EAGLE XVI. BEARINGS. 7C114 Attached is a report on the bearing tests. From the results so far, the tests show that as regards life of bearings :- (1) Castor oil is better than Prices 'C'. (2) Pressure feed is better than gravity feed. (3) Floating bush is better than a fixed bush. The temperature we find gives us a good indication of *** how long the bearing is likely to last. In the case of the fixed bush and also the gravity feed, the temperature of the bearing fluctuated considerably before it failed. We have received AJSL/ML.12.25 and will put in hand the alterations to the rig. We are of the opinion that this rig will prove exceedingly useful in testing out oils, bearings and bearing materials.
