SIST EN 3283:2001

• Abstract:

  This standard specifies the characteristics of rigid single row bearings in corrosion resisting steel of diameter series 8 and 8 designed to withstand only slow rotations and oscillations under load. They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. The airframe rolling bearings defined in this standard are used from -54°C to +150°C.

SIST EN 3283:2001 is the Slovenian standard identical to EN 3283:1994 for aerospace airframe rolling bearings. It specifies rigid single row ball bearings in corrosion resisting steel, in diameter series 8 and 9, for use in aircraft structure and control mechanisms. The standard gives the dimensions and loads for bearings intended for slow rotations and oscillations under load, in service from -54 °C to +150 °C.

What does SIST EN 3283:2001 specify?

SIST EN 3283:2001 specifies a particular family of airframe rolling bearings for aerospace use. It covers rigid single row ball bearings made of corrosion resisting steel and identifies them by diameter series 8 and 9.

The scope limits these bearings to service between fixed and moving parts of the aircraft structure and their control mechanisms. In practice, that tells designers and buyers that the document is about structural and control-system bearing applications, not general-purpose rotating machinery.

The standard is centered on the product data needed to identify and select these bearings - especially dimensions and loads. That makes it useful when comparing supplier offers, defining part numbers, or checking whether a bearing matches the required airframe application.

What are the key requirements of SIST EN 3283:2001?

The main technical points are the bearing type, the material, the series covered, the permitted motion, the application area and the operating temperature range.

• Rigid single row ball bearings - The standard applies to bearings with one row of balls and a rigid arrangement. In practice, users should select this type only where that construction matches the load path and mounting conditions.
• Corrosion resisting steel - The bearings are specified in a steel suitable for corrosion resistance. This matters in aircraft service because material choice affects durability and suitability for exposed or demanding environments.
• Diameter series 8 and 9 - The standard covers these two diameter series. Engineers and buyers need this to match the required size range and ensure interchangeability with the intended design.
• Slow rotations and oscillations under load - The bearings are intended for slow turning and back-and-forth movement while carrying load. That means they are not specified here for high-speed rotary applications.
• Aircraft structure and control mechanisms - The bearings are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. This is the key application context for design and procurement decisions.
• Operating temperature from -54 °C to +150 °C - The standard states the service temperature range for these airframe rolling bearings. Users should check that the installation environment stays within that range.

What terms does SIST EN 3283:2001 define?

The title and scope use a few core terms that frame the whole document.

• Airframe rolling bearings - Rolling bearings intended for aircraft structural applications.
• Rigid single row ball bearings - Ball bearings with one row of balls and a rigid form suited to the defined airframe use.
• Corrosion resisting steel - Steel chosen to resist corrosion in service.
• Diameter series 8 and 9 - The bearing size series covered by this standard.
• Slow rotations and oscillations under load - Operating motion limited to slow rotation or back-and-forth movement while carrying load.
• Control mechanisms - Aircraft control assemblies where the bearings are used between moving and fixed parts.

Who uses SIST EN 3283:2001?

SIST EN 3283:2001 is used by aerospace designers, airframe engineers, suppliers and buyers who need a standard bearing definition for aircraft structure and control mechanisms. It is also useful for quality and technical review when checking that a bearing offer matches the required material, series, dimensions, load data and temperature range.

In practice, users apply it when selecting bearings for a design, specifying parts for procurement, or verifying that a supplied bearing fits the intended airframe function.

What changed in SIST EN 3283:2001 from the previous edition?

SIST EN 3283:2001 is identical to EN 3283:1994.

What does the SIST EN 3283:2001 document contain?

SIST EN 3283:2001 contains the product definition for rigid single row ball bearings in corrosion resisting steel and the dimensional and load information attached to that definition. Its content is aimed at specifying the bearings for aerospace use rather than describing a general bearing theory.

The document also ties the bearings to their intended service conditions, including slow rotations, oscillations under load and the stated temperature range. That makes it a reference for design work, part selection, supplier specification and technical checking in aircraft structural and control applications.
