1. Product Specifications & Parameter Comparison

The NSK 7210 series angular contact ball bearings (model: 7210A, 7210B, 7210C, 7210AC) are designed for high-precision radial and axial load management. Key specifications include:

Model Contact Angle Inner Diameter (mm) Outer Diameter (mm) Dynamic Load (Cr) Static Load (Cor)
7210A 30° 50 90 43,000 N 31,500 N
7210B 40° 50 90 37,500 N 28,600 N
7210C 15° 50 90 38,000 N 29,200 N
7210AC 25° 50 90 37,500 N 28,000 N

Key Differences: Higher contact angles (e.g., 7210B) excel in axial load capacity, while lower angles (e.g., 7210C) optimize radial load performance [7][8].

2. Detailed Applications

NSK 7210 series bearings are widely used in:

  • Machine Tools: High-speed spindles requiring precision alignment.
  • Automotive Systems: Gearboxes and wheel hubs demanding dual-load capacity.
  • Industrial Pumps: Axial thrust management in centrifugal pumps.

3. Industry Use Cases

  • Robotics: 7210AC bearings in robotic arms for smooth articulation.
  • Aerospace: 7210B variants in landing gear mechanisms for heavy axial loads.

4. Real Client Case Studies

Case Study 1: Automotive Manufacturer

  • Challenge: Frequent bearing failures in electric vehicle drivetrains.
  • Solution: NSK 7210AC bearings with 25° contact angle for balanced load handling.
  • Result: 40% longer service life and reduced maintenance costs.

Case Study 2: CNC Machinery Provider

  • Challenge: Vibration issues in high-speed milling machines.
  • Solution: 7210C bearings with optimized radial stiffness.
  • Result: 98% reduction in spindle vibration.

5. Procurement Considerations

  • Verify load direction (axial vs. radial) to select contact angle.
  • Check lubrication requirements for operational environments.
  • Confirm certifications (ISO 9001) for quality assurance [4].
