7032 ACD/P4A Bearing Product Overview & Core Advantages
The 7032 ACD/P4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining feature is the 25° contact angle and availability with preload, which provides exceptional axial rigidity and accuracy in positioning. Manufactured to the stringent P4 (ABEC-7) tolerance class, this bearing is designed to handle significant combined loads (radial and axial) simultaneously, making it an ideal component for demanding machinery where precision and reliability are paramount.
7032 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7032 | Basic bearing series, indicating a 160mm bore, 240mm OD, and 38mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a high-capacity internal design with larger and more balls. |
| P4A | Indicates a P4 (ABEC-7) tolerance class and specific running accuracy requirements for the shaft and housing seat. |
7032 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and optimized internal geometry enable the bearing to support substantial combined loads. The high radial dynamic load rating of 40,950 lbf and static load rating of 45,900 lbf ensure reliable performance under heavy-duty conditions.
- High-Speed Performance: The lightweight and robust phenolic resin cage ensures stable operation and guidance of the balls at high rotational speeds, contributing to the impressive limiting speed of 7,500 rpm.
- Precision and Accuracy: Conforming to the P4 tolerance class, this bearing guarantees minimal runout and precise rotational accuracy, which is critical for applications like machine tool spindles.
- Material Quality: Constructed from high-grade chrome steel for both rings and balls, the bearing offers excellent durability, wear resistance, and a long operational life.
7032 ACD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for applications requiring high speed, rigidity, and accuracy. Key industries and equipment include:
- Machine Tool Spindles (milling, grinding, and lathes)
- High-Frequency Motors and Spindles
- Precision Gearboxes
- Pumps and Compressors
- Medical and Laboratory Equipment
