903-20903 JS190 Jcb Hydraulic Cylinder Seal Kits Anti Solvent OEM
Acceptable
Seal ring
◎Main seal, used in multi-stage cylinders, strong tear resistance,
high tensile strength, special impact resistance, not easy to tear
and damage;
◎ Good elasticity and good sealing effect, more suitable for coal
and mining industry;
◎Opening the secondary lip of the ring to support the function. At
the same time, a small amount of oil film extends from the annular
lip of the opening to improve the lubriEion condition of the
subsequent order;
◎With the drum ring, it is safer.
Advantages:
1, Focus on the development and manufacture of hydraulic seals for
years.
2, A great number standard parts in stock .
3, Customized seasl service .
4, CNC Machining Seals without mould cost ,fast dispatch.
5, All of seals the inner diameter from 0.2mm to 3500mm can be
produced.
6, Seals solutions and technical support.

1. Product introduction
The availability of highly developed nitriles resistant sa to oil
water and many other fluids has widened the field of unit seal
appliEion to a great extent , and provided precise contions of
machining accuracy finish and lubiEion are maintained in the
mechaisms to which these seals are applied they are capable of
giving excellent service within a wide range of temperatures and
speed conditions.
It is hoped the information given here will help the designer and
user to choose the correct type of sealing unit for his appliEion
,A publiEion of this kind cannot cover every aspect of fluid
sealing ,nor can it answer every puery which is likely to arirsre
,When enpuiring please state

3.The Role of Each Part
A. Lip end (sliding surface): The lip end is in the shape of a wedge and presses the shaft
surface at the end to seal the fluid.
B. Sealing lip: It is a flexible elastomer, designed to ensure that it can
maintain a stable sealing effect under the influence of mechanical
vibration and pressure fluctuations of the sealing fluid, and
maintain a stable contact state with the shaft surface at the end
of the lip effect. In addition, the spring can increase the
pressing force of the sealing lip on the shaft, which prevents the
intrusion of dust.
C. Dust-proof lip: The dust-proof lip is an auxiliary lip that is not connected to
the spring, and plays the role of preventing dust intrusion.
D. Fitting part: While fixing the oil seal to the cavity hole, the fitting part
plays the role of preventing fluid leakage and intrusion from the
contact surface between the outer peripheral surface of the oil
seal and the inner surface of the cavity. In addition, the metal
skeleton plays the role of fixing the oil seal on the cavity and
maintaining the matching force.
