Overview

SIST EN 2585:2019 is a European standard developed for the aerospace industry, specifying the characteristics and requirements of spherical plain bearings made of corrosion-resistant steel and featuring a self-lubricating liner. These bearings are part of the wide series designed for elevated load applications at ambient temperatures, making them suitable for both fixed and moving parts within aircraft structures and control mechanisms. This standard defines the dimensions, permissible loads, surface treatments, marking, and quality management specifics necessary to ensure reliable and consistent performance in demanding aerospace environments. The bearings covered by this standard are intended for operational temperature ranges from -55°C to +163°C.

Key Topics

• Product Scope: Spherical plain bearings in corrosion-resistant steel with a self-lubricating liner, wide series, capable of handling high static and dynamic loads at ambient temperatures.
• Configuration: Includes variants with or without a swaging groove for specific installation or application requirements.
• Material Requirements: Inner and outer rings are manufactured from corrosion-resistant steels compliant with relevant aerospace steel standards, ensuring durability and longevity.
• Surface Treatments: Specifies allowable treatments such as chromium plating and passivation to enhance corrosion resistance and wear performance.
• Dimensions and Tolerances: Provides precise guidance on dimensions and tolerances crucial for interoperability and fitment in aircraft assemblies.
• Permissible Loads: Defines static and dynamic radial and axial load capacities ensuring suitability for high-demand aerospace applications.
• Quality Management: Mandates implementation of a recognized quality management system (such as EN 9100) for production, promoting product consistency and traceability.
• Marking and Traceability: Details the requirements for component marking, ensuring traceability and compliance within aerospace supply chains.

Applications

SIST EN 2585:2019 bearings are specifically intended for critical aerospace applications, including:

• Aircraft Structures: Employed in both fixed and moving assemblies to support either static or dynamic loads with reduced maintenance due to the self-lubricating liner.
• Control Mechanisms: Suitable for flight controls, landing gears, and other movement-critical subsystems, where reliability, minimal friction, and longevity are essential.
• Other Aerospace Systems: Adaptable for use in satellites, spacecraft, and advanced aviation systems exposed to challenging operational environments and varying temperatures.

These spherical plain bearings offer essential benefits such as corrosion resistance, reduced maintenance, and long service life, making them a preferred choice for designers and engineers focused on performance and safety compliance in aerospace engineering.
