Product Description
7205 AC P4A GA Angular Contact Ball Bearing 25x52x15mm 25° Axial Rigidity for Drilling Spindle
7205 AC P4A GA Angular Contact Ball Bearing
The 7205 AC P4A GA combines a 25° contact angle with P4A precision for applications demanding high axial rigidity at speed. The AC-type design provides superior thrust load handling, making it the preferred bearing for CNC drilling, tapping, and heavy side-milling spindles operating at up to 26,000 RPM.
Key Features
- Enhanced Axial Rigidity: 25° contact angle delivers 40% higher axial stiffness versus 15° C-type designs in the same size.
- High Preload Range: Available in A (113 N), B (420 N), and C (901 N) preload grades to match application stiffness requirements.
- P4A Precision Grade: Sub-micron dimensional accuracy ensures consistent performance across production batches.
- Imported G5 Steel Balls: Superior roundness and surface finish minimize vibration and heat generation.
- Nylon High-Speed Cage: Optimized for rapid acceleration and low friction at sustained high RPM.
