3. Spherical roller bearings:

Depending on the internal structure, this type of bearing is equipped with a spherical roller between the outer race of the spherical raceway and the inner race of the double raceway. Divided into R RH RHA and SR four types because the arc center of the outer ring raceway is consistent with the bearing center, and has a self-aligning performance, because the shaft misalignment caused by the deflection or misalignment of the shaft or the casing can be automatically adjusted. Radial load and bidirectional axial load are acceptable.

In particular, it has a large radial load capacity and is suitable for withstanding heavy loads and shock loads. Tapered hole bearings can be assembled and disassembled on the shaft by using fasteners or withdrawal sleeves. Spherical roller

Bearings can withstand large radial loads while also withstanding a certain axial load. The outer ring raceway of this type of bearing is spherical, so it has a self-aligning performance. When the shaft is bent or tilted so that the center line of the inner ring and the center line of the outer ring are inclined no more than 1 ° to 2.5 °, the bearing can still work.
