Four-Point Contact Ball Bearings: Superior Precision and Load Capacity

Four-point contact ball bearings are high-precision components designed for applications demanding exceptional rigidity, load capacity, and axial positioning accuracy. Unlike single-row or double-row bearings, these bearings utilize a unique arrangement of balls and raceways to provide support in both axial directions and radial directions simultaneously. This results in a bearing capable of withstanding significantly higher loads and maintaining exceptional stability under demanding operating conditions.

Key Features and Benefits:

• High Load Capacity: The four-point contact design distributes loads effectively across multiple points, resulting in a substantially higher radial and thrust load capacity compared to single-row bearings. This makes them ideal for applications with heavy or shock loads.
• Superior Rigidity: The inherent design minimizes deflection under load, ensuring precise positioning and maintaining dimensional stability even under significant stress. This is crucial for applications requiring high accuracy and stability.
• Bi-directional Axial Positioning: These bearings provide robust axial positioning in both directions, eliminating the need for additional support components in many applications. This simplifies design and reduces overall system complexity.
• High Precision: Manufactured to stringent tolerances, four-point contact ball bearings offer exceptional rotational accuracy and smoothness, vital for high-precision machinery.
• Compact Design: Despite their high load capacity, four-point contact ball bearings often have a compact footprint, making them suitable for space-constrained applications.
• Long Service Life: The robust design and precise manufacturing contribute to a significantly longer service life compared to less robust bearing types.
• Variety of Materials and Configurations: Available in a range of materials (e.g., high-carbon chrome steel, stainless steel) to suit various operating environments and requirements, offering different configurations to address specific application needs.

Typical Applications:

• Precision Machine Tools: Lathes, milling machines, grinding machines, and other applications demanding high accuracy and rigidity.
• Robotics: Providing precise positioning and movement in robotic arms and manipulators.
• Aerospace: Used in aircraft and spacecraft applications where high load capacity and reliability are essential.
• Automotive: Found in high-precision steering systems and other components requiring exceptional stability.
• Measurement and Inspection Equipment: Critical for ensuring the accuracy and reliability of measuring instruments.
• Heavy-duty machinery: Applications such as industrial presses and rolling mills.

Specifications (Vary by Model):

• Bore Diameter: Ranges from several millimeters to several centimeters, depending on the specific model.
• Outside Diameter: Varies depending on the bore diameter and bearing design.
• Width: Dependent on the specific model and load requirements.
• Static and Dynamic Load Ratings: These critical parameters define the bearing's capacity to withstand static and dynamic loads, respectively. Specific ratings are provided in detailed technical specifications for each model.
• Material: High-carbon chrome steel, stainless steel, or other specialized materials as needed.
