What is BS EN 4156 – Adjustable rod ends for use in the aerospace industry about?
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:
- A rod end comprising
- either seals or shields
- An optional longitudinal groove for locking purpose
- An inner ring with balls.
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:
- Very high pressure grease, ester type (code A), operational range – 73 °C to 121 °C according to MIL-PRF-23827 type II
- Very high-pressure grease, synthetic hydrocarbons, general-purpose (code B), operational range − 54 °C to 177 °C (see EN 2067), according to MIL-PRF-81322.
- Very high-pressure grease, lithium type (code C) operational range – 73 °C to 121 °C according to MIL-PRF-23827 type I.
Their field of the application when lubricated with codes A and C grease is limited to 121 °C.
