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
- The nature of appliEion
- Fluid to be sealed
Minimum , maximum and working fluid pressures
Minimum , maximum and working teperatures
Shaft speed and lubricant used
Estimated toal annuad demand and weekly call-off
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.
