Double Row Spherical Roller Bearing

What Are Double Row Spherical Roller Bearings?

Double row spherical roller bearings are designed with two rows of barrel-shaped rollers arranged symmetrically around the bearing axis. This configuration allows the bearing to support extremely high radial loads and accommodate axial loads in both directions. Their self-aligning property enables the bearing to compensate for angular misalignment caused by shaft deflection, mounting errors, or dynamic loads.

Key Advantages

• High Load Carrying Capacity: The dual-row roller arrangement increases the bearing’s ability to handle radial and axial loads simultaneously.
• Superior Misalignment Tolerance: Automatically compensates for shaft or housing misalignment without affecting bearing performance.
• Long Service Life: Engineered with durable materials and optimized geometry to withstand harsh environments and extend operating life.
• Low Friction & Heat Generation: Reduced internal friction enhances energy efficiency and operational stability, even under heavy-duty conditions.

Typical Applications

These bearings are widely used in industries where equipment is subject to dynamic loads, shock, and misalignment. Common applications include:

• Mining and mineral processing machinery
• Heavy construction equipment
• Steel mills and rolling mills
• Pulp and paper production lines
• Gearboxes, conveyors, and fans

Interchangeability

Double row spherical roller bearings are dimensionally interchangeable with many globally recognized brands, including:

• SKF

Conclusion

Thanks to their high load capacity, resistance to misalignment, and durability in extreme conditions, double row spherical roller bearings are the go-to solution for industrial applications that demand performance and reliability. They help minimize maintenance, extend machinery lifespan, and improve operational efficiency.
