Introduction
features self aligning roller bearing is a double row non separable bearing & ndash; including the solid outer ring with spherical raceway, the solid inner ring and the drum roller with cage. The inner ring has a cylindrical or conical hole. the symmetrical drum roller can be freely adjusted in the outer spherical raceway. Therefore, it is possible to compensate for shaft bending and misalignment of mating surfaces, see compensation for angular misalignment. most sizes of self-aligning roller bearings are designed by X-life . These bearings have better kinematic properties and optimized raceway surfaces, and are made of high-performance materials without middle ribs. Therefore, under the same working conditions, the basic dynamic load rating and basic life rating of the bearing are significantly improved. In some applications, this means that smaller bearing arrangements can be chosen. and indicate in the dimension table. self aligning roller bearing can bear bidirectional axial force and high radial force. they are designed for high bearing capacity because they have as many and long drum rollers as possible, and self-aligning roller bearings are also suitable for extremely heavy loads. optimized tightness between roller and raceway ensures uniform stress distribution in the bearing. self aligning roller bearing can compensate angle misalignment. The allowable load corresponding to the centering angle is P & lt; 0.1 & middot; C R . See the table below. these tuning angles are allowed if: angle misalignment is constant (static angle misalignment) the inner ring is a rotating part. if the outer circle rotates, the inner circle swings, or the center adjustment angle is greater than the value in the table, the allowable center adjustment angle of the bearing will be smaller. please contact us if the above situation occurs.
