7019 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7019 ACD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-loaded pair, it excels at handling combined loads—simultaneous radial and axial forces. Its P4A tolerance class ensures ultra-precise dimensions and running accuracy, making it ideal for high-speed, high-reliability machinery where minimal runout and vibration are critical.
7019 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| 7019 | Basic designation: 95 mm bore, 145 mm OD, 48 mm width. |
| ACD | Contact angle of 25° and universal matchable design (Universal Matchable - SU). |
| P4A | High-precision tolerance class with enhanced running accuracy requirements. |
| DGB | Paired set of two bearings arranged back-to-back (DB) with Light preload (Class B). |
7019 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The dual-bearing matched arrangement provides superior system stiffness, effectively managing complex combined loads and moment loads. The 25° contact angle optimizes axial load carrying capacity.
- Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees extremely tight dimensional and running accuracy, which is essential for applications requiring high positional precision.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to the high limiting speed of 15,000 rpm.
- Optimized for Matched Sets: The Universal Matchable (SU) designation means any two bearings can be paired without selective matching, simplifying inventory and assembly while maintaining performance.
7019 ACD/P4ADGB Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Machining Centers
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arm Rotary Joints
