Rodamientos de contacto angular de doble hilera
The contact angle α is defined as the angle between the line joining the contact points of the ball and the raceways in the radial plane, and a line perpendicular to the bearing axis.
The load carrying capacity of angular contact ball bearings increases with the increasing of contact angle. Angular contact ball bearings are generally used in pairs or even more with spacers.
