What is BS EN 4041 - Rigid single row ball bearings for aerospace applications about?
BS EN 4041 is a European Standard series that discusses components used in the aerospace industry. The purpose of BS EN 4041 is to provide the best industry design requirements for rigid single row ball bearings to ensure strength, corrosion resistance and high load-carrying capacity.
BS EN 4041 specifies the characteristics of rigid single row ball bearings in corrosion resisting steel with an extended inner ring and a solid or lightweight flanged alignment bush, designed to withstand only slow rotations and slight oscillations under load.
Rigid single row ball bearings in BS EN 4041 are intended for use in airframe fixed and moving elements and in-flight control linkages.
The bearings defined in BS EN 4041 shall be used in the temperature range from – 54 °C to 150 °C.
However, as they are lubricated with the following greases (see EN 3727):
- Ester type very high-pressure grease (Code A) and operating range from – 73 °C to 121 °C
- Synthetic hydrocarbons type very high-pressure grease general purpose and operating range from – 54 °C to 177 °C
Their field of application when lubricated with code letter A grease is limited to 121 °C.
Who is BS EN 4041 - Rigid single row ball bearings for aerospace applications for?
BS EN 4041 on rigid single row ball bearings for aerospace applications is useful for:
- Manufacturers and suppliers of rigid single row ball bearings
- Manufacturers of aerospace equipment and components
- Dealers and importers of rigid single row ball bearings
- Quality assurance services
- Product design engineers
- Aeronautical engineers
- Regulatory bodies
Why should you use BS EN 4041 - Rigid single row ball bearings for aerospace applications?
The majority of ball bearings have a single row of bearing balls. Aircraft bearings are often utilised to carry heavy loads that spin at medium to low RPMs and are frequently oscillating, due to their light weight construction and ability to withstand harsh environments.
BS EN 4041 provides you guidance on the configuration, dimensions, tolerances, clearances, torques and masses for different code numbers relating to rigid single row ball bearings, enabling you to standardize the dimensional and physical properties of rigid single row ball bearings.
BS EN 4041 guides you through dimensions and tolerances requirements, along with reference standards for materials and surface treatment, and designation requirements for rigid single row ball bearings used in the aerospace industry.
If you are a manufacturer of rigid single row ball bearings used in the aerospace industry, compliance with these requirements can ensure your products meet the performance needs of the end application.
BS EN 4041 creates a standardized approach for manufacturers of rigid single row ball bearings to adhere to if they supply their components for use by the aerospace and defence industry.
By adopting BS EN 4041, you can demonstrate stable operability, performance and longevity of rigid single row ball bearings and build trust in their use throughout the aerospace value chain.
