High performance single-acting seal
Description
This compact rod/gland seal
provides optimum sealing
performance combined with smooth
operation and low levels of breakout
and dynamic friction. These features
are efficiently achieved by using a
PTFE sleeve supported by a
rectangular elastomeric energiser.
In operation, the rectangular energiser
helps to keep leakage to a minimum
by evenly supporting the PTFE sleeve,
preventing it from twisting or rocking in
the housing. Stable fluid film conditions
and consistent low friction values are
therefore maintained.
In addition, the profile of the PTFE
sleeve is designed to control leakage
by ensuring that the maximum possible
amount of residual fluid film is recovered
from the piston rod on the return stroke.
Due to the self-lubricating properties of
the running face of the seal, and its singleacting
profile, two seals may be fitted
in tandem to provide optimum leakage
control without the risk of inter-seal
pressure trapping.
Special features
• High performance single-acting seal
providing low wear and maintenance.
• Low dynamic and breakout friction for
instant response, smooth operation and
reduced power consumption.
• Rectangular energiser stabilises sealing
element during operation giving
optimum fluid retention and seal life.
• Should be used in conjunction with
Lionsele® B1 or B2 bearing strips (see
pages 45-46) to eliminate metal-to-metal
contact and other problems associated
with offset shafts.
Typical applications
Systems where instant response and
low power consumption are important
and leakage is unacceptable. Examples
include: hydraulic cylinders, mobile
hydraulics, injection moulding machines,
and downstroking presses.
Operating capabilities
• Maximum operating pressure:
40MPa (5802psi).
• Temperature range (standard materials):
-25°C to +120°C (-13°F to +248°F).
• Maximum surface speed:
5.0m/s (984fpm). For higher speeds
please consult our Technical
Support Team.
Materials of construction
Energiser
Standard material: medium nitrile (NBR)
Special materials: other elastomers to
suit operating conditions, including
fluoroelastomer (FKM) for high
temperature duties.
PTFE sleeve
Standard material: Fluolion? B60 bronzeloaded
PTFE.
Special materials: alternative grades
of Fluolion? PTFE to suit specific
applications.
Media capabilities
Standard materials are suitable for use
with most mineral-based hydraulic fluids,
and most fire-resistant fluids of the water/
oil or water/glycol types at temperatures
up to 120°C (248°F). Also resistant to
air, water and most lubricating oils and
greases. Where fire-resistant fluids are
used, it is essential to advise our Technical
Support Team of the type and designation
due to the effects that can occur with
different grades.
Special materials considerably extend
the range of application in terms of
temperature, fluid compatibility and
abrasion resistance. Please ask our
Technical Support Team for further
information.
