List of railroad truck parts
Also called an axle box, or journal box in North America, an axlebox is the truck or bogie assembly that houses the end of the axle. Early axleboxes contained plain bearings in which the axle spun in a bed of oil. Plain bearings are now illegal in interchange service in the United States, Canada and Mexico; in these countries modified journal boxes now enclose roller bearings. As early as 1908 axle boxes contained a set of long cylindrical rollers allowing the axle to rotate. It was also used on steam locomotives such as the Victorian Railways A2 class, the LMS Garratt, the LSWR 415 class, and the GCR Class 1.[dubious ]
Truck side frameEdit
Each truck has a bolster—a transverse floating beam—between the side frames. It is the central part of every truck on which the underframe of the railcar or railroad car is pivoted through the center pivot pin.
There is one side bearing located on each sde of the centerplate on the truck bolster.
