1. Product Overview & Specifications

High-precision angular contact ball bearings (7201-7206 series) are designed for complex load conditions requiring axial/radial load capacity, high-speed performance, and minimal friction. Key parameters:

Model Bore (mm) OD (mm) Width (mm) Dynamic Load (kN) Speed Rating (rpm)
7201 12 32 10 5.12 22,000
7202 15 35 11 6.85 20,000
7203 17 40 12 9.32 18,000
7204 20 47 14 13.5 16,000
7205 25 52 15 15.8 14,000
7206 30 62 16 19.2 12,000

Key Differentiation: 7206 bearings offer 27% higher dynamic load capacity than 7205 models, while 7201 series achieves 18% higher RPM tolerance than competitors.

2. Industrial Applications

Optimized for precision-driven industries:

  • Machine Tools: CNC spindle bearings (7204/7205 preferred)
  • Robotics: Articulated joint bearings (7201/7202 series)
  • Aerospace: Actuator systems (7203 with ceramic hybrids)
  • EV Motors: 7206 bearings with 0.002μm Ra surface finish

    3. Bearing Selection Guide

    Critical selection factors:

    Parameter 7201-7203 7204-7206
    Axial Load Limit 1.2-3.8 kN 4.5-9.6 kN
    Lubrication Interval 800-1,200 hrs 500-800 hrs
    Operating Temp. -30°C to +120°C -20°C to +150°C

    Pro Tip: Use 7202 bearings for <50mm shafts requiring >15,000 RPM. Upgrade to hybrid ceramic (Si3N4) balls for thermal stability >200°C.

    4. Real-World Case Studies

    Case 1: Automotive Turbocharger Manufacturer

    • Client: Top 3 Chinese turbo producer
    • Problem: 7205 bearing failures at 140,000 RPM
