Y-bearings with a standard inner ring

Y-bearings with a standard inner ring (fig. 1) have normal tolerances for the bearing bore diameter and are locked onto the shaft using an appropriate interference fit. These bearings in the 17262 and 17263 series have the same dimensions and features as deep groove ball bearings in the 62 and 63 series, but have a sphered (convex) outside surface. The bearings are suitable for applications where the direction of the load alternates and where smooth running is a key operational parameter. They can accommodate heavier axial loads than any other Y-bearings and can operate at the same speeds as a corresponding sealed deep groove ball bearing. They do not have any lubrication holes in the outer ring as standard. Bearings with designation suffix B have two lubrication holes in the outer ring, one on each side, positioned 120° apart.
SKF Y-bearings with a standard inner ring are available for metric shafts from 17 to 60 mm.
