7201 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7201 ACD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to a P4A tolerance class, it is capable of simultaneously supporting combined loads (radial and axial) with high reliability. Its universal matchable (SU) design allows for flexible mounting in preloaded sets, providing high system rigidity and rotational precision. The phenolic cage and optimized contact angle of 25° contribute to its superior high-speed performance, making it an ideal choice for high-precision spindles and machinery.
7201 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | High-Precision, Double-Row bearing design. |
| P4A | Indicates a super-precision tolerance class with enhanced running accuracy and dimensional stability. |
| DGA | Universal Matchable (SU) designation, allowing two bearings to be mounted in a preloaded arrangement. |
7201 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design provides superior radial and axial rigidity, enabling the bearing to handle significant combined loads effectively. With a dynamic load rating of 2077 lbf, it ensures long-term operational stability.
- Superior High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces and friction, supporting a high limiting speed of 95,000 rpm. The optimized 25° contact angle is ideal for high-speed applications requiring both radial and axial load support.
- Precision Engineering: Manufactured to P4A super-precision standards, this bearing guarantees minimal runout and vibration, which is critical for applications requiring extreme positional accuracy.
- Universal Matching Capability: The Universal Matchable (SU) feature allows for simplified installation and precise preload control when used in pairs, eliminating the need for selective mounting and reducing assembly time.
