Product Type:Four-Row Tapered Roller Bearing

Model No.:382952X1

1. Overview

As a precision-engineered component, the 382952X1 four-row tapered roller bearing is crafted for heavy-duty machinery that demands reliability under severe loads. Its exceptional resilience makes it a cornerstone component for critical industrial equipment.

2. Basic Dimensions

Dimension Type	Value
Inner Diameter (d)	260mm
Outer Diameter (D)	370mm
Thickness (B)	256mm

3. Structural Features

The design is architected around a core set of components: two double-raceway inner rings, a single double-raceway outer ring, and two single-raceway outer rings. Inter-ring spacers are key to enabling precise clearance calibration. This synthesis results in a structurally optimized bearing capable of managing significant radial forces in conjunction with specified axial loads.

4. Load-Carrying Capacity

Radial Load Capacity: Addressing the need for higher load ratings, this bearing delivers a radial capacity 2.5-3.5 times greater than single-row tapered roller bearings, fully complying with high-precision industrial standards.
Load Type Adaptability: It provides a reliable solution for combined radial and axial load scenarios (radial-dominant), ensuring dependable performance under significant heavy and shock loading.

5. Performance Characteristics

Limiting Speed: Because of their unique structural design, especially the sliding contact between the rib and roller end face, four-row tapered roller bearings show higher friction and a relatively lower limiting speed than other same-size bearings.
Axial Load Capacity: Single-row tapered roller bearings are limited to unidirectional axial load support, but the four-row design is optimized for heavy bidirectional axial loads. It provides reliable axial positioning and efficiently manages thrust during rolling. Importantly, it primarily supports heavy radial loads for complex combined load scenarios.

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: Its application scope primarily covers work rolls and backup rolls in rolling mills.
Other Applications: Additionally, it is suitable for heavy-duty mechanical equipment such as cranes, mining machinery, and wind turbines, which necessitate high load-bearing and impact-load resistance.
