Self-aligning ball bearings show angular mobility and insensitivity to misalignment of the shaft to the housing.
They consist of double rows with a convave raceway in the outer ring and have the smallest friction among all bearing types.
The series 112 is equipped with an extended inner ring and a location slot on one side of the inner ring and is located by means of dowel pins. The tolerance of the bearing bore for this series is J7, which makes them easy to fit..
