Do you know characteristics of double row spherical roller bearing?

Double row spherical roller bearing are bearings with drum shaped rollers assembled between the inner ring with two raceway and the outer ring with spherical raceway.
The characteristics of double row spherical roller bearing

For detachable double row spherical roller bearing, the inner and outer rings can be installed separately, which simplifies the installation process, especially when interference fit is required for both inner and outer rings.When loading the shaft with the inner ring in place into the bearing box with the outer ring, care must be taken to check whether the inner and outer rings are correctly aligned to avoid scratching the bearing raceway and rolling parts.Mounting sleeve is recommended for cylindrical and needle roller bearings with inner rings without flanged flanges or with flanged edges on one side.

Double row spherical roller bearing can be easily folded on the shaft by using fasteners or by backing out.Part of double row spherical roller bearing outer ring raceway is spherical, with internal bearing performance, to adapt to the shaft and the relative deviation of hole, can bear radial load and impact load, also can absorb a certain amount of bidirectional axial load, the bearing can limit the shaft or the shell axial displacement within the scope of the axial clearance of bearing, the double row spherical roller bearing principle and structure characteristics and self-aligning ball bearing is the same, in the case of load capacity and limit speed permission, can substitute each other.
Double row spherical roller bearing are double row raceways on the inner ring, spherical raceways on the outer ring and drum shaped bearings on the rollers.The raceway surface center of the outer ring is consistent with the bearing center and has automatic centering performance. It can be used normally even when the inner and outer ring is inclined due to installation error between the shaft and the bearing box or deflection of the shaft.
