7001 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7001 ACD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This universal matchable (SU) bearing features a 25° contact angle and Light (Class B) preload, making it ideal for handling combined radial and axial loads simultaneously. Manufactured to P4A tolerance class, it delivers superior running accuracy and is supplied as a lubricated, pre-matched set of two bearings, ensuring optimal performance and simplified installation in high-precision machinery.
7001 ACD/P4ADGB 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 for superior dimensional and running accuracy. |
| DGB | Signifies a Universal Matchable (SU) pair of bearings supplied as a set, ready for back-to-back (DB) or face-to-face (DF) mounting. |
7001 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and 25° contact angle provide excellent resistance to combined loads. The universal matching (SU) capability allows for the creation of pre-loaded pairs, significantly increasing system rigidity and moment load capacity.
- Precision Performance: Manufactured to P4A tolerance class with a phenolic cage, this bearing ensures minimal vibration and high running accuracy, essential for high-speed applications up to 110,000 rpm.
- Optimized for High Speeds: The lightweight phenolic cage reduces centrifugal forces, while the open design and initial lubrication facilitate efficient operation at the limiting speed.
- Durable Construction: Both rings and balls are made from chrome steel, providing high hardness and wear resistance for a long service life.
7001 ACD/P4ADGB Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Medical and Dental Equipment
- Robotic Arms and Precision Gearboxes
