30310 7310E Metric Tapered Roller Bearings

30310 7310E 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 30310 7310E bearing is designed to support heavy combined loads with excellent durability. Made from premium steel and heat-treated for long life, it is suitable for automotive gearboxes, trailers, and heavy industrial equipment.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
