30320 7320E Metric Tapered Roller Bearings

30320 7320E 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 30320 7320E bearing is suitable for oversized axle hubs and rotating shafts. Its large diameter and precision raceway design allow it to endure extreme radial and thrust loads while delivering smooth operation.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
