Overview

EN 4534-2:2016 is a European aerospace standard that specifies the dimensions, loads and general characteristics of plain bushes made from aluminium alloy with a self‑lubricating liner for elevated load applications - Inch series. The bushes are intended for use in fixed or moving parts of aircraft structures and control mechanisms and are qualified for the temperature range −55 °C to 121 °C.

Key topics and requirements

• Scope & configuration: Defines bush geometry, chamfers, radii and dimensional layout (figure and tables). Dimensions apply after surface treatment and are given in millimetres with inch equivalents.
• Materials:
  • Bush body: aluminium alloy per EN 2318.
  • Liner: self‑lubricating wear‑resistant material per EN 2311.
• Dimensions & tolerances:
  • Inch‑series nominal diameters use a diameter code = 1/16 inch and length code = 1/32 inch.
  • General tolerances: ISO 2768‑m (linear and angular where not otherwise specified).
• Surface treatment: Codes and options specified (examples below). Surface finishes and roughness requirements are included; dimensions relate to post‑treatment size.
  • R = Chromic or Sulphuric acid anodizing (pre‑paint)
  • S = Chromic acid anodizing (unsealed, pre‑paint)
  • T, V, M = Sealed anodizing (corrosion protection)
  • N = TSA anodizing (pre‑paint)
• Loads & performance:
  • Detailed tables for permissible radial loads (static Cs and dynamic C25) by diameter and length codes.
  • Formula note: Cs = 0,290 · d · (L − 2) based on unit pressure 290 MPa.
  • Ultimate load conditions and limiting stresses are stated (e.g., permissible bending and shear stress levels in the document).
• Marking, designation & technical data: Requirements for marking, designation format and a technical specification template are included to support procurement and interchangeability.

Practical applications

• Use in airframe fittings, hinge points, control linkages, pivot joints and other moving or fixed interfaces where lightweight, self‑lubricating bearing surfaces are needed under elevated loads.
• Common in repair, overhaul, procurement and part specification for aircraft manufacturers, MROs and suppliers.

Who should use this standard

• Aerospace part designers and structural engineers
• Component manufacturers and heat‑treatment/anodizing suppliers
• Procurement, quality and certification teams specifying bushings for aircraft systems
• Maintenance and overhaul organisations ensuring correct replacement parts

Related standards

• EN 2311 (self‑lubricating liner technical spec)
• EN 2318 (aluminium alloy specification)
• EN 2101 / EN 2284 / EN 4704 (anodizing treatments)
• ISO 2768‑1 (general tolerances)

EN 4534-2:2016 provides the authoritative dimensional, material and load data needed to specify, qualify and interchange aluminium plain bushes with self‑lubricating liners in aerospace applications.
