Overview
EN 3383:2012 is a European aerospace standard that specifies the characteristics of internal, axial-mounting retaining rings made of steel with vacuum cadmium plating. Intended for aerospace applications, the standard defines configuration, dimensional data (diameter codes), material hardness, surface treatment requirements and designation/marking rules. Note: the cadmium plating limits service temperature to not exceeding 235 °C.
Key Topics and Requirements
- Scope: Axial mounting internal retaining rings for aerospace use (steel, vacuum cadmium plated).
- Materials / Hardness: Spring steel with specified hardness:
- Diameter codes 008–038: 480–530 HV
- Diameter codes 040–165: 440–510 HV
- Surface treatment: Vacuum cadmium plating per EN 2535. Where contact conditions apply, a deposit thickness of 5 µm to 9 µm is required on surfaces that can be contacted by a 20 mm ball; other surfaces must have a continuous deposit.
- Dimensions and mass: The standard provides detailed dimensional tables and tolerances (diameter codes, A/B/P/S/R, D1–D4, tolerances h11) and approximate masses (kg/1 000 pieces). Values in tables apply after cadmium plating.
- Designation and marking: Provides a standard designation format (example: “RETAINING RING, INTERNAL, AXIAL MOUNTING - EN 3383 – 016”) and marking requirements referencing EN 2424 (style G).
- Related technical specs and mounting: References EN 3380 for technical specifications and EN 3425 for groove dimensions and mounting instructions.
- Limitations: Cadmium-plated rings are restricted by temperature and potential environmental/handling considerations associated with cadmium.
Applications and Who Uses This Standard
- Aerospace component designers specifying reliable internal axial retaining rings for shafts, bores and assemblies.
- Manufacturers and suppliers producing retaining rings to consistent dimensional, hardness and plating standards for aircraft systems and subsystems.
- Quality assurance / inspection teams verifying conformity to specified dimensions, surface deposit thickness and hardness values.
- Procurement and maintenance professionals ensuring correct part designation, marking and compatibility with groove dimensions and mounting practices.
- Typical uses include securing assemblies within aerospace bearings, housings and structural components where precise axial retention and traceable plating/marking are required.
