SKF - Industrial Shaft Seals

Designs and features
SKF wear sleeves for heavy industrial appli cations
are available in two designs: the LDSLV3 with
a flange († fig. 9) and the LDSLV4 without a
flange († fig. 10). Both designs are made of
SAE 1008 chromium-plated carbon steel to
enhance wear and corrosion resistance. Other
sleeve materials can be provided to meet the
application’s specific demands. The sleeve outside
diameter is specially ground to provide a
pre cision counterface surface for the seal. The
wall thickness of the standard sleeves is
2,39 mm (0.094 in.).
LDSLV3 is designed with a flange to simplify
final positioning of the sleeve. The width of the
counterface surface for the seal is 6,35 mm
(0.25 in.) narrower than the total width of the
sleeve. The flange adds a nominal 25,4 mm
(1 in.) over the shaft diameter. The flange height
is 12,7 mm (0.5 in.) for all sizes. Note that force
should never be applied directly to the flange
when installing an LDSLV3.
LDSLV4 has the same features as LDSLV3 but
has no flange. LDSLV4 is intended for appli cations
where a flange could interfere with other components
during installation, or where a wider
seal counterface surface is required.
