Product Description
7207 AC P4A GA Angular Contact Ball Bearing 35x72x17mm 25° Thrust Optimized for Boring Spindle
7207 AC P4A GA Angular Contact Ball Bearing
The 7207 AC P4A GA is thrust-optimized with a 25° contact angle, making it the ideal choice for boring spindles, vertical turning centers, and any application where axial load dominates. It delivers robust performance at up to 18,000 RPM with P4A precision tolerances throughout.
Key Features
- Thrust-Optimized Design: 25° contact angle maximizes axial load capacity for boring, drilling, and facing operations.
- Heavy Preload Range: Up to 1550 N (C-grade) preload for ultimate spindle stiffness in precision boring.
- P4A Precision: Maintains sub-micron accuracy under combined loading for superior bore quality and surface finish.
- Imported G5 Steel Balls: Consistent quality for reliable, long-life performance in production environments.
- Nylon High-Speed Cage: Minimizes friction and heat generation for sustained accuracy during long cycle times.
