Tapered Roller Bearings

Description

Structure and Features
• Tapered Design: The extended lines of the inner ring, outer ring raceways, and rollers intersect at a common point, ensuring uniform load distribution.
• High Load Capacity: Capable of withstanding radial loads and single-direction axial loads; when used in pairs, can accommodate bi-directional axial loads.
• Separable Structure: The inner ring assembly (inner ring + rollers + cage) and outer ring can be separated for easy installation, adjustment, and maintenance.
• Adjustable Clearance and Preload: The clearance can be adjusted according to application requirements, improving rigidity and extending service life.

Main Series
1. Single-Row Tapered Roller Bearings
• The most common type.
• Designed to handle radial and single-direction axial loads.
• Widely used in automobile wheel hubs, gearboxes, and industrial machinery.
2. Double-Row Tapered Roller Bearings
• Essentially two single-row bearings combined.
• Commonly used in truck front axles, heavy machinery, and reducers.
3. Four-Row Tapered Roller Bearings
• Specially designed for high-load, low-speed applications.
• Typically used in steel mill rolling machines and heavy-duty industrial equipment.
4. Precision Tapered Roller Bearings
• Available in P4 and P2 accuracy grades.
• Commonly used in machine tool spindles and high-precision transmission systems.
