7001 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7001 ACD/P4ADGA is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Manufactured to P4A tolerance class, it guarantees minimal runout and superior dimensional stability. Its 25° contact angle and Universal Matchable (SU) design enable it to efficiently handle combined loads (radial and axial) in either direction when mounted in pairs. The phenolic cage and optimized internal geometry contribute to its high-speed capabilities, making it an ideal solution for high-performance spindles and precision machinery.
7001 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 7001 | Basic bearing series and size designation | Defines the core dimensions: 12mm bore, 28mm OD, 16mm width. |
| AC | Angular Contact design | Optimized for combined radial and axial loads. |
| D | High contact angle (25°) | Provides superior axial load capacity and rigidity. |
| P4A | Super Precision Tolerance Class | Ensures extremely tight dimensional and running accuracy for high-speed, high-precision applications. |
| GA | Universal Matchable (SU) arrangement | Bearings are supplied as a pre-matched pair (2 bearings) with optimized preload for simplified installation and optimal performance. |
7001 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle provides excellent resistance to deflection under combined loads. The Universal Matchable (SU) pairing creates a rigid, preloaded bearing system.
- Super-Precision Performance: Manufactured to P4A tolerance class, this bearing ensures minimal vibration and exceptional running accuracy, which is critical for applications like machine tool spindles.
- High-Speed Capability: The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry and chrome steel construction allow for a high limiting speed of 110,000 rpm.
- Optimized for Matched Sets: Supplied as a pre-selected pair (2 bearings), this configuration simplifies mounting and ensures consistent, pre-determined preload (Extra light / Class A) for immediate, optimal performance.
7001 ACD/P4ADGA Bearing Typical Application Areas
This bearing is engineered for high-performance applications where precision, speed, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: Measuring devices, optical scanners, and coordinate measuring machines (CMM).
- High-Frequency Spindles: PCB drilling and routing spindles.
- Robotics: High-accuracy joints and actuators.
