The performance of any bearing depends on the properties of the chosen alloy and its heat treatment. Selecting a material with the correct hardness, corrosion resistance and fatigue life ensures that the bearing will perform reliably within the operating and environmental parameters of the application. AUB uses different materials to produce various bearing components. These materials are processed to obtain ideal characteristics to maximize bearing performance and service life. The materials described here are the most commonly used. The bearing material is heat treated in-house for optimum hardness and dimensional stability.
If the cage is found to be damaged when inspecting a failed bearing, it can be difficult to determine the cause in many cases. Often, other parts of the bearing are also damaged, making it more difficult to find the cause of the failure. However, based on more than 20 years of manufacturing experience, AUB concluded that there are certain main reasons for cage failure.

Shielded and sealed bearings can improve bearing performance and extend its service life. Bearings are used to reduce friction between the moving parts of a machine in order to achieve a desired speed – bearings reduce friction either by making no contact or simply lubricating. Also, it tends to support the support of different parts of the machine.
At first glance, ball bearings are relatively simple mechanical parts. However, analysis of their internal geometry reveals that they are very complex. For example, the conformity of the balls to the raceway, the radial clearance and the number of balls all affect the ability of a ball bearing to support loads under various conditions. 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.

Thrust bearings bear forces in the same direction as the shaft. They can be divided into two categories: thrust ball bearings and thrust roller bearings. Thrust ball bearings are used to provide high performance, while thrust roller bearings are often used in applications requiring high load carrying capacity.
Angular contact bearings are designed so that the bearing forms a contact angle between the races and the balls when in use, with inner and outer raceways slightly offset from each other, which causes the balls to be mounted at an angle. Due to this offset, they are suitable for carrying radial and axial loads. […]
