EN 2064:1992

Overview

EN 2064:1992 - Aerospace series - Bearings, spherical plain in corrosion resisting steel with self-lubricating liner - Technical specification (adopted nationally as SIST EN 2064:2001) defines the technical requirements for spherical plain bearings intended for aerospace applications. The standard sets out the required characteristics, inspections and tests, qualification, acceptance and delivery conditions for bearings made of corrosion-resisting steel and fitted with self-lubricating liners, designed to operate under load with slow rotations and oscillations only.

Key topics

• Scope and applicability: Bearings covered are spherical plain types with corrosion-resistant steel construction and integrated self-lubricating liners, specifically for slow rotational and oscillatory loads in aerospace components.
• Required characteristics: Material selection (corrosion-resisting steel), liner type (self-lubricating), and performance expectations are defined at a high level for design conformity.
• Inspections and tests: The standard specifies inspection and testing regimes to verify conformity (materials, dimensions, functional behaviour) prior to qualification and acceptance.
• Qualification and acceptance: Procedures and criteria for qualifying bearing designs and accepting production batches are described to ensure repeatable performance in service.
• Delivery conditions: Packaging, documentation, and delivery requirements to ensure traceability and protection of aerospace bearings in transit and storage.

Applications

EN 2064 is focused on aerospace componentry where reliability, corrosion resistance and low-maintenance operation are critical. Typical practical applications include:

• Control linkages, pivot joints and articulation points in aircraft and spacecraft where only slow rotations or oscillations occur
• Landing gear components, actuator interfaces, and structural joints requiring corrosion-resistant bearings with self-lubrication
• Use by manufacturers, design engineers and maintenance organizations specifying or procuring bearings for airframe and spacecraft assemblies

Who uses this standard:

• Aerospace designers and systems engineers specifying bearing performance
• Manufacturers of spherical plain bearings and self-lubricating liners
• Quality, test and certification engineers responsible for inspection, qualification and acceptance
• Procurement and maintenance teams enforcing delivery and traceability requirements

Related standards

• EN 2064:1992 is part of the aerospace series of technical specifications; users should also consult relevant EN and ISO bearing and material standards for complementary information on general bearing dimensions, material grades and test methods.
• National adoptions (e.g., SIST EN 2064:2001) may include local implementation details - always verify the currently applicable version for regulatory and procurement use.
