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.
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite [1]). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed ...
Smart Parts has continuously strived to market non-screw in type tank systems for use with their markers. These types of air systems are mounted directly to the marker and don't use a standard "screw-in" type ASA adapter. The first version of this air system was the Max-Flo manifold in 1999, which continued until mid/late 2003.
Direct part marking (DPM) is a process to permanently mark parts with product information including serial numbers, part numbers, date codes, and barcodes.

Steel engraving is the same technique, on steel or steel-faced plates, and was mostly used for banknotes, illustrations for books, magazines and reproductive prints, letterheads and similar uses from about 1790 to the early 20th century, when the technique became less popular, except ...
EOBRs do not automatically record changes in non-driving duty status and, therefore, is somewhat similar to paper logs being that it is only accurate while the truck is in motion. Companies are now offering extra on board components that can accurately record the amount of rest time a driver spends in the sleeper berth and electronically ...
