This European standard specifies the characteristics of inch based spherical plain bearing, metal to
metal, in corrosion resisting steel, narrow series.
They are intended for use in fixed or moving parts of the aircraft structure and their control
mechanisms.
They shall be used in the temperature range as determined by the grease capability as below:
— code A: grease as per MIL-PRF-23827 Type I, operating temperature range −73 °C to 121 °C;
— code B: grease as per MIL-PRF-81322, operating temperature range −54 °C to 177 °C.
The range of application for bearings lubricated with grease per code A is limited to 121 °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).

This document is to be used together with EN 13001-1 and EN 13001-2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of cranes by design and theoretical verification.
NOTE 1 Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type.
This document covers bearings in cranes. It is not intended for bearings being part of standard components, e.g. gearboxes, motors - however those bearings shall be designed using load actions from EN 13001-2 and classification parameters of EN 13001-1.
NOTE 2 EN 13001-3-7 is under preparation for gears and gearboxes and deals with load actions for bearings in gear boxes.
The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 4 to 7 of this document are necessary to reduce or eliminate risks associated with the following hazards:
- exceeding the limits of strength (yield, ultimate, fatigue);
- exceeding temperature limits of material or components;
- elastic instability of the crane or its parts (buckling, bulging).
This document is not applicable to cranes which are manufactured before the date of its publication as an EN and serves as reference base for the European Standards for particular crane types (see Annex D).
NOTE EN 13001-3-4 deals only with limit state method in accordance with EN 13001-1.

ISO 21107:2015 establishes a search structure and properties vocabulary for identifying rolling bearings, bearing housings, accessories and spherical plain bearings primarily with the aid of electronic media, such as the Internet. The methodology for using this International Standard in search programs is not included. ISO 21107:2015 does not establish a search structure and an attribute vocabulary for identifying linear motion rolling bearings. NOTE A reference dictionary for all rolling bearings in this document is defined in ISO/TS 23768‑1. It contains definitions of bearing classes, data element types of descriptive properties and domains of values.

1.1 This part of ISO 683 specifies the technical delivery requirements for five groups of wrought ball
and roller bearing steels as listed in Table 3, namely
— through-hardening bearing steels (steels with about 1 % C and 1 % to 2 % Cr),
— case-hardening bearing steels,
— induction-hardening bearing steels (unalloyed and alloyed),
— stainless bearing steels, and
— high-temperature bearing steels.
1.2 This part of ISO 683 applies to the products and heat-treatment conditions given in Table 1 and the
surface conditions given in Table 2.
1.3 In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are
applicable.
