Semi-locating bearings, allowing axial fixation on one side and floating (axial displacement) on the other. Corresponding to the SL1849 series. NNCF type bearings feature an inner ring with three ribs and an outer ring with one rib, enabling axial positioning in one direction. A retaining ring is installed on the opposite side of the outer ring ...
