Features :

Product Type: Four-Row Tapered Roller Bearing

Model No.: 382060

1. Overview

A high-performance component through and through, the 382060 four-row tapered roller bearing is purpose-built for heavy-duty machinery. It excels at bearing heavy loads and impact loads, a trait that makes it indispensable for key industrial equipment.

2. Basic Dimensions

Dimension Type	Value
Inner Diameter (d)	300mm
Outer Diameter (D)	460mm
Thickness (B)	390mm

3. Structural Features

Component Composition: The assembly includes two inner rings each featuring double raceways, one outer ring with a double raceway, and two outer rings each equipped with a single raceway.
Clearance Adjustment: Dedicated spacers are arranged between the inner and outer rings to achieve precise tuning of the bearing clearance.
Load-Bearing Advantage: Through targeted structural optimization, the product can simultaneously carry large radial loads and a defined range of axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: Compared with single-row tapered roller bearings, the radial load capacity is enhanced by approximately 2.5–3.5 times, ensuring reliable performance under high-load conditions.
Load Type Adaptability: Combined radial and axial loads (with radial loads as the main force) are handled effectively, and heavy loads and impact loads in harsh working environments can be withstood.

5. Performance Characteristics

Limiting Speed: Somewhat lower than four-row cylindrical roller bearings due to structure, but ideal for heavy-load operations.
Axial Load Capacity: Bears axial loads from both sides, working effectively as a bidirectional thrust bearing in harsh industrial settings.

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: Designed for rolling mill work/backup rolls → matches European rolling mills’ high-precision + heavy-load needs.
Other Applications: Widely used in heavy-duty equipment (cranes, mining machinery, wind turbines) requiring excellent high-load/impact load resistance.
