Cavets, Cautions & Correct
Usage Tips
Never Do:
Purchase a new Seal precisely
the same size as the old Seal that is being replaced.
Because all Seals shrink or swell with time / usage and
vary from its original installed size.
Always Do:
Use a set of Vernier Callipers
to measure the parts that will house the Seal and get
the Seal designed for that precise groove size.
Ensure that the Seal housing
has excellent surface finish, which is a vital component
for good sealing performance, low friction and durability.
Provide the Seal supplier
correct dimensions of: the shaft's outer diameter / the
required Rod Seal's inner diameter, the housing bore
diameter / the Piston Seal's outer diameter, and the
relevant radial cross section.
Remember:
Hydraulic Seals are designed for
reciprocating motion in high-pressure dynamic applications
in hydraulic cylinders. Compromising on quality could
prove fatal for your projects.
A Rod Seal is press-fitted
into a housing bore, with the sealing lip contacting
the shaft.
A Piston Seal is fitted
onto a shaft, with the sealing lip contacting the housing
bore.
The most common
causes of Seal failures are:
Wrong size.
Damage sustained during installation (if proper installation tools& methodology
are not used).
Faulty accommodation of
Seal (bad machining / cracks / scratches)
Technologically correct Seals,
installed into well-made Components, can give you many
cycles of trouble-free service.
