Overview - ISO 9760:2000 (Aerospace fork-ends)
ISO 9760:2000 is an international aerospace standard that defines the characteristics, dimensions and loads for fork-ends made of corrosion‑resistant steel swaged onto aircraft control wire rope for use with rolling bearings. Published in 2000, the standard covers configuration, dimensional drawings, mass and breaking‑load data, material guidance and required surface treatments, and includes a normative Annex A mapping equivalent national materials and treatments.
Key topics and technical requirements
- Scope and configuration: Specifies fork‑end geometry and the required views/notations (see Figure 1 and Table 1) - dimensions are given in millimetres and surface roughness in micrometres.
- Dimensions, loads and masses: Dimensions and load ratings are standardized to ensure interchangeability and reliable bearing connections; designers must use the values provided in the normative table and figures.
- Material: Fork‑ends are made from corrosion‑resistant steel, with material selection guided by Annex A (correspondence tables to national standards).
- Surface treatment: Accepts passivation (code P) per ISO 8074 or peening (code G) in accordance with Annex A/SAE guidance; surface finish requirements are indicated on drawings.
- Designation and marking: Each fork‑end must carry a defined identity block and manufacturer’s marking located as shown in the standard’s figure; marking method is at manufacturer’s option.
- Normative references and technical specification: Incorporates related standards (e.g., ISO 2020‑1 for preformed wire rope dimensions, ISO 10955 for end fittings) and treats Annex A as normative for material equivalence.
Applications and who uses ISO 9760
- Aerospace OEMs and tier‑1 suppliers specifying or producing control cable assemblies and end fittings for actuation, flight controls, and control linkages.
- Design and mechanical engineers who need standardized fork‑ends for rolling bearings to guarantee fit, load capacity and corrosion resistance.
- Quality, procurement and maintenance teams ensuring parts conformity, traceability and appropriate surface treatment for in‑service durability.
- Certification and regulatory bodies referencing standard dimensions and materials during approvals and airworthiness assessments.
Practical uses include part specification in engineering drawings, supplier qualification, procurement of swaged fork‑end assemblies, and ensuring compatibility with aircraft control wire rope systems.
