30222 7222E Metric Tapered Roller Bearings

30222 7222E 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 30222 7222E bearing offers exceptional performance in high-impact systems. Perfect for gearboxes and large-scale axles.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
