BS EN 4156 is a European Standard that discusses components used in the aerospace industry. The purpose of BS EN 4156 is to provide the best industry design requirements for rod ends such that they are fit for the intended end-application use.
BS EN 4156 specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing and threaded shank in steel, inner ring and balls in corrosion resisting steel.
They consist of:
These rod ends are intended for use with flight control rods or rods for aerospace structures.
They are intended to be used in the temperature range: – 54 °C to 150 °C.
However, being lubricated with the following greases:
Their field of the application when lubricated with codes A and C grease is limited to 121 °C.
BS EN 4156 on adjustable rod ends for use in the aerospace industry is useful for:
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance and durability are crucial.
BS EN 4156 assists you with the dimensions, tolerances and surface roughness requirements, and guides you through materials requirements and surface treatment procedures for adjustable rod ends.
If you are a manufacturer of adjustable rod ends used in the aerospace industry, compliance with these requirements can ensure your products meet the performance needs of the end-application.
With compliance to the best industry recommendations specified in BS EN 4156, you can demonstrate the reliability of adjustable rod ends and build trust in their use throughout the aerospace supply chain.
