Overview

EN 2130:2001 - "Aerospace series - Bearings, precision ball in corrosion resisting steel for instruments and equipment" - is a CEN technical specification for precision ball bearings in corrosion‑resisting steel with nominal bore diameters up to and including small instrument sizes. The standard sets required characteristics, inspection and test methods, qualification and acceptance conditions for bearings used in aerospace instruments and equipment. It is applicable wherever referenced in procurement, design or certification documents.

Key topics and requirements

  • Scope and product definition: Precision ball bearings in corrosion‑resisting steel for aerospace instruments (nominal bore diameter in the small instrument range covered by the product standard).
  • Materials and documentation: Chemical analysis or a certificate (EN 10204) from the semi‑finished product manufacturer is required.
  • Dimensional and environmental measurement conditions: Measurements are carried out at 20–25 °C and relative humidity <55 %, with bearings conditioned for at least one hour beforehand.
  • Running accuracy and clearances: Defines radial/axial running accuracy (Kia, Kea, Sia, Sea) and radial internal clearance measurement procedures.
  • Starting torque: Specifies starting torque test methods, controlled atmosphere/cleanroom conditions, lubricant and quantity requirements, and allowed reconditioning/retest practice.
  • Load ratings and static tests: Basic static load rating tests and their effect on starting torque are included.
  • Seals/shields and lubrication: Requirements for shields and seals (retention, sealing performance) and a normative Annex A that prescribes lubricant characteristics (ester greases and synthetic oils suitable for instrument use).
  • Magnetism: Limits for residual magnetism after demagnetization (value specified in the standard).
  • Qualification and acceptance: Qualification testing (non‑destructive and destructive) follows EN 3042 procedures; acceptance sampling plans reference ISO 2859‑1. Manufacturer issues a certificate of compliance (EN 10204) for each production batch.
  • Packaging and traceability: Packaging, anti‑corrosion protection, lubricant/packing dates and identity block marking requirements are defined.

Practical applications

  • Use this standard when specifying precision ball bearings for aircraft instruments, gyroscopes, sensors, cockpit instrumentation and other avionics/mechanical instruments where corrosion resistance and predictable torque/clearance behavior are critical.
  • It governs supplier qualification, production acceptance testing, incoming inspection by purchasers, and ensures traceability and documentation needed for aerospace procurement and certification.

Who should use EN 2130:2001

  • Bearing manufacturers and subcontractors producing corrosion‑resisting precision bearings for aerospace
  • Design and systems engineers specifying bearings for instruments and equipment
  • Quality assurance, procurement and acceptance inspectors in aerospace OEMs and suppliers
  • Test laboratories and certification authorities performing qualification and acceptance testing

Related standards

  • EN 3042 (quality assurance - qualification procedure)
  • EN 2079 / EN 3446 (product dimension/load standards for bearings with/without flange)
  • EN 10204 (types of inspection documents)
  • ISO 3290 (rolling bearing balls - dimensions and tolerances)
  • ISO 1132‑1, ISO 2859‑1 (tolerances and sampling procedures)

Keywords: EN 2130:2001, precision ball bearings, corrosion resisting steel, aerospace instruments, starting torque, radial internal clearance, qualification, acceptance testing, lubrication.
