Inner half ring for spherical sliding bearing

The inner semi-ring (6, 8) for a spherical sliding bearing comprises a spherical outer surface (10), an inner surface having a rotating cylinder about an axis comprising a center of the outer surface (10), first and second flat front faces defining the semi-ring (6, 8) in a circumferential direction, the first and second front faces extending between the outer surface and the inner surface. The semi-rings (6, 8) comprise a first central groove (24) on the first front face, the first central groove (24) extending between the outer surface (10) and the inner surface. 该用于球面滑动轴承的内半环(6、8)包括球面外表面(10)、具有围绕包括外表面(10)的中心的轴线旋转圆柱体的内表面、在周向方向上界定半环(6、8)的第一和第二平坦正面，该第一和第二正面在外表面和内表面之间延伸。该半环(6、8)包括在第一正面上的第一中心凹槽(24)，第一中心凹槽(24)在外表面(10)和内表面之间延伸。
