Tapered roller bearings are a commonly used type of rolling bearing. Their core feature is that the rolling elements are conical and the raceways of the inner and outer rings are tapered, enabling them to withstand both large radial and axial loads simultaneously. They are widely applied in mechanical scenarios requiring bidirectional force bearing.

Core Structure and Working Principle

Structural Composition: Mainly consists of inner ring, outer ring, tapered rollers, and cage. Some models are equipped with sealing devices or dust covers.

Force-Bearing Principle: The conical structure forms line contact between the rollers and raceways. Loads can be decomposed into radial and axial directions through the conical contact surfaces, adapting to working conditions that need to bear both pressure and thrust.

Key Features and Advantages

Strong Load-Bearing Capacity: Capable of withstanding heavy loads and impact loads, with balanced radial and axial load-bearing performance, suitable for high-load operation scenarios.

Wide Precision Range: Products are available from ordinary precision to high-precision grades, adaptable to equipment with different speed and precision requirements.

Flexible Installation: Most adopt a separable design (the inner ring with roller assembly can be separated from the outer ring), facilitating installation, disassembly, and maintenance.

Typical Application Scenarios

Automotive Field: Hubs, gearboxes, and differentials of trucks and buses, as well as transmission systems of construction machinery.

Industrial Machinery: Machine tool spindles, reducers, mining machinery, cranes, and other equipment requiring heavy loads and axial forces.

General Machinery: Transmission components such as water pumps, fans, and printing machinery that have requirements for load-bearing capacity and stability.
