Features :

Product Type:Four-Row Tapered Roller Bearing

Model No.:382040

1. Overview

The 382040 four-row tapered roller bearing is a high-performance component dedicated to heavy-duty machinery. With its extraordinary capacity to bear heavy and impact loads, it serves as a perfect choice for essential industrial equipment.

2. Basic Dimensions

Dimension Type	Value
Inner Diameter (d)	200mm
Outer Diameter (D)	310mm
Thickness (B)	275mm

3. Structural Features

Component Composition: The assembly consists of two inner rings, each with a double raceway, one double-raceway outer ring, and two additional outer rings with single raceways.
Clearance Adjustment: Precise clearance adjustment is achieved through the use of spacers positioned between the inner and outer rings.
Load-Bearing Advantage: Its design is optimized to handle large radial loads concurrently with a degree of axial loading.

4. Load-Carrying Capacity

Radial Load Capacity: The radial load it can bear is around 2.5-3.5 times that of single-row tapered roller bearings, fully meeting the high-precision load needs of industrial equipment.
Load Type Adaptability: It is specially crafted to accommodate combined radial and axial loads (with radial loads as the primary component), and possesses excellent ability to resist heavy loads and impact loads.

5. Performance Characteristics

Speed Limitation: The design of this bearing prioritizes load capacity over speed. As a result, its maximum speed is lower than that of four-row cylindrical roller bearings, a direct consequence of its structural configuration.
Bidirectional Axial Capacity: This bearing can withstand axial forces in both directions, making it an effective bidirectional thrust bearing solution for applications with reversing axial loads.

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 primary application for this product is in the work and backup rolls of rolling mills, where its attributes are precisely aligned with the high-precision, heavy-load specifications of European equipment.
Other Applications: Its versatility extends to other realms of heavy-duty machinery, such as cranes, mining equipment, and wind turbines, applications that critically depend on excellent load and impact resistance.
