UNE-EN 4036:2021

This document specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing with reduced internal radial clearance and threaded shank in corrosion resisting steel, designed to withstand only slow rotations and oscillations under load.

They consist of:

a rod end comprising:

circumferential groove to identify location;

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; or

very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range "54 °C to 177 °C (see EN 2067);

their field of application when lubricated with code A grease is limited to 121 °C.
