7204 AC P4A GA Angular Contact Ball Bearing 20x47x14mm 25° High Axial Load for CNC Spindle
7204 AC P4A GA Angular Contact Ball Bearing

The 7204 AC P4A GA features a 25° (AC-type) contact angle that provides substantially higher axial load capacity compared to its C-type counterpart. Designed for applications where both speed and axial rigidity are critical, this bearing excels in CNC spindles performing heavy cutting and drilling operations at up to 30,000 RPM.

Key Features
  • 25° Contact Angle: Significantly higher axial load capacity than standard 15° designs — ideal for thrust-heavy machining.
  • High-Speed Capability: 30,000 RPM grease limit and 45,000 RPM oil limit with ceramic ball options extending to 53,000 RPM.
  • P4A Precision Grade: Maintains exceptional geometric accuracy and minimal runout under combined loading.
  • Imported G5 Steel Balls: Delivers smooth, vibration-free rotation with extended fatigue life.
  • Kluberspeed NBU15 Grease: Ensures consistent lubrication and thermal management at elevated speeds.
