S7010 CD/P4ADGC Bearing Product Overview & Core Advantages
The S7010 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under P4A tolerance class, this bearing is engineered to simultaneously handle significant combined radial and axial loads. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, providing high system rigidity and operational stability. Preloaded to Moderate / Class C, it is ideal for high-speed spindles and other precision machinery where minimal deflection and superior running accuracy are critical.
S7010 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Specifies a 15° contact angle and indicates the bearing is designed for universal matching (DU/DT/DF/DB arrangements). |
| P4A | Denotes an ultra-precision tolerance class with enhanced running accuracy and dimensional stability beyond standard P4. |
| DGC | Indicates the bearing is sealed and pre-lubricated with high-performance grease suitable for the specified temperature range. |
S7010 CD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The optimized internal geometry and 15° contact angle enable the bearing to support substantial combined loads. When mounted in pairs as a universal matchable (SU) set, the system achieves exceptional rigidity, minimizing shaft deflection under load.
Precision and High-Speed Performance: Manufactured to P4A tolerance class, this bearing ensures ultra-low runout and vibration. The phenolic resin cage is lightweight and robust, contributing to smooth operation and a high limiting speed of 46,000 rpm. The moderate preload (Class C) reduces startup and running vibration, enhancing positional accuracy.
Maintenance-Free Operation: The integrated seals effectively retain the factory-applied grease lubricant and exclude contaminants. This sealed design provides long-term, maintenance-free operation within the specified temperature range of -30°C to 110°C.
S7010 CD/P4ADGC Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring extreme precision and rigidity.
- Precision Instrumentation: High-accuracy measuring devices and optical equipment.
- High-Frequency Motors and Spindles: Applications where minimal vibration and high rotational speeds are paramount.
- Industrial Pumps and Compressors: For shafts requiring precise axial location and handling of combined loads.
