Abstract
A roller bearing of very small axial extension and with sliding annular elastic seals is provided for forming a connection joint. Opposing shoulder rings project orthogonally beyond the guide and rolling track of the bearing outer race, which race is of rectangular cross-section. The rings are held in position by the two cheeks of the female part of the joint that is to be formed. Annular elastic seals, moreover, cooperate under axial action with the sides of the bearing outer race. Preferred embodiments of the seals and of the shoulder rings are also provided.
