Technical Specification 
.webp "diagram of dsbr metric tapered roller bearings (2)")
30214 7214E 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 30214 7214E is a durable bearing ideal for axle assemblies, trailers, and agricultural machinery. Its tapered design handles axial stress smoothly.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
