Double Row Ball Bearings: Superior Performance and Reliability

Double row ball bearings offer significant advantages over their single-row counterparts, providing increased load capacity, improved rigidity, and enhanced stability for a wide range of applications. These bearings feature two rows of balls running between an inner and outer raceway, significantly increasing their radial load-carrying capacity and stiffness. This makes them ideal for applications requiring high precision and demanding operating conditions.

Key Features & Benefits:

• High Load Capacity: The dual row of balls distributes the load more effectively, resulting in a much higher radial load-carrying capacity compared to single-row bearings. This allows them to handle heavier loads and operate under more demanding conditions without premature failure.
• Increased Rigidity and Stability: The double row configuration provides superior rigidity and reduces shaft deflection, leading to increased accuracy and stability in high-speed applications. This is especially beneficial in applications where precise alignment and minimal vibration are critical.
• Improved Alignment: Double row bearings are more tolerant of misalignment compared to single-row bearings. This makes them a robust choice for applications where perfect shaft and housing alignment is difficult to achieve or maintain.
• Reduced Vibration and Noise: The enhanced rigidity and load distribution contribute to reduced vibration and noise levels during operation, leading to smoother, quieter performance.
• Variety of Configurations: Available in a wide range of sizes, materials (e.g., chrome steel, stainless steel), and configurations (including self-aligning options) to meet diverse application needs. Specific configurations offer varying levels of axial load capacity.
• Long Service Life: Properly selected and maintained double row ball bearings offer a significantly extended service life due to their robust design and higher load capacity.

Typical Applications:

• Automotive: Wheel hubs, transmissions, and other high-load components.
• Industrial Machinery: Conveyors, pumps, gearboxes, and other heavy-duty equipment.
• Robotics: Joints and actuators requiring high precision and load capacity.
• Aerospace: High-speed rotating machinery and precision instruments.
• Agricultural Machinery: Heavy-duty equipment subject to shock loads and vibrations.

Specifications (General - Specifics Vary by Model):

• Bore Diameter: Available in a wide range of bore diameters to suit various shaft sizes.
• Outside Diameter: Determined by the bore diameter and bearing width.
• Width: Varies depending on the bearing's load capacity and design.
• Dynamic Load Rating (C): Indicates the bearing's capacity for dynamic loads.
• Static Load Rating (C0): Indicates the bearing's capacity for static loads.
• Operating Temperature Range: Typically within a broad range, depending on the bearing material.

Choosing the Right Double Row Ball Bearing:

Selecting the appropriate double row ball bearing requires careful consideration of several factors, including the application's load requirements, speed, operating temperature, and desired service life. Consulting a bearing specialist or referring to bearing manufacturer catalogs is recommended for precise selection.

Note: Proper lubrication and maintenance are crucial for maximizing the lifespan and performance of double row ball bearings. Consult the manufacturer's instructions for recommended lubrication procedures and operating conditions.
