I-120000: This type differs from other flange bearing housings, that they are designed for the use of self-aligning ball bearings with extended inner rings of the 11200 series. The outer ring of the bearing cannot be displaced axially. To avoid parts mounted on the shaft running against the cover, the inner ring protrudes 1 mm on the cover side.
