Tapered Roller Bearings
Double-Row. Type SR
Double-row. type SR tapered roller bearings are widely used in applications where radial and axial loads need to be supported, such as in wheel hubs, gearboxes, and differentials of automotive vehicles, as well as in various industrial machinery.
The dimensions of these bearings are specified in millimeters, and they are designed to meet international standards for interchangeability. The designation of metric tapered roller bearings typically includes the bore diameter, outer diameter, and width.
