This part of IS0 10792 specifies the characteristics of
spherical plain bearings in corrosion-resisting steel
with self-lubricating liner, narrow and wide series, for
elevated loads at ambient temperature, for use in
fixed or moving parts of the aircraft structure and
control mechanisms at temperatures of -55 “C to
+I63 “C.
It is applicable to self-lubricating spherical plain
bearings (without rolling elements) consisting of an
outer ring having a concave sphered sliding contact
surface with self-lubricating liner and inner ring having
a matched convex sphered sliding contact surface.
At the time that this part of IS0 10792 was
developed, airframe spherical plain bearings with
dimensions originally specified in Imperial units were
dominant in world application. For this part of
IS0 10792, the dimensions of these bearings have
been converted into metric units with the original
characteristics given in annex A for information only.
For new applications, the use of the bearings
specified in IS0 10792-l is recommended.
