Y-bearing units
Standard SKF ball bearing units are referred to as Y-bearing units. These units comprise
a Y-bearing (insert bearing) which is a single row deep groove ball bearing with convex sphered outside diameter (fig a)
a Y-bearing housing, which has a correspondingly sphered but concave bore (fig b).
Y-bearing units are ready-to-mount, greased and sealed units which enable initial errors of alignment to be compensated for.

Y-bearing units consist of a housing, bearing and seal that is preassembled and greased at the factory. These ready-to-mount units can accommodate moderate initial misalignment but normally do not enable axial displacement of the shaft.
Y-bearing units offer a simple, cost-effective solution that can provide a number of benefits.
