7214 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7214 ACD/P4ADGC is a high-precision double row angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads from both directions, its compact design offers a robust solution for high-reliability machinery. This bearing features a P4A tolerance class for superior running accuracy, a universal matchable (SU) design for simplified mounting in pairs, and is pre-lubricated for immediate operation. It represents an ideal choice for spindles and other precision systems where high rigidity and precise rotational performance are critical.
7214 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7214 | Basic bearing series, indicating a 70 mm bore, 125 mm OD, and 48 mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Double row design for high load capacity and rigidity. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards for enhanced running accuracy. |
| DGC | Indicates a universal matchable (SU) bearing. Two bearings can be mounted in a back-to-back (DB) or face-to-face (DF) arrangement without selective shimming. |
7214 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness, enabling the bearing to support significant combined loads (radial and bidirectional axial loads) without sacrificing performance.
- Precision Performance: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration, which is crucial for high-speed, high-accuracy applications.
- Optimized High-Speed Capability: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 28,000 rpm. The standard 25° contact angle is well-suited for high-speed operation.
- Simplified Mounting & Preload: The Universal Matchable (SU) design allows for direct pairing, achieving a defined moderate preload (Class C) that enhances system rigidity and accuracy without complex calculations or additional components.
- Durable Construction: Components made from chrome steel offer high fatigue resistance and durability, ensuring a long service life under demanding conditions.
7214 ACD/P4ADGC Bearing Typical Application Areas
This bearing is engineered for high-performance machinery, including:
- Machine Tool Spindles: For milling, grinding, and turning centers requiring high precision and rigidity.
- High-Speed Machining Centers: Where exceptional rotational accuracy and speed are paramount.
- Precision Grinding Spindles: Demanding applications with combined loads and minimal runout tolerance.
- Industrial Pumps & Compressors: For reliable operation under significant axial and radial forces.
