3. Structural Features

Component Composition: It comprises two inner rings with double raceways, one outer ring with a double raceway, and two outer rings with single raceways.
Clearance Adjustment: Spacers positioned between the inner and outer rings facilitate accurate clearance adjustment as required.
Load-Bearing Advantage: Structural optimization endows the component with the capability to concurrently withstand large radial loads and specific axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: Its radial load-bearing capacity is approximately 2.5 to 3.5 times higher than that of single-row tapered roller bearings, guaranteeing stable and reliable performance even under high-load operating conditions.
Load Type Adaptability: It demonstrates excellent performance when subjected to combined radial and axial loads (with radial loads as the main force) and is capable of withstanding heavy loads and impact loads in severe working environments.

5. Performance Characteristics

Limiting Speed: The design represents a strategic trade-off between velocity limitations and load-bearing capacity, delivering specialized performance for heavy-duty applications.
Axial Load Capacity: Incorporating multi-directional axial load capability, this engineering solution provides thrust bearing services in severe operating environments.
