7213 ACD/P4ADFB Bearing Product Overview & Core Advantages
The 7213 ACD/P4ADFB is a precision duplex angular contact ball bearing specifically designed for applications demanding exceptional rigidity and running accuracy. This metric system bearing features a Face-to-Face (DF) matched arrangement and a Light preload (Class B), making it ideal for supporting combined loads (radial and axial) in both directions with high stability. Manufactured to P4A tolerance class, it offers superior dimensional precision and rotational accuracy, ensuring reliable performance in high-speed, high-precision machinery.
7213 ACD/P4ADFB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7213 ACD/P4ADFB is decoded as follows:
- 7213: Basic series designation, indicating a light preload duplex angular contact bearing with a 65mm bore, 120mm OD, and 46mm width.
- A: Denotes a 25° contact angle, optimized for carrying higher axial loads.
- CD: Indicates a duplex bearing in a Face-to-Face (DF) arrangement.
- P4A: Specifies the tolerance class, representing very high precision for both dimensional and running accuracy.
- DF: Confirms the Duplex Face-to-Face mounting configuration.
- B: Denotes the Light preload level (Class B).
7213 ACD/P4ADFB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex DF arrangement and light preload create a highly rigid bearing system that effectively resists moment loads and shaft deflection, ensuring precise shaft positioning.
- Superior Load Capacity: With a 25° contact angle and a dynamic load rating of 23,400 lbf, this bearing is engineered to handle significant combined radial and axial loads from both directions simultaneously.
- Precision & High-Speed Performance: The P4A tolerance class guarantees minimal runout and smooth operation. The phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 36,000 rpm, suitable for demanding high-speed applications.
- Optimized Material & Lubrication: Components made from chrome steel provide high durability and fatigue resistance. The bearing comes pre-lubricated for immediate use and reliable operation within a temperature range of -30°C to 110°C.
7213 ACD/P4ADFB Bearing Typical Application Areas
This high-precision duplex bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring extreme rigidity and accuracy.
- Precision Gearboxes and High-Frequency Motors.
- Industrial Pumps and Compressors that operate at high rotational speeds.
- Medical Equipment and Analytical Instruments demanding quiet and precise motion control.
