Locating on the shaft
Fig. 1
There is a choice of five different methods 1
(† fig. 1) by which an SKF Y-bearing unit can
be located onto the shaft:

• Grub screws (a). This method enables very
easy mounting and dismounting, even
if space is limited. This locking method is
typically used in applications where the shaft
a alternates direction of rotation.
• Eccentric locking collar (b). This locking method
is typically used for applications where the
shaft rotates in one direction only. It can be
used for alternating directions when loads
and speeds are low.
• Adapter sleeve locking (c). This method enables
a concentric locking of the Y-bearing unit on
the shaft and is appropriate for alternating
as well as constant direction of rotation.
b • SKF ConCentra locking (d). This method
enables true concentric locking on the shaft.
It is appropriate for alternating, as well as
constant direction of rotation. For additional
information about SKF ConCentra ball bear-
ings and units refer to the dedicated chapter
on page 247.
• Interference fit (e). The use of an interference
fit is only available for Y-bearings in the
17262(00)-2RS1 and 17263(00)-2RS1 series.
c These bearings and the required housings
have to be ordered separately.
