Technical Specification 
.webp "diagram of dsbr metric tapered roller bearings (2)")
The 33109 3007709E tapered roller bearing is designed for applications requiring reliable handling of both radial and axial loads. With precision-matched inner and outer rings and optimized roller geometry, it ensures stable rotation and long service life under heavy-duty conditions. Commonly used in automotive hubs, industrial gearboxes, and agricultural equipment, 33109 bearings from DSBR are produced with strict quality standards and excellent surface finishing to reduce friction and noise.
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
