mounting and Slots or recesses in the shaft to apply
withdrawal tools
dismounting

Particularly when large bearings are
involved, SKF recommends that during the
design stage you make provisions to facili-
tate mounting and dismounting, including:

• slots or recesses machined in the shaft or
housing shoulders so that withdrawal
tools can be used (ig. 8)
• threaded holes in the housing shoulders Fig. 9
so that bolts can be used for dismounting Threaded holes in the housing to push
(ig. 9) bearing with bolts from its seat
• oil supply ducts and distribution grooves in
the shaft to enable the oil injection method
to be used (ig. 10)
Recommended dimensions for oil sup-
ply ducts and distribution grooves are
listed in table 22, and for threaded holes
in table 23 When using the oil injection
method, Ra should not exceed 1,6 μm
