Y-bearings

Designs Fig. 1

SKF Y-bearings, which are usually referred to as
insert bearings, are basically sealed deep groove
ball bearings in the 62 and 63 series, with a
convex outer ring. These bearings are manufac-
tured in a number of different series and sizes
and are available with a standard inner ring or
an inner ring that is extended on one or both
sides († fig. 1).
The various insert bearing series differ in the
way the bearing is located onto the shaft. The
most common methods use any one of the
following:

• grub (set) screws († fig. 2)
• eccentric locking collar († fig. 3)
• adapter sleeve († fig. 4)
• interference fit († fig. 5) Fig. 2
• SKF ConCentra locking († fig. 6)

The standard SKF assortment includes Y-bearings
made of rolling bearing steel as well as stainless
steel and Y-bearings with zinc-coated
components.
