7006 ACD/P4AQGC Bearing Product Overview & Core Advantages
The 7006 ACD/P4AQGC is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads simultaneously), this bearing features a 25° contact angle and a universal matchable (SU) design, allowing for flexible mounting arrangements in sets. Manufactured to a P4A tolerance class, it delivers superior running accuracy and is pre-lubricated for immediate use, making it an ideal solution for high-speed, high-reliability machinery.
7006 ACD/P4AQGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class, exceeding ABEC 7 standards for exceptional dimensional and running accuracy. |
| QGC | Specifies the internal clearance and preload condition. In this case, it denotes a Moderate preload (Class C) for optimal stiffness and performance. |
7006 ACD/P4AQGC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and moderate preload provide high axial and radial rigidity, enabling the bearing to handle significant combined loads effectively.
- Superior Precision: The P4A tolerance class ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 53,000 rpm. The 25° contact angle is well-suited for high-speed operation.
- Universal Matching Capability (SU): Bearings are universally matchable, allowing them to be mounted in pairs or sets (back-to-back, face-to-face, or tandem) without selective assembly, simplifying installation and ensuring consistent preload.
- Durable Construction: Components made from chrome steel offer high hardness and wear resistance, ensuring long service life under demanding conditions.
7006 ACD/P4AQGC Bearing Typical Application Areas
This precision bearing is ideally suited for applications where high speed, accuracy, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Drives and CNC Rotary Tables
