MA Type spherical roller bearing

Spherical roller bearings with two rows of rollers, mainly to withstand radial load, but also can withstand any direction of the axial load, has a high radial load capacity, especially suitable for heavy loads or vibration load work, but can not withstand pure axial load. This type of bearing outer ring raceway is spherical, so its centering performance is good, can compensate for coaxiality error. There are two symmetrical spherical roller, the outer ring has a common spherical raceway, the inner ring has two with the bearing axis tilted at an angle of the raceway, has good centering performance, the type of bearing load capacity, in addition to withstand radial load bearing can also withstand two-way action of the axial load, has a good impact resistance.

Spherical roller bearing design, so that it has automatic centering function, that is, the bearing itself can be adjusted, the angle between the inner and outer ring alignment error, under normal load and working conditions, the inner ring rotation, allowing the existence of the following table gives the value of misalignment. Can fully achieve this given value, depending on the design of the bearing configuration and seal type and other conditions to decide, self-aligning roller bearings are designed for high radial load or even accompanied by eccentricity, improper lubrication, impurities, very high speed or very high stress environment.
