7206 AC P4A GA Angular Contact Ball Bearing 30x62x16mm 25° Heavy Duty for Milling Spindle
7206 AC P4A GA Angular Contact Ball Bearing
The 7206 AC P4A GA is engineered for heavy-duty milling and machining applications where combined axial and radial loads are substantial. With a 25° contact angle, it offers the highest thrust capacity in the 7206 size class, paired with P4A precision for 22,000 RPM operation under grease lubrication.
Key Features
- Maximum Thrust Capacity: 25° AC contact angle handles heavy axial loads up to 1357 N preload (C-grade) for aggressive cutting.
- Heavy-Duty Construction: Robust 22.00 kN dynamic and 14.00 kN static load ratings for demanding production environments.
- P4A Precision: Tight tolerances maintain spindle accuracy even under combined loading conditions.
- G5 Steel Balls: Imported precision balls ensure smooth operation and long fatigue life.
- Nylon Cage Design: Reduces inertia and operating temperature for sustained high-speed performance.
