30318 7318E Metric Tapered Roller Bearings

30318 7318E 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. 

Engineered for large-scale applications, the 30318/7318E tapered roller bearing provides stable rotation under demanding conditions. Used in heavy trucks, mining gear, and rotating assemblies requiring longevity and strength.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
