The internal design of the bearing is not standardised by ISO, so it varies between different manufacturers and different series. Some of the design parameters are: Roller shape and dimensions; Flange design; Non-rotational notches in house washer; The spherical roller thrust bearings have the highest load rating density of all thrust bearings.

Spherical roller bearing with a brass cage in a cut-through view. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
On a screw, the bearing area loosely refers to the underside of the head. [1] Strictly speaking, the bearing area refers to the area of the screw head that directly bears on the part being fastened. [2] For a cylindrical bearing, it is the projected area perpendicular to the applied force. [3]
Timken 1111, also named the Timken Four Aces, was a 4-8-4 steam locomotive built in 1930 by American Locomotive Company (ALCO) as a demonstration unit for new roller bearings produced by the Timken Roller Bearing Company. It was the first locomotive built with all sealed roller bearings rather than plain bearings or a
Timken acquired its competitor, The Torrington Company, in 2003 for $840 million, doubling the size of the company and creating the world's third-largest bearing manufacturer at that time. [ 15 ] The company changed its corporate structure in 2014; the roller bearing-producing part of the company was separated from the steel-producing part of ...
The lower half of the main bearings are typically held in place by 'bearing caps' which are secured to the engine block using bolts. The basic arrangement is for each bearing cap to have two bolts, but some engines may have four or six bolts per bearing cap (often referred to as "four-bolt mains" or "six-bolt mains" engines).
