7014 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7014 ACD/P4ADGC is a precision angular contact ball bearing manufactured to exacting P4A tolerance class standards. Engineered for applications requiring exceptional rotational accuracy and rigidity, this bearing features a 25° contact angle and Moderate (Class C) preload, making it ideal for handling combined radial and axial loads simultaneously. Its Universal Matchable (SU) design allows for flexible pairing in duplex sets to achieve specific stiffness and precision requirements. The phenolic cage and chrome steel construction contribute to its high-speed capability and durability in demanding industrial environments.
7014 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle, optimized for combined loads |
| P4A | High precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout |
| DGC | Universal Matchable (SU) bearing designed for duplex mounting (Back-to-Back/DB, Face-to-Face/DF, or Tandem/DT) |
7014 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with 25° contact angle and Moderate preload (Class C) provides superior stiffness, enabling the bearing to handle significant combined radial and axial loads (Dynamic: 17,842 lbf, Static: 19,462 lbf).
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration.
- High-Speed Capability: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 29,000 rpm, reducing centrifugal forces and maintaining stability.
- Matched Set Flexibility: As a Universal Matchable (SU) bearing, it can be paired in sets of 2 with controlled preload, allowing for customized stiffness and precision in duplex arrangements.
- Durable Construction: Made from chrome steel for rings and balls, providing excellent wear resistance and longevity in precision applications.
