7003 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7003 ACD/P4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to a P4A tolerance class, this bearing is optimized to handle combined loads (radial and axial) simultaneously. Its universal matchable (SU) design allows two bearings to be paired in a back-to-back (DB) or face-to-face (DF) arrangement, providing superior system stability. The combination of a phenolic cage and a 25° contact angle enables high-speed operation and reliable performance in precision machinery.
7003 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7003 ACD/P4ADGA details its specific technical features:
- 7003: Basic series designation, indicating a 17mm bore, 35mm OD, and 20mm width.
- A: Denotes a 25° contact angle.
- CD: Signifies Universal Matchable (SU) bearings with a specific preload.
- P4A: Indicates a super-precision tolerance class exceeding ABEC 7, with enhanced running accuracy.
- DGA: Specifies an Extra light (Class A) preload.
7003 ACD/P4ADGA Bearing Structural Features & Performance Benefits
The 7003 ACD/P4ADGA's construction delivers distinct performance advantages:
- High Rigidity & Load Capacity: The angular contact design and universal matching capability allow for stable bearing pairs that provide high rigidity and excellent capacity for combined radial and axial loads.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized 25° contact angle and precision manufacturing contribute to a high limiting speed of 115,000 rpm.
- Precision Operation: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
