scope:

This standard specifies the required characteristics, inspections and tests, qualification, acceptance and delivery conditions for bearings with self lubricating liners, designed to be subjected under load to slow rotations and oscillations only. These bearings are intended to be used between fixed and moving components of the aitcraft structure, such as control surfaces, flaps, doors etc. and their control mechanisms. They are designed to be used in the temperature range of -55°C to +150°C. The requirements of this standard may also be applied to other bearings, not listed in clause 3, provided that they are conditions of procurement of such bearings.
