Overview
EN 3048:2001 - Aerospace series - defines the dimensions, loads and characteristics of spherical plain bearings made from corrosion resisting steel with a self‑lubricating liner. It covers the light series - elevated load at ambient temperature, intended for use in fixed or moving parts of aircraft structures and control mechanisms. Bearings covered by EN 3048 are designed to operate in the temperature range –55 °C to +163 °C, and may be supplied with or without swaging grooves.
Key topics and technical requirements
- Scope and configuration: Specifies geometry, tolerances and mass for standard sizes (nominal bore diameters from approximately 12 mm to 50 mm are tabulated).
- Dimensions and tolerances: Drawings, dimensional tables and tolerance definitions are provided (tolerances reference ISO 1132‑1).
- Loads and torques: Tabulated permissible static and dynamic radial/axial loads and starting torques for each nominal size; special note that push‑out loads can be reduced for bearings with swaging grooves.
- Materials and hardness:
- Inner ring: steel per EN 2030, hardness 55–62 HRC.
- Outer ring: steel per EN 2539, hardness 28–37 HRC before swaging.
- Liner: self‑lubricating, low‑friction, wear‑resistant material conforming to EN 2755.
- Surface treatment (inner ring only): Options include chromium plating (15–50 µm) per EN 2132 and passivation per ISO 8075; codes identify treatments on the part designation.
- Designation and marking: Standardized identification block and technology codes (bonded or moulded/injected liner) plus marking requirements according to EN 2424.
- Operating conditions: Intended for elevated load at ambient temperature and aerospace service conditions.
Practical applications
- Use in aircraft control mechanisms, hinges, bearings in landing gear subassemblies, flight control linkages and other structural joints requiring spherical articulation.
- Suitable where corrosion resistance, self‑lubrication and predictable load ratings are required under aerospace environmental and temperature ranges.
- Enables consistent procurement, interchangeability and traceability for aerospace manufacturers and maintenance organizations.
Who will use EN 3048:2001
- Aircraft designers and structural engineers specifying bearing components.
- Procurement and quality engineers ensuring supplier compliance.
- Maintenance, repair and overhaul (MRO) teams selecting replacement parts.
- Bearing and component manufacturers producing aerospace spherical plain bearings.
