Product catalog summary

Document Overview:
This technical document outlines various sealing applications and standards for hydraulic and pneumatic cylinders, focusing on achieving high static and dynamic sealing efficiency with low friction. It covers external and internal sealing systems, specific sealing solutions for telescopic and multi-stage cylinders, and guidelines for improved sealing performance.

1. Application Limits and Design Considerations

The document specifies application limits for standard sealing profiles used in hydraulic and pneumatic cylinders. It emphasizes the importance of selecting seals that provide high efficiency in both static and dynamic conditions while maintaining low friction to ensure optimal performance.

2. External and Internal Sealing Systems

Details are provided on external and internal sealing systems designed for hydraulic cylinders requiring high static and dynamic sealing efficiency with low friction. These systems are tailored to different cylinder types and operational requirements.

3. Sealing Solutions for Telescopic Cylinders

  • Standard Seals: Solutions for telescopic cylinders with low installation grooves and excellent stick-slip properties.
  • Multi-Fold Applications: Sealing systems designed for multi-fold applications in side sealing configurations, ensuring reliable performance in complex cylinder designs.

4. Rod and Piston Sealing in Side Sealing Configurations

The document introduces improved versions of rod and piston seals with enhanced sealing efficiency. These seals are easy to fit without the need for gap extrusion or sliding ring wear during operation. They can be combined with bearing types (e.g., type F1) to optimize performance.

5. High-Pressure and Low-Friction Sealing

  • Seals with radial drillings for high-pressure cylinders and pistons.
  • Standard low-friction seals for rods and pistons.
  • Heavy-duty series seals designed for low-friction operation in demanding environments.
  • Step profile seals for low-friction single-acting cylinders.

6. Performance Values and Recommendations

The document highlights maximum pressure values for modified sealing elements or modified installation grooves. It stresses that these maximum values should not be exceeded simultaneously to avoid compromising seal integrity and cylinder performance.

7. Summary of Best Practices

  • Select seals based on application type (hydraulic or pneumatic) and operational pressure requirements.
  • Use improved sealing designs to reduce friction and wear, enhancing cylinder lifespan.
  • Combine seals with appropriate bearing types to optimize sealing efficiency and mechanical stability.
  • Adhere strictly to maximum pressure limits and installation guidelines to ensure reliable operation.

Note: The document contains technical tables and diagrams illustrating seal profiles, installation grooves, and pressure ratings, which provide critical data for selecting and applying seals correctly.
