Overview

EN 4536-2:2009 - Aerospace series - Bushes, plain in corrosion resisting steel with self‑lubricating liner, elevated load - Part 2: Dimensions and loads (Inch series) specifies the dimensional, material and load characteristics for plain bushes used in aerospace fixed or moving structure and control mechanisms. The standard covers the inch‑series sizes, permissible radial loads, mass tables and mounting recommendations for bushes designed to operate between −55 °C and 163 °C.

Key topics and requirements

  • Scope & use: Plain bushes in corrosion resisting stainless steel with a self‑lubricating liner for elevated load aerospace applications (fixed and moving parts).
  • Materials:
    • Bush: stainless steel per EN 3161.
    • Liner: self‑lubricating wear‑resistant material consistent with EN 2311.
  • Temperature range: −55 °C to 163 °C.
  • Dimensions & tolerances:
    • Inch series nominal diameters encoded in 1/16 in (Table 1) and lengths encoded in 1/32 in (Table 2).
    • General tolerances per ISO 2768‑1 (m).
  • Loads:
    • Permissible static and dynamic radial loads listed in Table 3.
    • Load calculation examples given: Cs = 0.541 · d · (l − 2) and C25 = 0.259 · d · (l − 2) (d and l per code); formulas are based on unit pressures of 541 MPa and 259 MPa respectively.
  • Surface treatment:
    • Code T: passivation according to ISO 8075.
  • Design & installation:
    • Intended for interference fit installation (see figure/notes).
    • Shaft tolerance: f6 (clearance for selected shaft), housing H6.
    • Minimum shaft hardness recommendation: 50 HRC.
    • Surface finish and chamfering requirements are specified (figures).
  • Marking & designation:
    • Identification format example: EN4536-2T04005.
    • Marking rules reference EN 2424 (styles A/G based on size).

Applications and who uses it

  • Aircraft designers, structural engineers and control‑system designers select standardized bushes for pivots, bearings, linkages and control mechanisms where corrosion resistance and self‑lubrication are required.
  • Manufacturers and procurement teams use the dimensional tables, mass data and load ratings to specify components and ensure interchangeability.
  • Maintenance and overhaul organizations use the standard to verify replacement parts and correct installation (interference fit and shaft hardness/finish).
  • Keywords: EN 4536-2:2009, aerospace bushes, corrosion resisting steel, self‑lubricating liner, elevated load, inch series, dimensions and loads, interference fit.
