The bearing was composed of two sets of cylindrical rollers, one set larger in diameter than the other, that fit on flats machined on the tapered axle-skein. In 1898, Henry Timken was awarded a patent [2] for the tapered roller bearing which used conical rollers. At the time, Timken was a carriage-maker in St. Louis and held three patents for ...
In 2003 Torrington was purchased by the Timken Company, nearly doubling its size. [4] Timken ceased all operations in Torrington and shut down the plants in 2006. [5] Timken also redistributed employees to their other plants. [2] The rest of the heavy bearing plants and needle bearing plants were eventually sold to JTEKT in 2009.
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.
GGB (formerly Glacier Garlock Bearings, then GGB Bearing Technology) manufactures self-lubricating, prelubricated plain bearings and tribological polymer coating for various industries and applications. It has production facilities in the U.S., Germany, France, Slovakia, Brazil and China.
The contact area is flooded with the lubricant or grease being tested. The Timken OK Load is the highest standard load at which the spinning bearing race produces no scouring mark on the test block, but only a uniform wear scar. [1] Timken OK Loads are listed on grease and oil property charts and are part of many specifications.
The first locomotive to use roller bearings made by Timken was Timken 1111, a 4-8-4 built by Alco in 1930. The locomotive was used on 15 American railroads for demonstration runs, and was purchased by the Northern Pacific Railroad, the last railroad to try the specially-built locomotive, in 1933.
Boston-born Willard Rockwell (1888–1978) made his fortune with the invention and successful launch of a new bearing system for truck axles in 1919. He merged his Oshkosh, Wisconsin-based operation with the Timken-Detroit Axle Company (current Meritor Inc. [1]) in 1928, [2] rising to become chairman of its board in 1940.
