S7015 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7015 ACDGB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, it provides superior running accuracy for high-speed operations. Its 25° contact angle and Universal Matchable (SU) design enable it to handle significant combined loads—both radial and axial—simultaneously. This bearing is preloaded (Light / Class B) for enhanced system stiffness and is pre-lubricated with grease for immediate, reliable service, making it an ideal choice for high-performance, high-reliability machinery.
S7015 ACDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design, optimized for combined loads. |
| D | High ball count and optimized internal geometry for increased load capacity. |
| GB | Light preload (Class B) for high rigidity and precise shaft positioning. |
| P4A | Super Precision tolerance class, ensuring extremely tight running accuracy. |
S7015 ACDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single bearing design with a Light preload (Class B) ensures maximum system stiffness and minimal axial/radial play, which is critical for applications requiring high positional accuracy.
- Superior Load Capacity: With a 25° contact angle and a phenolic cage, this bearing is engineered to handle high combined loads efficiently, offering a dynamic load rating of 11115 lbf and a static load rating of 10462 lbf.
- Optimized for High Speeds: The lightweight phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 22,000 rpm, making it suitable for high-speed spindles.
- Sealed and Lubricated for Life: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is designed for long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
