Functions of Ball Bearings
Ball bearings, also known as anti-friction bearings, are small metallic or ceramic spheres used to reduce friction between shafts and axles in a number of applications. Ball bearings are often used in a series to absorb the weight placed on a moving part, or in individual cages to reduce friction in axle assemblies. Most ball bearings are manufactured to meet very exacting standards of roundness, since any deformation can cause the moving parts to fail unexpectedly.
Ball bearings are typically used to maintain space within the moving parts of a rotating object, such as a wheel or gear. Ball Bearings are commonly found in bicycle and car tires. The best place to shop for ball bearings is via the Internet, where a wide variety of products are offered.
Ball bearings typically support both axial and radial loads and can tolerate some misalignment of the inner and outer races. Also, balls are relatively easy compared to other kinds of rolling elements. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings.
