Shaft ‘Wear Sleeves’
Sleeve is a highly engineered metal sleeve used on worn out
or new shafts.
a groove is worn into the Seal contact area of the Shaft,
an effective Sealing cannot be guaranteed on that shaft even
if leaking Seal is replaced by a new one. Paul Components
offers metal sleeves, which can restore the shaft surface
and eliminate the need to remetalise and regrind or replace
the surface area. Once it is in place, it provides a Sealing
surface that is superior to the most original shaft finishes
Digging a serious problem
that rotate on high speeds like Crankshafts experience shaft
polishing friction due to contact between rotating shaft &
Seal. As demands increase in the Sealing environment, wear
can accelerate. Dust, heat, dirt, shaft speed & lack of
lubrication can all cause a Seal lip to groove the shaft.
The ultimate result is a leak.
can be done with the help of special, inexpensive tool. It
needs no special shaft preparation or machining before installation.
Each sleeve is build with a removable installation flange
to allow ”pull on” installation.
the installation is done without removing the shaft it leads
to reduced equipment downtime. After fitting the sleeve, flange
can be torn through tear groove (Pre-cut line) by prying the
flange away from the Seal surface horizontally along the shaft
axis after the sleeve position.
can be removed either by applying some heat which will cause
the sleeve to expand & come out or can be ripped with
a pair of wire cutters by using the twisting motion at the
start of flange. After removal it can be replaced in a same
way as a new Sleeve.
not only freshens the grooved area but can also undertake
rust prevention since it is made of corrosion resistant material.
The Seal contact surface is factory finished to 10-20 micro
inches with machine lead angle of 0 ± 3 minutes.
Easy to use; saves labour & downtime cost of repairing
worn out shafts. Requires no change in Seal size due to
its thin walls, can be supplied to suit shafts of various
sizes upto 8” O.D.
Boon to customer as it gives trouble free life after O.E.M.
warranty period; adds to reputation of O.E.M.; Advantage
from marketing point of view.
Extends long life to Seal. Available in kits consisting
of Seal & machine sleeve.
Corrosion resistant –Protects Seal from leaking due
to shaft rusting in humid environments.
Does not require expensive machining of shaft. Cost can
be cut down on expensive shaft finishing & surface treatment.
