7207 ACD/P4ADBA Bearing Product Overview & Core Advantages
The 7207 ACD/P4ADBA is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability and can accommodate combined radial and axial loads from both directions. Manufactured to P4A tolerance class with an extra light preload (Class A), it delivers high running accuracy, reduced vibration, and is ideal for high-speed, high-precision spindles and machinery.
7207 ACD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7207 | Basic bearing series, indicating a 35mm bore, 72mm OD, and 34mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Duplex (two single bearings supplied as a matched set). |
| DB | Back-to-Back mounting arrangement. |
| P4A | High Precision Tolerance Class (exceeds ABEC-7), ensuring minimal runout and vibration. |
| A | Extra Light Preload (Class A), optimized for high-speed operation and reduced friction. |
7207 ACD/P4ADBA Bearing Structural Features & Performance Benefits
Optimized Rigidity and Load Capacity: The back-to-back duplex configuration creates a wide, rigid support system that effectively resists moment loads and provides excellent operational stability. This design enables the bearing to handle significant combined loads.
High-Speed Performance: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces and smoother operation at the high limiting speed of 56,000 rpm. The 25° contact angle offers a balanced performance for both radial and axial loads at high speeds.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on the bore, outside diameter, and width, this bearing guarantees high running accuracy and consistent performance in the most demanding applications.
Superior Material: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational life.
