30313 7313E Metric Tapered Roller Bearings

30313 7313E single row tapered roller bearings are engineered to support combined radial and thrust loads with minimal rolling resistance. The inner assembly—comprising the raceway, rollers, and cage—is separable from the outer ring, allowing for flexible installation, simplified disassembly, and easy maintenance. When used in matched pairs with preload, these bearings deliver high rigidity and precise shaft positioning. 

The 30313 7313E bearing features optimized load distribution and low friction. Widely used in commercial vehicles, it ensures smooth operation in hub assemblies and high-load rotating components.Ideal for heavy-duty applications, they offer:

• Excellent capacity for both radial and axial forces

• Support for axial loads in a single direction

• Reduced friction for efficient, high-speed operation

• Durable, replaceable, and service-friendly design
