本标准规定了钢中球面滑动轴承的特点，具有组装槽，带或不带润滑孔和凹槽，用于飞机结构和控制机构的固定或移动部件。 它们可以在-54°C至150°C的温度范围内使用。 但是，由于使用以下润滑脂润滑（参见EN 2337）: - 酯型非常高压油脂（代码字母A），工作范围从-73°C到121°C， - 合成烃类非常高压润滑脂一般用途（代码字母B），工作范围从-54°C到177°C。 当润滑脂代号字母A润滑时，其应用领域限制在121°C

This standard specifies the characteristics of spherical plain bearings in steel, with assembly slots, with or without lubrication holes and grooves, intended for use in fixed or moving parts of aircraft structure and control mechanisms. They may be used in the temperature range from - 54 °C to 150 °C. However, as they are lubricated with the following greases (see EN 2337): - ester type very high pressure grease (code letter A), operating range from - 73 °C to 121 °C or, - synthetic hydrocarbon type very high pressure grease general purpose (code letter B), operating range from - 54 °C to 177 °C. Their field of application when lubricated with grease code letter A is limited to 121 °C.
