3. Structural Features

Component Composition: Its design features two inner rings with double raceways, one double-raceway outer ring, and two single-raceway outer rings.
Clearance Adjustment: Clearance adjustment is facilitated by spacers located between the inner and outer rings.
Load-Bearing Advantage: The structural configuration is engineered to simultaneously support high radial loads and moderate axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: The radial load-bearing performance reaches approximately 2.5-3.5 times that of single-row tapered roller bearings, satisfying the high-precision industrial load criteria.
Load Type Adaptability: It is specifically engineered to bear combined radial and axial loads (with radial loads as the main component), and shows great resistance to heavy loads and impact loads.

5. Performance Characteristics

Limiting Speed: Structurally limited speed; lower than four-row cylindrical rollers but offers higher load capacity.
Axial Load Capacity: Accepts axial loads in both directions; can function as a bidirectional thrust bearing.
