Description
7205 C P4A GA Angular Contact Ball Bearing 25x52x15mm 28000RPM Precision for Motorized Spindle
7205 C P4A GA Angular Contact Ball Bearing

The 7205 C P4A GA bridges compact size with robust load capacity, making it a versatile choice for motorized spindles in CNC machining centers. Its 15° contact angle optimizes for speed while maintaining adequate axial rigidity, achieving 28,000 RPM under grease lubrication.

Key Features
  • Balanced Speed & Load: 28,000 RPM grease limit with 15.60 kN dynamic load rating — ideal for general-purpose CNC spindles.
  • P4A Precision: Manufactured to ABEC-7 equivalent tolerances for minimal radial and axial runout.
  • G5 Steel Balls: Precision-ground to sub-micron sphericity for smooth, quiet operation at all speeds.
  • Nylon Cage: Lightweight, low-friction retainer enables faster acceleration and reduced heat buildup.
  • Multiple Pairing Options: DB for balanced stiffness, DT for unidirectional thrust, TBT/QBC for high-rigidity configurations.
