Abstract
A pivot bearing comprises a shaped bar having an outer circumferential surface provided with two oppositely arranged, longitudinally extending notches, and a sleeve arranged on the shaped bar and having an externally cylindrical surface and an inner circumferential surface facing the outer circumferential surface of the shaped bar and provided with two oppositely arranged longitudinally extending notches. The longitudinally extending notches of the shaped bar are in alignment with the longitudinally extending notches of the sleeve to form two pairs of notches, and cylindrical pins are arranged in the two pairs of notches.

A pivot bearing comprising
- (a) a shaped bar having an outer circumferential surface provided with two oppositely arranged, longitudinally extending notches,
- (b) a sleeve arranged on the shaped bar and having
- (1) an externally cylindrical surface and
- (2) an inner circumferential surface facing the outer circumferential surface of the shaped bar and provided with two oppositely arranged longitudinally extending notches,
- (3) the longitudinally extending notches of the shaped bar being in alignment with the longitudinally extending notches of the sleeve to form two pairs of notches, and
- (c) cylindrical pins in abutment with the faces of the notches arranged in the two pairs of notches.
A pivot bearing comprising
- (a) a shaped bar having an outer circumferential surface provided with two oppositely arranged longitudinally extending notches extending along the entire length thereof,
- (b) a sleeve arranged on the shaped bar and having
- (1) an externally cylindrical surface and
- (2) an inner circumferential surface facing the outer circumferential surface of the shaped bar and provided with two oppositely arranged longitudinally extending notches extending along the entire length thereof,
- (3) the longitudinally extending notches of the shaped bar being in alignment with the longitudinally extending notches of the sleeve to form two pairs of notches, and
- (c) cylindrical pins in abutment with the faces of the notches arranged in the two pairs of notches.
A pivot bearing comprising
- (a) a shaped bar having an axis and an outer circumferential surface provided with two oppositely arranged, longitudinally extending notches,
- (b) a sleeve arranged on the shaped bar, the sleeve being comprised of two cup halves and the cup halves being screwed together at conjugated diameters equidistantly from the axis of the shaped bar, and the sleeve having
- (1) an externally cylindrical surface and
- (2) an inner circumferential surface facing the outer circumferential surface of the shaped bar and provided with two oppositely arranged longitudinally extending notches,
- (3) the longitudinally extending notches of the shaped bar being in alignment with the longitudinally extending notches of the sleeve to form two pairs of notches, and
- (c) cylindrical pins in abutment with the faces of the notches arranged in the two pairs of notches.
