7002 AC Super precision Angular Contact Ball Bearing designed for spindle applications in CNC machine tools. Features long life and low noise operation for demanding industrial environments.

Angular contact ball bearings are essential for applications requiring high axial load capacity and precision. Their ability to handle both radial and axial loads, combined with high-speed operation, makes them suitable for a wide range of industrial applications, including CNC machine tools and precision machinery. Proper installation, especially in pairs, ensures optimal performance and extended service life.

Angular contact ball bearings are designed primarily to handle large one-way axial loads. The larger the contact angle, the greater the load-bearing capacity. The cage material can be steel plate, brass, or engineering plastic, and the forming method is either stamping or turning, depending on the bearing type and application conditions.

• Axial and Radial Loads: Can withstand both radial and axial loads
• Contact Angle: The larger the contact angle, the higher the axial load-carrying capacity
• High Precision: High precision and high-speed bearings typically use a 15-degree contact angle
• Axial Force Impact: Under axial force, the contact angle increases, enhancing load capacity

• High-Speed Operation: Can operate at higher speeds due to design and material properties

• One-Way Axial Loads: Single row angular contact ball bearings can only handle axial loads in one direction
• Additional Axial Forces: When subjected to radial loads, they generate additional axial forces
• Axial Displacement: Can only limit axial displacement in one direction

• Opposite Outer Rings: To avoid additional axial forces and limit axial play in both directions
• Optimal Positioning: Outer rings positioned oppositely with wide end faces meeting wide end and narrow end faces meeting narrow end
