SIST EN 2079:2001 is a Slovenian standard from SIST for aerospace bearings. It specifies the required dimensions and loads for precision ball bearings in corrosion resisting steel, with flange, for instruments and aircraft equipment. In practice, it helps designers, buyers, and quality teams identify the bearing type they need and check that the part matches the intended aerospace application.

What does SIST EN 2079:2001 specify?

SIST EN 2079:2001 specifies the required characteristics for precision ball bearings in corrosion resisting steel for instruments and aircraft equipment. The scope is focused on bearings that are with flange, with radial contact, with deep groove, and without filling slot.

For a reader, that means the standard is aimed at a specific bearing design rather than general-purpose bearings. It is used when the application needs controlled dimensions and load data for aerospace instrument and equipment assemblies.

What are the key requirements of SIST EN 2079:2001?

SIST EN 2079:2001 is a dimensional and load standard. Its main purpose is to define the bearing characteristics that matter when selecting, designing, or checking a part for use in instruments and aircraft equipment.

Bearing type and construction

SIST EN 2079:2001 applies to precision ball bearings made in corrosion resisting steel and having a flange, radial contact, and a deep groove, without a filling slot. This tells the reader exactly which bearing construction is covered, so the standard should be matched only to that configuration.

Dimensions

SIST EN 2079:2001 covers the dimensions of the bearing type it names in the title. In practice, this is what manufacturers and purchasers use to verify interchangeability, fit, and mounting compatibility in equipment design.

Loads

SIST EN 2079:2001 also specifies loads for these bearings. For engineers, the load information is the basis for checking whether the bearing can support the intended service conditions in instruments and aircraft equipment.

Aerospace use

SIST EN 2079:2001 is written for the aerospace field, specifically instruments and aircraft equipment. That matters because users need parts that can be selected and verified against the dimensional and load characteristics expected in aerospace assemblies.

What terms does SIST EN 2079:2001 define?

The available document information does not show a separate definitions clause. The key terms used in the standard title and scope are:

• Precision ball bearing - a ball bearing intended for accurate and controlled use where dimensions and performance matter.
• Corrosion resisting steel - steel chosen to better resist corrosion in service.
• Flange - a projecting rim used for location or mounting.
• Radial contact - a bearing arrangement intended to carry radial load.
• Deep groove - a groove profile associated with ball bearing geometry.
• Filling slot - an opening in some bearings; this standard applies to bearings without one.

Who uses SIST EN 2079:2001?

SIST EN 2079:2001 is used by aerospace designers, bearing manufacturers, procurement teams, and quality personnel working on instruments and aircraft equipment. Designers use it to choose the bearing type and geometry; buyers use it to specify the part correctly; quality teams use it to check conformance to the required dimensions and loads.

What changed in SIST EN 2079:2001 from the previous edition?

SIST EN 2079:2001 is identified as identical to EN 2079:1995. The document information provided here states that relationship and does not describe any further changes.

What does the SIST EN 2079:2001 document contain?

SIST EN 2079:2001 contains the specification for the bearing type named in the title, with its dimensions and load-related information. It is a technical reference for selecting and checking precision ball bearings in corrosion resisting steel with flange for instruments and aircraft equipment.

The document is intended for design, procurement, and verification work. Its content supports matching the bearing geometry to the application and using the load data when checking suitability for service.
