Bearings on sleeves
Self-aligning ball bearings with a tapered bore
can be mounted on plain or stepped shafts
with an adapter sleeve († fig. 7) or on
stepped shafts with a withdrawal sleeve
(† fig. 8). Adapter sleeves are supplied complete
with a locking device. For add ition al
information about sleeves, refer to Bearing
accessories († page 1269).
Adapter sleeves are more popular than
withdrawal sleeves as they do not require axial
locating devices on the shaft. Therefore, only
adapter sleeves are listed together with the
suitable bearings in this catalogue.
When using sealed self-aligning ball bearings
on an adapter sleeve, the locking device
must not interfere with the seal. To avoid this,
use an appropriate SKF adapter sleeve assembly,
as listed in the product tables († page
564). Sealed bearings use either a standard
sleeve or an E design sleeve († fig. 9). Alternatively,
a spacer ring can be inserted between
the bearing and the lock washer.
