ANGULAR CONTACT BALL BEARINGS ANGULAR CONTACT BALL BEARINGS DOUBLE-ROW ANGULAR CONTACT Bore Diameter 10- 85mm 100 BALL BEARINGS FOUR-POINT CONTACT BALL BEARINGS DESIGN, TYPES, AND FEATURES SINGLE-ROW ANGULAR CONTACT BALL BEARINGS Since these bearings have a contact angle, they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component Is produced; therefore, two opposed bearings or a combination of more than two must be used. Since the rigidity of single-row angular contact ball bearings...
