1311
The 1311 is a self-aligning ball bearing with a 55mm bore diameter from the 13 series. Self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to accommodate angular misalignment between the shaft and housing.
These bearings are commonly used in applications where shaft deflection or mounting errors are present, such as agricultural equipment, conveyor systems, woodworking machinery, and general industrial equipment where alignment cannot be precisely maintained.
