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 dual row configuration provides superior load capacity, stiffness, and stability, making them ideal for applications demanding exceptional performance and reliability.

Key Features & Benefits:

• High Load Capacity: The double row design distributes loads more effectively, significantly increasing the bearing's capacity to withstand both radial and axial forces, even under high-speed operation. This extended load capacity minimizes wear and extends operational lifespan.
• Increased Rigidity & Stiffness: The dual contact points provide greater rigidity compared to single-row bearings, resulting in improved accuracy and reduced deflection under load. This is crucial for applications requiring precise positioning and minimal vibration.
• High-Speed Capability: Properly lubricated and designed double row angular contact bearings can operate at exceptionally high speeds, making them suitable for a wide range of dynamic applications.
• Compact Design: Despite their enhanced performance, double row angular contact bearings often maintain a compact footprint, optimizing space in machinery designs.
• Superior Axial Load Handling: These bearings excel at handling significant axial loads in one direction. Configurations are available to handle loads in either a single or dual direction depending on application needs.
• Pre-loaded Options: Many designs are available with pre-loading options, further enhancing rigidity and minimizing play for applications demanding extreme precision.
• Wide Range of Materials & Configurations: Available in various materials (e.g., high-carbon chromium steel, stainless steel) and configurations to meet specific application requirements, including different shaft and housing bore sizes, tolerances, and sealing options. Custom designs are frequently possible.

Applications:

Double row angular contact ball bearings find extensive use in demanding applications, including:

• High-speed spindles: Machine tools, precision grinders, and CNC machining centers.
• Automotive applications: Wheel hubs, transmissions, and steering systems.
• Robotics: High-precision robotic arms and manipulators.
• Aerospace components: Aircraft engines, actuators, and flight control systems.
• Industrial machinery: High-speed pumps, compressors, and turbines.

Specifications (Typical - Consult Specific Product Catalogs for Exact Values):

• Inner and Outer Diameter: Wide range available, depending on specific bearing type and size.
• Width: Varies based on bearing size and load capacity.
• Contact Angle: Typically ranges from 15° to 40°, impacting load-carrying capacity and directional load handling.
• Clearance: Defined tolerances to ensure optimal performance and longevity.
• Lubrication: Typically require grease or oil lubrication depending on the operating conditions.
• Sealing: May include integrated seals to prevent contamination and retain lubricant.

Note: Selecting the appropriate double row angular contact bearing requires careful consideration of several factors, including load capacity, speed, operating temperature, and environmental conditions. Consult with a bearing specialist to ensure optimal selection for your application. Improper selection or installation can result in premature failure.
