Self-Aligning Ball Bearings Introduction
Self-aligning ball bearings are assembled with spherical ball bearings between the inner ring with two raceways and the outer ring with spherical raceways. It has the function of self-aligning because the center of curvature of the raceway surface of the outer ring is the same as the center of the bearing. This bearing can automatically compensate for the coaxiality error due to shaft deflection and shell deformation, and are suitable for the components that supporting the seat hole and the shaft can not guarantee the strict coaxiality requirements. Self-aligning ball bearings are mainly used to withstand radial load, at the same time can also withstand a small axial load, but can not withstand pure axial load. Compared with spherical roller bearings of the same size, its load carrying capacity is low, but the limiting speed is higher. Self-aligning ball bearings have cylindrical hole and tapered hole two kinds of structure and its cage material has steel plate, synthetic resin and so on.
Self-aligning ball bearings are mainly used in precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc. They are the most widely used type of bearings in the mechanical industry.

Matters Need Attention
Rolling bearings are precision components, their use must also be appropriate caution. No matter how high-performance bearings, if used improperly, it will not get the expected performance, relevant bearing Cautions below.
1. To keep their surroundings clean bearings
Even tiny invisible dust into the bearing, will increase wear, vibration and noise of the bearing. Bearing and its surrounding attachments should be kept clean, especially dust and dirt, tools and working environment must be kept clean.
2. When using the installation should carefully
Does not allow a strong punch, does not allow direct bearing percussion hammer is not allowed to pass through the rolling pressure.
3. Using a suitable, accurate installation tool
Try using a dedicated tool, try to avoid the use of cloth and short fibers such things.
4. Prevent bearing corrosion
Direct hand pick bearings, to fully wash hands sweat and coated with high-quality mineral oil before operation,especially in the rainy season and summer mainly rust. However, under the operating conditions of a particular case, the longer the life the bearing can be obtained in traditional computing, especially under light load conditions. These particular operating condition is, when the rolling surface (and the rolling member rolling path) is effectively split, and limitations as the lubricant film surface contaminants may lead to damage. ln fact, under ideal conditions, the so-called permanent bearing life is possible.
