S7003 ACEGA/P4A Bearing Product Overview & Core Advantages
The S7003 ACEGA/P4A is a super-precision angular contact ball bearing designed for the most demanding high-speed and high-rigidity applications. As a single bearing that is universally matchable (SU), it can be paired with an identical bearing to create a precisely preloaded set capable of withstanding combined loads—significant radial and axial loads in both directions. Its P4A tolerance class ensures exceptional running accuracy, making it ideal for spindles and other high-precision machinery requiring superior rotational stability and minimal vibration.
S7003 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7003 | Super-precision bearing series with 17mm bore, 35mm OD. |
| AC | 25° contact angle, optimized for high axial load capacity. |
| EGA | Preloaded to Extra Light (Class A) for high rigidity and minimal deflection. |
| P4A | Tolerance class superior to ABEC 7, guaranteeing extreme dimensional and running accuracy. |
S7003 ACEGA/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The phenolic cage, combined with the P4A tolerance class and extra light preload, delivers exceptional dimensional stability and rotational accuracy, crucial for minimizing runout in high-speed spindles.
Superior Load Capacity: The 25° contact angle and robust construction enable the bearing to handle significant combined radial and axial loads simultaneously.
Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, and the grease lubrication is formulated for stable operation up to the limiting speed of 103,000 rpm.
Sealed and Ready-to-Use: As a sealed bearing, it is protected from contamination and comes pre-lubricated with high-performance grease, ensuring long service life and reliability in critical applications.
