Typically, […]
Miniature ball bearings are available in different types and in different designs to meet the requirements of almost any precision instrument application. Some bearing types include high speed radial bearings, full complement ball bearings, radial cages, angular contact bearings, thrust bearings. Subminiature and miniature bearings are usually sealed with rubber seals and boots to prevent any possible lubricant leakage or ingress of dirt.
Spherical roller bearings are very strong because the load is more evenly distributed on the rollers. Self-aligning roller bearings, often called anti-friction bearings, have a low coefficient of friction; the rollers are placed relatively loosely between the outer and inner rings, resulting in less friction and less heat; as a result, the life of the bearing The period will be extended.
Cylindrical roller bearings have high radial load capacity and moderate thrust loads. They contain cylindrical rollers, but are not true cylinders. Instead, these rollers are crowned or end relieved to reduce stress concentrations. This geometry results in low friction and allows high speed applications.
In addition to developing a wide range of super precision ball bearings, AUB prides itself on providing the best OEM solutions and advice on machine tool spindle bearings.
