4 Requirements
4.1 Configuration, dimensions, tolerances and mass
Configuration, dimensions, tolerances and mass shall be according to Figure 1 and Table 1.
Table I and Table 5: Dimensions and tolerances are expressed in millimetres (inches).
Figure 1: Dimensions and tolerances for Ra max. are expressed in lim (iin).
Values apply after surface treatment.
4.2 Surface roughness
Surface roughness shall be according to Figure 1.
Surface roughness is measured before surface treatment.
4.5 Material
Inner ring: see product standard EN 4265.
Outer ring: see product standard EN 4265.
Rod-end body: see AMS 5643. hardness 35 ≤ HRC ≤ 42.
4.6 Surface treatment
Surface treatment as defined in chapter 5 (designation) with following codes:
— rod-end body:
— code T: passivated according to ISO 8074;
— code P: cadmium plating and chromating according to EN 2133k 10 tm to 20 im (400 jim to 800 pin);
— exception: threads, 5 jim to 15 pm (200 pin to 600 pin);
— bearing: see EN 4265.
4.9 Temperature range and lubricant
They shall be used in the temperature range as determined by the grease capability see below.
As they are lubricated by means of the following greases:
— code A: grease as per MIL-PRF-23827 type 1, operating temperature range —73 °C to 121 °C;
— code B: grease as per MIL-PRF-81322, operating temperature range —54 °C to 177 °C.
In both cases the spherical surface of the outer or inner ring, have to be provided with a dry-film lubricant as per MIL-PRF-46010 or equivalent (anti-seizing protection).
6 Marking
Marking shall be according to EN 2424, style A.
7 Technical specification
Technical specification shall be according to EN 6099.
8 Quality management systems
The manufacturer’s operations shall be an approved production organisation for aerospace products and shall demonstrate that it has implemented and is able to maintain a quality management system (e.g. according to EN 9100 or an equivalent aerospace accepted and established quality management system).
The qualification procedure for aerospace standard products (e.g. according to EN 9133 or an equivalent aerospace accepted and established qualification procedure) shall be used and documented according to the specified tests if not otherwise agreed between customer and supplier.BS/EN 6055-2019 pdf download.
