3. Structural Features

Component Composition: Two double-raceway inner rings, plus one double-raceway outer ring and two single-raceway outer rings.
Clearance Adjustment: Spacers between inner/outer rings enable precise clearance tuning.
Load-Bearing Advantage: Structural optimization allows simultaneous bearing of large radial loads and specific axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: Not only does it meet high-precision standards, but its radial load capacity also significantly surpasses that of single-row tapered roller bearings by a factor of 2.5 to 3.5.
Load Type Adaptability: Designed for the challenges of predominantly radial combined loads, it additionally provides exceptional resistance to heavy and high-impact forces.

5. Performance Characteristics

Limiting Speed: Notwithstanding a 15-20% reduction in maximum rotational velocity compared to four-row cylindrical roller bearings, the structural configuration remains commensurate with all heavy-load operational requirements.
Axial Load Capacity: Engineered for omnidirectional axial load absorption, this bearing sustains thrust bearing functionality in industrially challenging applications.
