means of testing machines whereby shocks representative of those produced by rail joints are transferred to the axle-boxes under test (see Appendices 7a and 19), sodium-based and calcium-based greases, by means of the various testing machines already used, with and without the application of shocks. These greases were placed at the disposal of ORE by the Administrations currently using them at the time of the tests. The results of the tests dealt with in this report show that the shock load tests make a useful additional contribution to the more reliable assessment of the ability of a grease to retain its properties effectively in service. However, running tests of rather long duration must, for their part, confirm the lubricating qualities of the grease. The comprehensive results of the tests carried out now allow the overall picture to be obtained as a guide for fixing the test methods to enable the characteristics properties of greases for roller bearing axle-boxes to be defined, even if, bearing in mind the limited number of tests and samples, formal conclusions cannot be deduced from these.
