Product Description

The high pressure piston rod seals provided by Ruichen are composed of PTFE sealing rings and O-shaped rubber rings, which are specially used for one-way sealing of hydraulic reciprocating motion. They are divided into RC01-RC14 series according to the matching O-rings. When working, the O-ring provides radial force to compensate for the wear of the sealing ring, and the thin lip design of the sealing ring has good fit. The two work together to create a good sealing effect.

Our high pressure piston rod seals are widely used in injection molding machines and die-casting machines in industrial hydraulic systems, excavators and loaders in engineering machinery, hydraulic parts in automobile manufacturing and maintenance, landing gear and actuators in aerospace, and hydraulic steering gears and windlasses in shipbuilding. They can effectively ensure the stable operation of hydraulic systems and avoid leakage.

Product features and applications:

Features:

1. High pressure piston rod seals can be used for both hydraulic and pneumatic applications.

2. The sealing performance is always good whether it is high or low pressure sealing conditions.

3. Low friction, small starting resistance, smooth movement, equal dynamic and static friction, no creeping.

4. The seal has a long life, suitable for oil-free lubrication sealing.

5. Small structural space and easy installation and maintenance.
