Self-Aligning Ball Bearings
Self-aligning ball bearings are designed with two rows of balls and a common spherical raceway in the outer ring. This allows the bearing to automatically adjust and compensate for misalignment or shaft deflection, maintaining smooth operation even when the shaft is not perfectly aligned with the housing. They are commonly used in applications where shaft bending or mounting errors may occur.

Key Features:

Two rows of balls with a common spherical outer raceway
Automatically compensates for shaft misalignment and deflection
Handles radial loads and limited axial loads in both directions
Low friction and suitable for moderate-speed applications
Available with cylindrical or tapered bores for easy mounting
Requires less maintenance due to self-aligning capability
Commonly used in agricultural machinery, conveyors, and textile equipment
