Round baler dumping a fresh bale. The most common type of baler in industrialized countries today is the round baler. It produces cylinder-shaped "round" or "rolled" bales. The design has a "thatched roof" effect that withstands weather. [3] Grass is rolled up inside the baler using rubberized belts, fixed rollers, or a combination of the two.

A rolling element rotary bearing uses a shaft in a much larger hole, and spheres or cylinders called "rollers" tightly fill the space between the shaft and hole. As the shaft turns, each roller acts as the logs in the above example. However, since the bearing is round, the rollers never fall out from under the load.
In the 1920s, Case Corporation and John Deere made combines, introducing tractor-pulled harvesters with a second engine aboard the combine to power its workings. The world economic collapse in the 1930s stopped farm equipment purchases, and for this reason, people largely retained the older method of harvesting.
In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction. Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces.
Silicon nitride bearing balls, in diameters ranging from 1 to 20mm. Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls themselves are commonly referred to as ball bearings. [1] This is an example of a synecdoche.
1903 Baler (round) A baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, straw, or silage) into compact bales that are easy to handle, transport and store. Several different types of balers are commonly used, each producing a different type of bales – rectangular or cylindrical (round), of various sizes ...
