The concept
SKF SPEEDI-SLEEVE
To seal efficiently, radial shaft seals
must run against a smooth, round
surface – the seal counter face.
If the counter face becomes worn,
the seal will no longer be able to
fulfill its function, which is to retain
lubricant and to exclude contaminants.
Typically, the counter face becomes
scored when a contaminant particle is
caught under the seal lip and abrades
a track as the shaft rotates.

Shaft repair without sleeve
After removing the shaft from
machine:
• Re-metallise and grind shaft
• Machine shaft to smaller size
• Try and find a new seal lip wear spot
without removing shaft
Potential issues
•
•
•
•
•
•
Repair not concentric to shaft
Machine lead
Need new seal size
Long repair time
New seal rides in old groove
High cost to disassemble machine
Smaller shaft size

A simple idea…
… with an impressive effect
The SKF SPEEDI-SLEEVE has been
developed to solve the problem of worn
seal counter faces at shaft ends.
This thin-walled sleeve has a high quality
finish to provide an optimal counter face
for a radial shaft seal.
The sleeve is simply pushed in position
over the worn area providing a sealing
surface that is as good as a new shaft, if
not better.

Fast and easy
• no machining involved - the
sleeve is simply pushed in
position over the worn area
• costly downtime saved - the
original seal-size can be used
• the shaft becomes as good as
new, or even better

SPEEDI-SLEEVE removable flange
For applications where space is
limited, or multiple sleeves are
necessary, the flange can be
removed after the sleeve is set
in position.

Installing a SPEEDI-SLEEVE
A new seal counter face in a minute
The thin-walled SPEEDI-SLEEVE, with its high
quality finish and hardness for its purpose, which is
simply pushed in position over the worn shaft and
after installing a new seal, the shaft is as good
as new – if not better.
Remove the flange if necessary, is only done after
the sleeve has reached its final position.
The flange should be cut before assembly through
to the tear groove after which it can be peeled off
along the groove using a pair of pliers. If the flange
is not in the way when other parts are being
assembled and if it will not foul another component
in operation, it is recommended that it be left in
position.

From scored to restored in just a few minutes
Clean and measure the
diameter of the worn shaft and
mark the area where the sleeve
will cover the scored portion of
the shaft.
October 30, 2007 © SKF Group Slide 18
Place the SPEEDI-SLEEVE on
the shaft and then place the
special installation tool over the
sleeve.
Tap the installation tool with a
mallet until the sleeve is seated
on the shaft over the marked
area. Remove the installation
tool.

Large diameter wear sleeves
In applications where seal wear and shaft
damage can be expected, it is recommended
that the large diameter wear sleeves are
installed into the application already from the
outset.
LDSLV3
Type LDSLV3 is designed with a flange
to simplify final positioning of the sleeve
Type LDSLV4 has the same features as
type LDSLV3 but without a flange. LDSLV4
is intended for applications where a flange
could interfere with other components during
installation.
Both types are made of high quality
SAE 1008 carbon steel and chrome plated
to enhance the wear- and corrosion-resistance.
