Abstract
A rod end bearing comprising a body comprising a ring portion and a rod portion. The ring portion comprises a ring having an opening, the opening having a center axis. The rod portion comprises a first rod extending radially from the ring in a direction perpendicular to the center axis. The opening having a geometry sufficient to support a substantially spherical ball bearing, and permit rotation of the ball bearing inside the ring. The inner periphery of the ring is in contact with the ball bearing and includes a wear coating. An antifriction coating is disposed on a surface selected from the group consisting of a surface of the wear coating, a surface of the ball bearing and combinations thereof. The antifriction coating maintains a coefficient of friction between the wear coating and the ball bearing of up to about 0.95 in atmospheres substantially devoid of water vapor.
