1213K Self-Aligning Ball Bearing, Double Row

Self-aligning ball bearings are double row radial bearings with a common sphered raceway in the outer ring. This design allows the bearing to compensate for angular misalignment between the shaft and housing, making them ideal for applications where precise shaft alignment is difficult to maintain.

Typical applications include agricultural equipment, conveyor systems, woodworking machinery, and general industrial equipment where shaft deflection or mounting errors are expected. The tapered bore design facilitates mounting directly onto tapered shafts or adapters with locking devices.
