Structural Features of Self-Aligning Bearings
May 25,2026
Outer raceway: Spherical in shape, with the center of curvature coinciding with the bearing center, thereby ensuring self-aligning capability.
Inner-ring structure:
Spherical roller bearings typically have either a cylindrical bore or a tapered bore (taper ratios of 1:12 or 1:30) to facilitate installation and adjustment.
Spherical roller bearings are available with either cylindrical or tapered bores; tapered-bore bearings can be fitted with withdrawal sleeves or locknuts to facilitate installation and removal.
Rolling element:
Spherical roller bearings use spherical rolling elements, providing a large contact area and high load-carrying capacity.
Spherical roller bearings utilize barrel-shaped rollers, which provide line contact with the raceways, enabling them to withstand higher loads.
Cage: Materials include stamped steel sheet, synthetic resin, and solid brass, selected based on operating conditions.
