The self-aligning roller bearing has two rows of rollers, which mainly bear radial load and axial load in any direction. With high radial load capacity, it is especially suitable for working under heavy load or vibration load, but cannot bear pure axial load. The raceway of the outer ring of this kind of bearing is spherical, so its centering performance is good and it can compensate the coaxiality error.
There are two rows of symmetric spherical rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways inclined at an angle with the bearing axis, with good centering performance. When the shaft is bent or installed eccentrically, the bearing can still be used normally. The centering performance varies with the bearing size series. Generally, the allowable centering angle is 1~2.5 degrees. This type of bearing has a large load capacity. In addition to bearing radial load, the bearing can also bear the axial load of two-way action, with good impact resistance. Generally, the allowable working speed of the self-aligning roller bearing is low.
The self-aligning roller bearing can be divided into symmetric spherical roller and asymmetric spherical roller according to the sectional shape of the roller. The asymmetric self-aligning roller bearing is an early product and mainly serves for the maintenance of the main engine. When the main engine is newly designed, the symmetric self-aligning roller bearing is rarely used. The internal structure is comprehensively improved, designed and optimized. Compared with the self-aligning roller bearing produced in the early stage, it can bear greater axial load. The operating temperature of this bearing is lower, so it can adapt to the requirements of higher rotational speed. According to whether the inner ring has a baffle and the difference of the cage used, it can be divided into C type and CA type. The C type bearing is characterized by no baffle and the steel plate stamping is used to maintain the inner ring. The CA type Terrain bearing features retaining edges on both sides of the inner ring and a machined solid retainer.
The self-aligning roller bearing is divided into cylindrical bore and conical bore. Installed on the matched tightening sleeve, it becomes the rear-mounted type K+H and K30+H bearings.
