7013 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7013 ACD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under a P4A tolerance class, this bearing excels in handling combined loads, efficiently supporting significant radial loads alongside thrust loads in one direction. Its universal matchable (SU) design allows two bearings to be paired in a back-to-back or face-to-face arrangement, optimizing system performance and simplifying mounting. The combination of a phenolic cage, moderate preload (Class C), and factory-applied lubrication makes it an ideal solution for high-speed and high-reliability machinery.
7013 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class with very tight running accuracy limits. |
| DGC | Signifies a universal matchable (SU) bearing, supplied with moderate preload (Class C). |
7013 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized internal geometry, including a 25° contact angle and robust construction, provides high rigidity, enabling the bearing to handle demanding combined radial and axial loads.
- Superior High-Speed Performance: The lightweight and durable phenolic cage ensures stable operation and low friction at high rotational speeds, with a limiting speed of 31,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and exceptional dimensional stability for applications requiring supreme accuracy.
- Optimized for Matched Sets: The Universal Matchable (SU) feature allows for precise pairing, creating a pre-stressed bearing system that enhances spindle stiffness and overall performance.
