For easy mounting –<br />
adapter and withdrawal<br />
sleeves<br />
Generally <strong>the</strong> bearings with a tapered<br />
bore incorporated in <strong>SNL</strong> <strong>plummer</strong><br />
<strong>block</strong> <strong><strong>housing</strong>s</strong> are mounted on<br />
smooth or stepped shafts with <strong>the</strong> aid<br />
of an adapter sleeve or, on stepped<br />
shafts only, a withdrawal sleeve. These<br />
sleeves are produced by SKF in appropriate<br />
sizes for <strong>the</strong> range of bearings<br />
which can be used in <strong>SNL</strong> <strong><strong>housing</strong>s</strong>.<br />
The adapter sleeves are <strong>the</strong> more<br />
popular as <strong>the</strong>y are more versatile and<br />
are easier to mount.<br />
Adapter sleeves<br />
These are slotted sleeves with a<br />
tapered outside diameter. The sizes<br />
used with bearings for <strong>SNL</strong> <strong><strong>housing</strong>s</strong><br />
have an external taper of 1:12 and are<br />
supplied complete with lock nut and<br />
locking washer. Their dimensions are<br />
in accordance with ISO 2982-1:1995.<br />
When using adapter sleeves on<br />
smooth shafts it is possible to locate<br />
<strong>the</strong> bearing at any position on <strong>the</strong> shaft<br />
and no additional axial location is<br />
required.<br />
Withdrawal sleeves<br />
These are also slotted sleeves with<br />
a tapered outside diameter. The sizes<br />
used with bearings for <strong>SNL</strong> <strong><strong>housing</strong>s</strong><br />
have an external taper of 1:12. Their<br />
dimensions are in accordance with<br />
ISO 2982-1:1995.<br />
Bearings on withdrawal sleeves must<br />
be mounted against a fixed abutment,<br />
e.g. a shaft shoulder. The withdrawal<br />
sleeve must be secured in position<br />
after it has been pressed into <strong>the</strong><br />
bearing bore by a lock nut or end plate<br />
on <strong>the</strong> shaft. The nuts are not supplied<br />
with <strong>the</strong> sleeves.<br />
