S7003 ACE/P4A Bearing Product Overview & Core Advantages
The S7003 ACE/P4A is a high-precision, single-row angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to handle significant combined loads, primarily thrust loads in one direction, while supporting radial loads. Its compact design, featuring a 17 mm bore and 35 mm outside diameter, makes it ideal for space-constrained, high-speed applications such as precision spindles. The bearing comes pre-lubricated and is available with a preload, ensuring immediate high-performance operation, superior running accuracy, and minimal heat generation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|

| ACE | A 25° contact angle and enhanced internal design for high-speed, high-precision performance. |
| P4A | Indicates a P4 (ABEC-7) tolerance class with specific dimensional and running accuracy requirements for superior performance. |
S7003 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance class with a phenolic resin cage, this bearing ensures exceptional dimensional stability, low noise, and high running accuracy, which is critical for precision machining.
- Superior Load Capacity: The 25° contact angle is optimized to handle high one-direction axial loads and combined (radial and axial) loads effectively.
- Optimized High-Speed Performance: The lightweight phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 56,000 rpm, reducing centrifugal forces and operational friction.
- Sealed and Lubricated for Longevity: As a sealed bearing that comes pre-lubricated, it is protected from contamination and is ready for immediate use, offering a long service life with minimal maintenance in clean environments.
