Self-aligning Roller Bearings 81513431616
Double-row Tapered Roller Bearings are radial thrust rolling bearings with tapered rollers as the rolling elements. Their structural features include two single-row tapered roller bearings sharing the same inner and outer rings, enabling them to simultaneously withstand radial and bidirectional axial loads.
Structural Features
Double-row arrangement: Composed of two single-row tapered roller bearings, sharing the inner and outer rings, with clearance adjusted via spacer rings.
Contact angle design: The contact angle (¦Á) typically ranges from 10¡ã to 30¡ã, with a larger contact angle resulting in stronger axial load-carrying capacity.
Sealing design: Some models feature a double-sided sealing structure (e.g., bearings specifically designed for hot-rolled sheet metal rolling mills), utilizing primary and secondary lip seals along with spring mechanisms to prevent foreign object ingress and grease leakage.
Application Scenarios
Widely used in gearboxes, cranes, rolling mills, mining machinery, and other heavy-duty mechanical equipment, as well as in applications requiring bidirectional axial support, such as oil pumps and air compressors.
