Document Overview

This document provides indicative profiles and technical references related to sealing joints, piston seals, rotary seals, sliding bushes, wear rings, and machined parts. The data is given for information purposes only, with a reservation of rights to modify content without prior notice.

1. General Information and Disclaimer

• Profiles and data are indicative and subject to change by Techné without prior notice.
• Materials and profile references are standardized for various sealing and joint applications.

2. Joints and Seals

This section lists various types of standardized joints and seals, including rod joints, piston seals, rotary seals, and wiper seals. Each profile is identified by a family code, profile name, material, and size code.

• Rod Joints: Includes BAE T1 to T5, clamps, D-rings, O-rings, and other profiles with materials such as NBR, FKM, EPDM, VMQ, CR, HNBR, ACM, AEM, PU, and PTFE.
• Piston Seals: Profiles like CPDE, CPPU, CPSE, JP series, and others with corresponding material codes and size references.
• Rotary Seals: Wellen dichtringe (shaft seals) with various profiles such as ½E DL, AE DL, AEX DL, AN DL, and others, including right helix, left helix, and bi-directional helix types. Materials include stainless steel (AISI 304) and elastomers.
• Wiper Seals: Profiles such as RADL, TDE SL, TDJ SL, and others designed to prevent contamination.

3. Materials and Codes

The document uses standardized material codes for elastomers and polymers:

• N: NBR (Nitrile Butadiene Rubber)
• F: FKM (Fluoroelastomer)
• E: EPDM (Ethylene Propylene Diene Monomer)
• V: VMQ (Silicone Rubber)
• CR: Chloroprene Rubber
• H: HNBR (Hydrogenated NBR)
• AC: ACM (Polyacrylate Rubber)
• AE: AEM (Ethylene Acrylic Rubber)
• PU: Polyurethane
• P: PTFE (Polytetrafluoroethylene)

4. Profiles and Size Codes

Each profile is associated with a family number, profile name, material, and size code. Examples include:

• BAE T series (80)
• JT4 series (01)
• PU series for piston seals (40, 70)
• DL, SL, and AEX series for rotary seals (22)
• Wear rings and sliding bushes (21, 69)

5. Machined Parts

The document also references machined parts with codes such as A1 to A17, S1 to S20, K1 to K80, R1 to RST, and others. These parts correspond to specific profiles and materials used in sealing and joint assemblies.

6. Key Recommendations and Limitations

• Profiles and materials are provided for guidance and may be updated without notice.
• Selection of profiles should consider material compatibility, size, and application type (rod, piston, rotary, wiper).
• Material codes must be referenced carefully to ensure correct elastomer or polymer selection for operating conditions.

7. Summary of Profile Families

Conclusion

This technical document serves as a comprehensive reference for various sealing profiles, materials, and machined parts used in industrial sealing applications. It emphasizes the importance of material selection and profile identification for proper sealing performance. Users should note the disclaimer regarding possible updates and verify current data before application.
