ABSTRACT:
A spherical bearing comprising an outer member having a hole extending from side to side, at least two bearing inserts abutting the surface of the hole, the outer surface of said inserts being concave and spherical so that they provide constricted portions at each side of the outer member, the outer member also having a keyway extending axially from side to side; a key in the keyway substantially co-extensive with the keyway, the key also having a concave and spherical top surface corresponding to the outer surfaces of the hole so that the key has shoulder portions corresponding to the constricted portions of the outer member; and a partially spherical inner member, the inner member being held in the outer member by impingement of the spherical surface of the inner member against the constricted portions of the outer member and the key being held in the outer member by impingement of the shoulder portions of the key against the spherical surface of the inner member, the inserts being held in the outer member by the spherical surface of the inner member and by the key.
