S7010 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7010 CE/P4ADGA is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing features an Extra Light (Class A) preload and is Universal Matchable (SU), allowing for versatile mounting configurations in pairs. Its primary advantage lies in its ability to handle combined radial and axial loads simultaneously with high rigidity, making it an ideal choice for high-precision spindles and other critical machinery components requiring superior running accuracy and reliability.
S7010 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7010 | Basic bearing series and size designation (50mm bore, 80mm OD). | Defines the core bearing dimensions. |
| CE | Contact angle of 15°. | Optimized for handling axial loads. |
| P4A | High-Precision Tolerance Class (equivalent to ABEC 7). | Ensures extremely tight dimensional and running accuracy for precision applications. |
| DGA | Grease lubrication, phenolic cage, universal matching. | Indicates the use of a phenolic cage for high-speed capability and universal matchable (SU) design for flexible mounting. |
S7010 CE/P4ADGA Bearing Structural Features & Performance Benefits
The performance of the S7010 CE/P4ADGA is derived from its meticulous design and material selection:
- High Rigidity & Load Capacity: The angular contact design with a 15° contact angle provides excellent resistance to combined loads. The Extra Light preload eliminates internal clearance, enhancing system stiffness and positioning accuracy.
- Superior High-Speed Performance: The lightweight, robust phenolic cage ensures stable operation and low friction at the limiting speed of 34,000 rpm. This makes it a premier high-speed bearing.
- Precision Engineering: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing guarantees minimal runout and vibration for ultra-precise applications.
- Optimized Lubrication: Pre-greased for immediate operation, the bearing operates effectively within a temperature range of -30°C to 110°C.
