Outer spherical ball bearings with housings are composed of sealed outer spherical ball bearings on both sides and cast (or stamped steel plate) bearing housings. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring.

Ball thrust bearings are available which are specifically intended to take axial loads alone. The most common configuration for radial ball bearings is the single row version, which could be shielded or sealed depending on whether it is to be used within a housed area—a transmission, say—or in an exposed environment such as on a bicycle wheel.

The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges. This allows the bridge structure to expand and contract with temperature changes.

First, the ball is traveling forward at a constant velocity. You can see that by the even spacing of the tick marks along the horizontal axis in the figure below. As time unfolds, the downward velocity of the ball increases at the rate of 9.8 m/s 2, creating the uneven spacing in the vertical location of the ball (ticks on vertical axis).
