30307 7307E Metric Tapered Roller Bearings

30307 7307E 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 30307 7307E tapered roller bearing is ideal for medium-load applications like vehicle hubs, agricultural machinery, and transmissions. It features hardened steel construction, smooth rotation, and long-lasting lubrication retention.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
