Document Overview:
This technical document provides detailed specifications and reference data for Borrelly's ONDUFILTM spring washers, including standard and stainless steel variants. It includes product codes, dimensions, mechanical properties, and installation guidelines.

1. Product Identification and Variants:
- ONDUFILTM is a registered trademark of Borrelly.
- Product references ending with "XT" indicate standard XC 75 material washers.
- For stainless steel washers, replace "XT" with "IX" at the end of the reference.

2. Dimensional Specifications:
- The tables list bore diameter (B), outer diameter (A), wire cross-section dimensions, and other key measurements.
- Dimensions are given in millimeters (mm).
- Adjustments in bore diameter (A) and clearance for shaft diameter (B) are noted, with specific tolerances (e.g., clearance for shaft diameter B minus 0.5 mm or 1.0 mm depending on the table).

3. Mechanical Properties:
- Stiffness values are provided in daN/mm (decaNewton per millimeter), indicating the spring washer's resistance to deformation.
- Load capacity (P1) is given in daN with a tolerance of ±10%.
- Number of waves and free height (Ho) are specified, which relate to the washer's spring characteristics.

4. Installation and Usage Notes:
- Maximum compressed height is indicated for certain washers.
- Height fitting (H1) values are provided to assist with proper installation.
- The document notes that data is for information only and subject to change.

5. Product Range Details:
- The document includes a standard ONDUFILTM multi-turn spring washer range available in XC 75 and stainless steel.
- Multi-turn washers have additional parameters such as number of waves per turn, number of turns, and working height (H1).

6. Contact Information:
- Borrelly contact details are provided for further inquiries.

Summary of Critical Parameters:
- Material type indicated by suffix (XT for XC 75, IX for stainless steel).
- Bore diameter and outer diameter critical for fitting.
- Wire cross-section dimensions affect stiffness and load capacity.
- Stiffness and load ratings guide selection for pre-stressed ball bearings.
- Number of waves and free height influence spring performance.

This document serves as a technical reference for engineers and purchasers to select appropriate ONDUFILTM spring washers based on mechanical and dimensional requirements.
