Basic design
SKF withdrawal sleeves († fig. 11) are slit.
Sleeves with a bore diameter ≤ 190 mm (size
≤ 40) are phosphated. Larger sleeves are
coated with a solventless rust inhibitor.
The nut required to dismount a withdrawal
sleeve must be ordered separately. Appropriate
sizes of nuts are listed in the product
tables.
Withdrawal sleeves listed in this catalogue
constitute the basic SKF assortment. For
larger sizes (bore diameter ≥ 1 060 mm), contact
SKF.
Variant for oil injection
Withdrawal sleeves with oil supply ducts and
distribution grooves, which enable use of the
oil injection method to mount and dismount
bearings (AOH series, † fig. 12), are available.
These sleeves have two oil supply ducts
at the threaded end that feed the distribution
grooves. The distribution grooves are in the
circumferential and axial directions, on both
the outside surface and the sleeve bore.
Thread details for the oil supply ducts are
listed in the product tables.
SKF withdrawal sleeves with a bore diameter
≥ 200 mm (size ≥ 44) are equipped with
the necessary ducts and grooves as standard.
For sleeves with a bore diameter ≥ 150 mm
(size ≥ 32), these features are available on
request.

Lubrication Products or visit skf.com/mapro.
