Aerospace series - Ball bearings, rigid in corrosion resisting steel cadmium plated, for control cable pulleys - Dimensions and loads

This European Standard specifies the characteristics of ball bearings fitted with shields of seals, for aircraft control cable pulleys.

Luft- und Raumfahrt - Hartkugellager aus korrosionsbeständigem Stahl, verkadmet, für Seilrollen für Steuerseile - Maße und Belastungen

Diese Europäische Norm legt die Merkmale von Kugellagern mit Deckscheiben oder Dichtscheiben zum Einbau in Seilrollen für Steuerseile von Luftfahrzeugen fest.
Die in dieser Norm definierten Seilrollenkugellager sind in einem Temperaturbereich von 54 °C bis 150 °C einsetzbar.
Der Temperaturbereich hängt jedoch vom eingesetzten Schmierfett ab:
   Höchstdruckfett, auf Basis von Ester (Code A), Betriebsbereich 73 °C bis 121 °C oder
   Höchstdruckfett, auf Basis synthetischer Kohlenwasserstoffe, für den allgemeinen Gebrauch (Code B), Betriebsbereich 54 °C bis 177 °C (vergleiche EN 2062);
Der Einsatzbereich ist unter Verwendung von Code -A-Schmierfett auf 121 °C begrenzt.

Aeronavtika - Kroglični ležaji iz korozijsko odpornega in kadmiranega jekla za kolute krmilnih kablov - Mere in obremenitve

Ta evropski standard določa značilnosti krogličnih ležajev, opremljenih z zaščito s tesnili, za kolute krmilnih kablov v letalu. Kolutni ležaji, opredeljeni v tem standardu, se uporabljajo v razponu od –54 do 150 °C. Vendar se morajo podmazovati z naslednjimi mastmi: – mast pod zelo visokim tlakom, vrste ester (koda A), območje delovanja od –73 do 121 °C ali – mast pod zelo visokim tlakom, sintetični ogljikovodiki, splošni namen (koda B), območje delovanja od –54 do 177 °C (glejte EN 2062); njihovo področje uporabe je pri podmazovanju z mastjo kode A omejeno na 121 °C.

Overview

EN 3182:2012 - part of the Aerospace series - defines ball bearings, rigid in corrosion-resisting steel cadmium plated, for control cable pulleys. This CEN standard specifies dimensions, tolerances, clearances, loads and marking for bearings used in aircraft control cable pulley assemblies. It covers bearings fitted with shields or seals, typical bore sizes (codes 05–15 correspond to nominal bores 5 mm to 15 mm), and the environmental/operational limits for use in aerospace systems.

Key Topics and Requirements

• Scope & temperature: Bearings are qualified for use from −54 °C to 150 °C. When lubricated, field limits depend on grease type:
  • Code A (ester high‑pressure): operational to 121 °C (lubricant range −73 °C to 121 °C)
  • Code B (synthetic hydrocarbon high‑pressure): operational to 177 °C (lubricant range −54 °C to 177 °C)
• Dimensions & tolerances: Detailed tabulated values for bore, outside diameter, width, tolerances, clearances, starting torque and permissible static radial load. Configuration drawings (code options) and assembly with shields or seals are defined.
• Surface finish: Raceway and rolling elements Ra = 0.2 µm; bore, side faces and cylindrical outer surface Ra = 0.8 µm.
• Materials & hardness: Inner ring, outer ring and balls: steel EN 2030 (hardened and tempered, ≥ 58 HRC). Shields: corrosion-resisting material. Seals: PTFE or PTFE with glass‑fibre reinforcement.
• Surface treatment: Cadmium plating (5–12 µm) applied to specified surfaces per EN 2133; note that bore and raceway are not cadmium plated. De‑embrittlement heat treatment required within 16 hours after plating.
• Performance limits: Runout, starting torque and permissible static radial loads are specified and measured on bearings not fitted to pulleys.
• Designation & marking: Standardized identity block format (includes standard number, grease code, seal/shield code and size). Manufacturer marking and position rules are stipulated.

Applications and Users

• Primary application: aircraft control cable pulleys (flight control systems, actuation linkages).
• Typical users:
  • Aerospace OEMs and component designers specifying bearings for cable pulley assemblies
  • Procurement and quality engineers ensuring compliance with EN 3182:2012
  • Maintenance, repair and overhaul (MRO) organizations selecting replacement bearings
  • Certification and qualification teams validating material, plating and lubrication requirements

Related Standards

• EN 2030 - Steel FE‑PM3501 (X105CrMo17) for bearing rings and balls
• EN 2133 - Cadmium plating requirements and passivation
• EN 2062 - Technical specification for fully non‑metallic body pulleys with bearings (referenced for supplied bearings)

EN 3182:2012 is a focused standard for designers and suppliers of aerospace control cable pulley bearings, providing precise dimensional, material and performance requirements to ensure safe, reliable operation in aircraft systems.
