7013 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7013 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Engineered to the exacting P4A tolerance class, this bearing is optimized to handle combined loads—significant radial loads alongside axial loads in one direction. Its extra light preload (Class A) minimizes deflection under operational stresses, ensuring high running accuracy and stability. The Universal Matchable (SU) design allows for simplified mounting in pairs to accommodate bidirectional axial loads, making it an ideal choice for high-performance spindles and precision machinery.
7013 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Standard bearing series designation, indicating a 65mm bore, 100mm OD, and 36mm width. |
| CD | Indicates a Universal Matchable (SU) bearing designed to be mounted in pairs (duplex). |
| P4A | Specifies the high-precision tolerance class, exceeding ABEC-7 standards for superior running accuracy. |
| DGA | Denotes an Extra Light Preload (Class A) for minimal deflection and optimal high-speed performance. |
7013 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 15° contact angle and P4A tolerance class provide superior rigidity and running accuracy, essential for applications like machine tool spindles.
- Optimized Load Capacity: Engineered to handle combined radial and axial loads efficiently. With a dynamic load rating of 15,210 lbf and static load rating of 16,875 lbf, it offers reliable performance under demanding conditions.
- High-Speed Capability: The phenolic cage and open design contribute to a high limiting speed of 24,000 rpm, making it suitable for high-speed applications.
- Universal Matching Design: The SU designation allows for simplified pairing (in sets of 2) to handle bidirectional axial thrust without complex calculations, reducing assembly time and cost.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability and wear resistance in a wide temperature range of -30°C to 110°C.
7013 CD/P4ADGA Bearing Typical Application Areas
- Machine Tool Spindles: High-precision milling, grinding, and turning centers.
- High-Speed Machining Centers: Where accuracy and speed are critical.
- Precision Robotic Systems: Joints and rotary actuators requiring high rigidity.
- Medical Equipment: High-speed dental handpieces and imaging scanners.
