Insert bearings (Y-bearings)
Y-bearing with a tapered bore on an adapter sleeve
Insert bearings (SKF Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
Designs and variants
Insert bearings typically have a spherically shaped (convex) outside surface and an extended inner ring (fig. 1) with different types of locking device. The various insert bearing series differ in the way the bearing is locked onto the shaft:
with grub (set) screws (fig. 2)
with an eccentric locking collar (fig. 3)
with SKF ConCentra locking technology (fig. 4)
with an adapter sleeve (fig. 5)
with an interference fit (fig. 6)
Insert bearings with an inner ring that is extended on both sides run more smoothly, as the extent to which the inner ring can tilt on the shaft is reduced.
The standard SKF insert bearing assortment presented in this section also includes application-specific variants, such as:
bearings made of stainless steel or with zinc-coated rings for the food industry (Insert bearings with grub screws, SKF Food Line ball bearing units)
bearings for agricultural applications (SKF ball bearing units for agriculture applications)
Lubrication
SKF insert bearings are supplied capped on both sides and are greased.
