Overview
SIST EN 3284:2001 is a European standard published by CEN that defines the specifications for rigid single row ball bearings in steel, specifically for aerospace applications. It focuses on bearings within diameter series 0 and 2, categorized under normal clearance. These bearings are engineered to withstand slow rotations and oscillations under load, making them ideal for use in aircraft airframe rolling mechanisms and control components. The standard ensures these components operate reliably across a broad temperature range from -54°C to +150°C.
Key Topics
- Bearing Type: Rigid single row ball bearings made of steel
- Diameter Series: Series 0 and Series 2 bearings covered
- Clearance Category: Normal clearance classification
- Load and Dimension Specifications: Exact parameters for dimensions and load capacities
- Operational Conditions: Suitable for slow rotational or oscillatory motion under load
- Temperature Range: Performance guaranteed between -54°C and +150°C
- Applications in Aerospace: Designed specifically for airframe rolling components, including fixed and moving parts of aircraft structure and control systems
Applications
SIST EN 3284:2001 bearings are predominantly applied in aerospace industry components where precise, robust, and durable bearings are crucial. Typical applications include:
- Aircraft landing gear mechanisms requiring reliable slow movement
- Flight control linkages where oscillation and slow rotation bearings are essential
- Mechanical joints in airframe structures subject to oscillating loads
- Bearings between fixed and moving aircraft structural parts where operational reliability at extreme temperatures is mandatory
These bearings contribute to enhanced safety, mechanical performance, and longevity of aerospace components exposed to varying environmental conditions.
