o-ring and seals for dynamic applications are manufactured
by Gmors for use in both linear as well as reciprocating
functions in hydraulic systems. Products include rotary
shaft seals, rod seals, piston seals, wipers, back-up rings,
cushions seals and more.
o-rings form a critical part of the sealing mechanism of
cylinders as a leakage preventer. During operation, they are
subjected to high temperatures and pressure extremity. Gmors
seals and o-rings are sold to distributors and heavy
machinery manufacturers throughout the world in industries
as diverse as mining, food processing, oil and gas,
agricultural, material handling and power generation
O-Ring Designs in Hydraulic
The sealing requirements for
hydraulic equipment may be static, reciprocating, rotary,
oscillating and so on.
Static Sealing Applications
are used where movements of mating components relative
to each other is not expected. Typically, static seals are
found below the head of bolts or rivets, in connections for
piping or related applications. The static nature of such
seals still has to allow for minor expansion due to heat, or
movements due to vibration.
Reciprocating Seals are
designed to allow for movement of mating parts along the
axis of the shaft in a hydraulic cylinder. The reciprocating
movement causes the hydraulic o-ring or seal to roll or
slide back and forth. A common use of the reciprocating seal
would be found in the hydraulic piston.
The inner and outer components
of the seal assembly in oscillating seals moves a
manner of an arc around the axis of the shaft. In the
process, the components relative to the hydraulic o-ring or
seal is typically rotated. In the case where movement of the
arc is greater than 360 degrees (example: Repeated turning
of the handle of valves during operation), the oscillating
seal differs from the rotary seal by way of the opposite
direction of the returning arc. In faucet valve stems, the
oscillating seals can be found in the form of an o-ring
A single-directional turning
around the axis of the shaft by either the inner member, or
the outer member of the sealing component distinguishes the
rotary seal. In this application, turning is
reversible but is distinguished from the oscillating seal in
that the start and stop phase upon short arc movements is
not allowed for.
