Features :

Product Type:Four-Row Tapered Roller Bearing

Model No.:382034X2

1. Overview

The 382034X2 four-row tapered roller bearing is a high-performance component tailored specifically for heavy-duty machinery. Boasting exceptional capacity to withstand heavy and impact loads, it serves as an ideal option for critical equipment in industrial sectors.

2. Basic Dimensions

Dimension Type	Value
Inner Diameter (d)	170mm
Outer Diameter (D)	260mm
Thickness (B)	230mm

3. Structural Features

Component Composition: Comprises two double-raceway inner rings, one double-raceway outer ring, and two single-raceway outer rings.
Clearance Adjustment: Spacers are installed between the inner and outer rings to enable precise clearance adjustment.
Load-Bearing Advantage: Structurally optimized to simultaneously withstand large radial loads and certain axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: Radial load capacity is about 2.5-3.5 times stronger than single-row tapered roller bearings, ensuring reliable performance under high-load conditions.
Load Type Adaptability: Works well with combined radial and axial loads (radial loads being the main force) and can stand up to heavy loads and impact loads in harsh working environments.

5. Performance Characteristics

Limiting Speed: The limiting speed is somewhat lower than four-row cylindrical roller bearings due to structural design, but it’s fully suitable for heavy-load operating scenarios.
Axial Load Capacity: Can bear axial loads from both sides and works well 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: Mainly used in work rolls and backup rolls of rolling mills, fully adapting to the harsh operating conditions of local rolling industry.
Other Applications: Suitable for various heavy-duty mechanical equipment such as cranes, mining machinery, and wind turbines, capable of withstanding high loads and impact loads in complex working environments.
