Double Row Tapered Roller Bearings

Overview of Double Row Tapered Roller Bearings

Double row tapered roller bearings are engineered with two rows of tapered rollers arranged back-to-back, allowing them to support substantial radial loads and axial loads in both directions. Their construction provides a higher load capacity and stiffness compared to single row designs, making them suitable for applications requiring high precision and strength under heavy operating conditions.

Construction and Variants

This bearing type is available in several configurations to meet different installation and performance requirements:

• Complete Bearing Assemblies – Pre-matched cones and cups, ready for direct installation
• Cones (Inner Ring Assemblies) – Contain the inner ring and tapered rollers with a cage
• Cups (Outer Rings) – Provide the outer raceway surface for the rollers

The components can be selected individually or as a matched set, offering flexibility for replacement or customized assembly design.

Key Features

• Supports high radial loads and axial loads in both directions
• High stiffness and dimensional stability
• Available in multiple designs to suit various applications
• Reduced bearing clearance for better alignment and rigidity
• Interchangeable with products from leading global brands

Applications

Double Row Tapered Roller Bearings are widely used in:

• Heavy-duty gearboxes and reduction drives
• Steel mills and mining equipment
• Railway axle boxes and traction motors
• Construction machinery and large mechanical systems

Selection and Customization

Depending on load requirements, dimensional constraints, and operating environments, users can select from three component types: full bearing assemblies, individual cones, or cups. This modular approach allows greater flexibility in design and maintenance planning.

Conclusion

Built for strength and stability, Double Row Tapered Roller Bearings are a trusted solution for high-load, high-precision applications. With various configurations and interchangeability with major brands, they support long service life and optimized performance in the most demanding environments.
