Product Description
7208 AC P4A GA Angular Contact Ball Bearing 40x80x18mm 25° Maximum Rigidity for Turning Center
7208 AC P4A GA Angular Contact Ball Bearing
The 7208 AC P4A GA delivers maximum axial rigidity in the 72 series lineup. With a 25° contact angle, 40mm bore, and preload options up to 1850 N, it is the definitive choice for CNC turning centers and vertical lathes where spindle stiffness directly impacts part quality at up to 16,000 RPM.
Key Features
- Maximum Axial Rigidity: 25° contact angle with up to 1850 N (C-grade) preload for ultimate spindle stiffness in heavy turning.
- Robust Load Ratings: 34.50 kN dynamic and 24.00 kN static capacity for demanding production turning operations.
- P4A Precision Grade: Ensures consistent part quality with sub-micron runout and excellent geometric accuracy.
- Imported G5 Steel Balls: Premium quality for extended service life and reduced maintenance intervals.
- Nylon Cage Technology: Optimized for sustained high-speed operation with minimal thermal expansion.
