Double Row Angular Contact Ball Bearings: Precision and Durability for High-Performance Applications

Double row angular contact ball bearings are high-precision components designed to handle significant axial and radial loads simultaneously. Unlike single-row bearings, their unique construction allows for greater load capacity and rigidity, making them ideal for applications demanding exceptional performance and reliability. This superior design minimizes deflection and vibration, ensuring smoother operation and extended lifespan.

Key Features and Benefits:

• High Load Capacity: The double row configuration distributes loads more effectively, resulting in a significantly higher load capacity compared to single-row angular contact bearings. This allows for use in applications with heavier duty cycles and increased stress.
• Superior Rigidity: The dual row of balls and contact angles provide exceptional stiffness and resistance to deflection under load, maintaining precise alignment and reducing vibrations. This is crucial for applications requiring high accuracy and stability.
• High Speed Capability: Precision manufacturing and optimized geometry allow for operation at high speeds with minimal friction and heat generation. Proper lubrication is essential to maximize high-speed performance.
• Compact Design: Despite their enhanced load capacity, double row angular contact ball bearings often maintain a relatively compact footprint, making them suitable for space-constrained designs.
• Pre-lubricated Options: Many models are available pre-lubricated with high-quality grease, reducing maintenance requirements and ensuring immediate operational readiness.
• Various Materials and Configurations: Bearings are available in a variety of materials (e.g., high-carbon chromium steel, stainless steel) to suit specific application requirements and operating environments, including options with seals to protect against contaminants. Different contact angles are also available to optimize performance for specific load orientations.

Applications:

Double row angular contact ball bearings are widely used in a broad range of demanding applications, including:

• High-speed machinery: Spindles, turbines, and high-speed rotating equipment.
• Automotive industry: Transmission systems, wheel hubs, and other critical components.
• Aerospace applications: Aircraft engines, flight control systems, and gyroscopes.
• Precision instruments: Measuring devices, robotic systems, and analytical equipment.
• Industrial machinery: Conveyors, pumps, and other heavy-duty equipment.

Specifications (Typical - Specific values vary by model):

• Bore Diameter: Wide range available, from millimeters to inches.
• Outside Diameter: Dependent on bore diameter and bearing series.
• Width: Dependent on bore diameter and bearing series.
• Contact Angle: Varies depending on design and application requirements (e.g., 15°, 25°, 40°).
• Dynamic Load Rating (C): Indicates the bearing's capacity for dynamic loads.
• Static Load Rating (C0): Indicates the bearing's capacity for static loads.
• Limiting Speed (n): The maximum permissible speed for the bearing.

Selection Considerations:

When selecting double row angular contact ball bearings, consider the following factors:

• Load requirements (axial and radial): Determine the magnitude and direction of the loads the bearing will experience.
• Operating speed: Select a bearing with a limiting speed exceeding the anticipated operating speed.
• Operating environment: Choose materials and sealing options appropriate for the specific operating conditions (temperature, humidity, contaminants).
• Space limitations: Ensure the bearing's dimensions are compatible with the available space.

Note: Always consult the manufacturer's specifications and engineering data for detailed information on specific bearing models and their applications. Proper installation and maintenance are critical for optimal performance and lifespan.
