An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
In wheels where friction is critical, a capstone is added on the end to prevent the shoulder of the shaft from bearing against the face of the jewel. A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter.
As of late 2013, most rail freight to New York City moves over lines on the west side of the Hudson and is unloaded in New Jersey, where it is brought by truck to the city. Railroad freight cars that enter the city or Long Island do so via the Bronx, Brooklyn, or Staten Island. [17] New York and Atlantic Railway system map
In 1924, the Muzzy-Lyon Company and Federal Bearings and Bushing, an engine bearings and bushings manufacturing company founded in 1915 by a group of Detroit businessmen, [6] merged to become the Federal-Mogul Corporation. [7] The combined company also manufactured bronze bearings, a product the Muzzy-Lyon Company had not supplied previously.
Fluid bearings generally have very low friction—far better than mechanical bearings. One source of friction in a fluid bearing is the viscosity of the fluid leading to dynamic friction that increases with speed, but static friction is typically negligible. Hydrostatic gas bearings are among the lowest friction bearings even at very high speeds.
Journal (friction, radial or rotary) bearing: This is the most common type of plain bearing; it is simply a shaft rotating in a hole. [3] In locomotive and railroad car applications a journal bearing specifically referred to the plain bearing once used at the ends of the axles of railroad wheel sets, enclosed by axleboxes (also called journal ...
