Describes the required characteristics, inspection and test methods, qualification and acceptance conditions for spherical plain bearings in corrosion resisting steel, self aligning with self-lubricating liner designed to withstand (under load) slight swiveling and slow rotations only.

This European Standard specifies the required characteristics, inspection and test methods, qualification and acceptance conditions for spherical plain bearings in corrosion resisting steel, self aligning with self lubricating liner designed to withstand (under load) slight swivelling and slow rotations only. This standard applies whenever referenced. These bearings prEN 4538-1, prEN 4538-2, prEN 4539-1 and prEN 4539-2 are for actuator applications and for use in the temperature range - 54 °C to 163 °C and for EN 4538-003 and EN 4539-003 for use in the temperature range - 54 °C to 120 °C. The liner may be of a fabric or composite material bonded to the inside diameter of the outer ring or in a composite material moulded into a pre-formed cavity between the inner and outer rings. The duty cycle (Annex E, normative) has been established on the basis of a civil aircraft aileron surface application.
