.webp "diagram of dsbr metric tapered roller bearings (2)")
DSBR's 33120 3007720 tapered roller bearing offers exceptional load-handling capabilities, high-speed stability, and long lifespan. Crafted from high-purity bearing steel and inspected with strict quality controls, this bearing performs reliably in large powertrain systems and heavy-duty drive assemblies. Its optimized geometry reduces wear and supports extended lubrication intervals.
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
