Abstract
In a sewing machine, an oscillating cradle has two bearings in which a needle bar is slidingly mounted. An external surface of each bearing has a spherical profile by which it is pivotingly engaged in a respective seat of complementary shape provided in a first arm of the cradle, for an upper bearing, and in a second arm, for a lower bearing. A resilient leaf spring, in the form of a U, exerts an axial pressure on both the upper bearing and the lower bearing, to maintain them in their seats in alignment with one another.
