EN 6098-2019 pdf download.Aerospace series – Rod-end with bearing per EN 6097 in corrosion resisting steel, extra wide inner ring, external threaded shank – Dimensions and loads – Inch series.
This EN 6098 specifies the characteristics of adjustable rod ends consisting of:
— a spherical plain bearing, metal to metal, in corrosion resisting steel, extra wide series (EN 6097); a rod-end with threaded shank with an optional longitudinal groove for locking purposes.
They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms.

4 Requirements
4.1 Configuration, dimensions, tolerances and mass
Configuration, dimensions, tolerances and mass shall be according to Figure 1 and Table 1 and Table 2.
Table 1: Dimensions and tolerances are expressed in millimetres (inches).
Figure 1: Dimensions and tolerances for Ra max. are expressed in urn (pin).
4.5 Materials
Inner ring: See product standard EN 6097.
Outer ring: See product standard EN 6097.
Rod- end body: See AMS 5643, hardness 35 ≤ HRC ≤ 42.
4.6 Surface treatment
Rod-end body:
— code T: passivated according to ISO 8074;
— code P: cadmium plating and chromating according to EN 2133, 10 tm to 20 pm (400 pin to 800 pin);
