Cuscinetto obliquo a sfere SKF 3203 A-2ZTN9/MT33, Diametro esterno: 40 mm | Diametro interno: 17 mm | Larghezza: 17.5 mm

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

I cuscinetti obliqui a due corone di sfere con tenute su ambo i lati corrispondono a una coppia di cuscinetti obliqui a una corona di sfere in disposizione ad "O", ma richiedono meno spazio assiale. In base alla variate della tenuta, possono operare a velocità elevate e sono più idonei dei cuscinetti radiali a sfere per compensare forze assiali di grande entità in ambo le direzioni.
