3000 series

The 3000 series is a classic universal version of lightweight tapered roller bearings, belonging to the metric single row tapered roller bearing system. It focuses on compact structure, radial+unidirectional axial composite bearing, high rigidity, and accuracy of ordinary level (P0). It is suitable for general industrial scenarios with light to medium loads and unidirectional axial positioning. It is a cost-effective support choice for automotive wheel hubs, agricultural machinery, reducers, conveying equipment and other shaft systems, and is also the basic model for adapting to small shaft diameters in tapered roller bearings.
