Product Type: Four-Row Tapered Roller Bearing

Model No.: 380672-2

1. Overview

Exclusively designed for heavy-duty machinery, the 380672-2 four-row tapered roller bearing is high-performance, resists heavy and impact loads well, and is perfect for critical industrial equipment.

2. Basic Dimensions

Dimension Type	Value
Inner Diameter (d)	360mm
Outer Diameter (D)	510mm
Thickness (B)	380mm

3. Structural Features

Component Composition: The proposed component comprises two double-raceway inner rings, one double-raceway outer ring, and two single-raceway outer rings.
Clearance Adjustment: Precise clearance tuning will be achieved via spacers between inner and outer rings, ensuring project compatibility.
Load-Bearing Advantage: Structural optimization enables simultaneous bearing of large radial loads and certain axial loads, supporting project performance requirements.

4. Load-Carrying Capacity

Radial Load Capacity: Its radial load capacity is about 2.5–3.5 times stronger than single-row tapered roller bearings, so you can count on reliable performance even under high-load conditions.
Load Type Adaptability: It works well with combined radial-axial loads (radial is the main force) and can handle heavy loads and impact loads in harsh working environments—perfect for your equipment needs.

5. Performance Characteristics

Limiting Speed: Experimental observations show that the limiting speed is moderately lower than that of four-row cylindrical roller bearings, which is attributed to its structural design. Nevertheless, it is fully suitable for heavy-load operating conditions.
Axial Load Capacity: The component demonstrates the capability to bear axial loads from both directions and exhibits reliable performance as a bidirectional thrust bearing in harsh industrial environments.

6. Material & Manufacturing

Component	Material
Inner & Outer Rings	Carburized Steel
Rolling Elements	Bearing Steel
Cage	Stamped Steel Plate

Heat Treatment: Special heat treatment process applied to enhance hardness, wear resistance, and fatigue life.

7. Application Fields

Primary Application: The product is specifically designed for the work rolls and backup rolls of rolling mill systems, and it has been verified to perfectly match the high-precision and heavy-load requirements of European-standard rolling mill equipment.
Other Applications: Experimental data shows it is widely applicable to heavy-duty mechanical equipment, including cranes, mining machinery, and wind turbines, all of which have stringent demands for resistance to high loads and impact loads.
