One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.
Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low-thrust applications where there is little axial load. Cylindrical roller thrust bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to ...

Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. Common ball bearing designs include angular contact, axial, deep-groove, and preloaded pairs.
The rush into production included some unusual quirks, such as the horn ring bearing the 'Ford Falcon' logo covered by a trim ring with a 'Ford Mustang' logo. These characteristics made enough difference to warrant designation of the 121,538 early versions as "1964½" Mustangs, a distinction that has endured with purists.
A typical ball joint with cutaway view (right) An inner tie rod end cut open to expose the ball joint. In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod ...
However the bearing movement also becomes reciprocating rather than continuously rotating, which is a more difficult problem for lubrication. Notable engines to use fork-and-blade rods include the Rolls-Royce Merlin V12 aircraft engine, EMD two-stroke Diesel engines, and various Harley Davidson V-twin motorcycle engines.
