7032 ACD/P4AQBCA Bearing Product Overview & Core Advantages
The 7032 ACD/P4AQBCA is a high-precision quadruplex matched bearing set designed for demanding applications requiring exceptional rigidity and accuracy. This metric angular contact ball bearing configuration features a back-to-back arrangement (QBC) of four bearings, providing superior stability under combined loads and significant resistance to moment loads. Manufactured to a P4A tolerance class, it delivers ultra-precise running accuracy. The extra light preload (Class A) ensures minimal friction and optimal performance in high-speed, high-rigidity scenarios, making it an ideal solution for the most critical spindle applications.
7032 ACD/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7032 | Standard bearing series number, indicating bearing dimensions (160mm bore, 240mm OD, 152mm width). |
| ACD | Angular Contact Design with a 25° contact angle for optimal axial load capacity. |
| P4A | Indicates a super-precision tolerance class, exceeding ABEC-7/ISO P4 standards for enhanced running accuracy. |
| QBC | Denotes a Quadruplex Back-to-Back matched set. Four bearings are supplied as a pre-matched unit for maximum system rigidity. |
7032 ACD/P4AQBCA Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The quadruplex back-to-back (QBC) arrangement creates an extremely rigid bearing system capable of withstanding heavy combined radial and axial loads, as well as tilting moments. This design is critical for maintaining precision under heavy cutting forces.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio, reduced centrifugal forces, and smooth operation at the limiting speed of 7,500 rpm. The 25° contact angle provides a balanced performance for both high-speed and load-carrying requirements.
Precision and Longevity: Manufactured from chrome steel for both rings and balls, and held to P4A tolerances, this bearing ensures minimal runout and consistent performance. The set is pre-lubricated for immediate installation and initial operation.
7032 ACD/P4AQBCA Bearing Typical Application Areas
This precision bearing set is engineered for the most demanding high-precision machinery, including:
- High-Speed Machine Tool Spindles (e.g., CNC machining centers, grinders)
- Precision Grinding Spindles
- High-performance High-Frequency Motor Spindles
- Other industrial equipment requiring ultra-high rigidity and running accuracy.
