Parker PK502HLL01 Cylinder Seals

Here is an introduction to Parker hydraulic and pneumatic cylinder seals

The main seals used in Parker hydraulic and pneumatic cylinders include:

1. O-rings:

– There are piston O-rings and cylinder barrel O-rings.

– Materials used include nylon and rubber for their wear resistance.

– They are used to prevent fluid leakage and keep the fluid contained between the piston and cylinder.

2. U-cups (spring energizers):

– Used in conjunction with O-rings to keep them firmly against the piston or cylinder barrel surface to form a seal.

– Made from durable stainless steel.

3. Wiper seals (O-rings):

– Located between the piston rod and seal end cap to prevent oil leakage.

– Made from wear-resistant rubber materials.

4. Backup rings:

– Located between the piston and piston rod to provide cushioning and sealing functions.

– Made from nylon or rubber for wear resistance.

5. Other auxiliary seals.

Applications: Suitable for various hydraulic and pneumatic cylinders. Proper material selection based on working conditions to ensure long-term reliable operation. Regular replacement of worn seals can extend service life.

In summary, these are the main types of seals used in Parker hydraulic/pneumatic cylinders and their functions. Using high-quality seals effectively prevents fluid leakage and ensures normal cylinder body operation. Proper maintenance of seals is important for optimal performance.
