BALL AND ROLLER BEARINGS IN MODERN ROLLING STOCK

An increasing number of specifications calls for ball or roller bearings to be fitted at all vital points for locomotives and coaches. Advantages which have been realized include: (1) up to 85% lower starting and about 10% lower running resistance. (2) Reduced charges for inspection and maintenance. (3) Fewer hot boxes, resulting in an increased availability factor. (4) More economical use of lubricants. (5) Maintenance of axle and valve gear centres as designed, by virtue of the absence of wear. In the construction of locomotives and rolling stock generally, the following gives a fair idea of the extent to which this type of bearing has been used: locomotives: axleboxes, bogie driving, truck, and bogie pivots; spring compensation beams. Rolling stock: axleboxes bogie pivots. Diesel-engine vehicles; axleboxes; gearboxes; engine bearings; generator, armature bearings; motor armature bearings.
