Document Overview:
This document provides technical specifications and reference data for Borrelly standard and stainless steel waved spring washers, specifically the CN STANDARD XC 75 series. The data is intended for informational purposes and is subject to change.

1. Product Identification and Reference Codes:
- Each washer is identified by a unique reference code starting with "PDD" or "PCD" followed by numerical and alphabetical characters.
- For stainless steel washers, the suffix "XT" in the reference is replaced by "IX".
- References include additional codes indicating compatibility with bearing types (e.g., EL3-623, 6000 series, 6200 series).

2. Dimensional Specifications:
- Bore diameter ranges from 10.00 mm up to 400.00 mm.
- Material thickness varies between 0.15 mm and 2.00 mm depending on the washer size.
- Flat diameters (outer diameter OD and inner diameter ID) are provided for each washer.
- Approximate free height and free diameter values are listed, indicating the washer's unloaded dimensions.

3. Mechanical Properties:
- Mean stiffness values are given in daN/mm, indicating the spring force per unit deflection.
- Load capacities are specified as P(H1) and P(H2) in daN, representing working loads at different heights.
- Working heights H1 and H2, along with parameters e and Ho, define the operational dimensions under load.

4. Product Variants and Features:
- Washers are available in standard and stainless steel versions.
- Variants include different finishes or treatments indicated by codes such as AF (possibly anti-friction) and NF.
- Some washers are associated with specific bearing series (e.g., 6000, 6200, 6300, 6400 series).

5. Usage and Availability:
- The washers are stocked and available for immediate supply.
- The data is non-binding and provided for guidance only.

6. Contact Information:
- Manufacturer contact details include telephone and fax numbers and a website URL.

Critical Information and Recommendations:
- When selecting a washer, ensure the correct reference code is used, especially noting the suffix change for stainless steel.
- Verify dimensional compatibility with the intended bearing or application.
- Consider the mean stiffness and load ratings to ensure the washer meets mechanical requirements.
- Note that all values are approximate and subject to change; confirm with the manufacturer for critical applications.

This structured summary captures the essential technical data, product identification, mechanical parameters, and usage notes for Borrelly waved spring washers as presented in the document.
