Double Row Spherical Roller Bearings

Double-row spherical roller bearings are bearings with double-row raceways in the inner ring, spherical raceways in the outer ring, and drum-shaped rollers. The center of the raceway surface of the outer ring is consistent with the center of the bearing, and has self-aligning performance. It can be used normally even if the inner and outer rings are tilted due to installation errors between the shaft and the bearing box or shaft deflection.
Double-row spherical roller bearings can be easily assembled and folded on the shaft by using fasteners or retraction. The outer ring raceway is part of the spherical surface. The bearing has internal alignment performance to adapt to the relative deflection of the shaft and the seat hole. It can withstand radial heavy loads and impact loads, and can also withstand a certain two-way axial load. The bearing can limit The axial displacement of the shaft or housing is within the axial clearance range of the bearing. The structural principle and characteristics of this bearing are the same as those of the self-aligning ball bearing. They can be substituted for each other if the load capacity and limit speed permit.
The bearing has a large radial load capacity and can also withstand heavy loads and impact loads. And because of its self-aligning performance, it can withstand axial loads in both directions to a certain extent.
Therefore, this bearing can be applied to large-scale mechanical equipment where shaft deflection may occur or assembly errors are unavoidable, such as paper-making machinery, vibrating screens, and general industrial machinery.
