Weight of bearing (approximate) 215 lbs. Auxiliary locomotives equipped with this type of journalbearing have been in service for more than three years, theearliest applications being on the Delaware & Hudson, andthe Kansas City Southern. During this period, the out-standing characteristics of the bearing has been its relia-bility tin i >ugh which it has contributed in no small measureto the success of the unit as a whole. There have beenno train detentions due either to hot boxes or other n r v_ y. JT^ Side Elevation and Cross Section of S K F Roller Bearing As Applied to Tender Booster of the Bethlehem Steel Company blasted and the non-machined interior surfaces are coatedwith heavy shellac or an aluminum paint. As is customary with locomotive driving boxes thefaces are grooved for lubricating purposes, but it is worthpointing out that the flanges are machined straight, andare not tapered in toward the horizontal center line in theusual manner. This is unnecessary, since the self-aligning property of the bearing affords completeflexibility to the axle. As pointed out above the box isstabilized by the application of the load through doubleequalizers rigidly connected together. At the presenttime, shoes and wedges are used on the pedestals, but itis believed that experience will show that these are notnecessary. The thrust on the axle is taken through the outboardrow of rollers, aga
