S7010 ACB/P4ADGA Bearing Product Overview & Core Advantages
The S7010 ACB/P4ADGA is a precision double row angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. Operating under the stringent P4A tolerance class, this bearing is designed to simultaneously handle significant combined radial and axial loads from both directions. Its compact design, featuring a universal matchable (SU) configuration, allows for simplified mounting and high system rigidity. Preloaded to Extra light / Class A, it ensures minimal runout and smooth operation, making it an ideal solution for high-speed, high-precision machinery where reliability is paramount.
S7010 ACB/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing designation, indicating a 50mm bore, 80mm OD, and 32mm width. |
| ACB | Angular Contact Bearing with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class for both dimensional and running accuracy. |
| DGA | Signifies the bearing is sealed and pre-lubricated with grease. |
S7010 ACB/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 25° contact angle provide superior rigidity and enable the bearing to support substantial combined loads and bidirectional axial loads, ensuring stable performance under demanding conditions.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards and featuring a lightweight phenolic cage, the bearing achieves smooth operation and a high limiting speed of 41,000 rpm, making it suitable for high-speed applications.
- Long Service Life & Low Maintenance: The sealed construction and factory-applied grease lubrication protect against contamination and provide long-term, maintenance-free operation within a wide temperature range of -30°C to 110°C.
- Simplified Installation: The Universal Matchable (SU) designation means two bearings can be universally paired in any combination to achieve the required preload and rigidity without selective matching, streamlining the assembly process.
