S7030 CD/P4A Bearing Product Overview & Core Advantages
The S7030 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 15° contact angle, it is optimized to handle combined loads, accommodating high radial loads and substantial axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance, it ensures minimal runout and vibration, making it ideal for high-speed, high-precision spindles. The bearing comes preloaded and pre-lubricated from the factory, simplifying installation and providing immediate, reliable performance.
S7030 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7030 | Basic bearing series and size designation (150mm bore, 225mm OD). |
| C | Specifies a 15° contact angle. |
| D | Indicates the bearing is supplied with a preload for enhanced rigidity. |
| P4A | Denotes a P4 (ABEC-7) tolerance class for superior dimensional and running accuracy. |
S7030 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and factory-applied preload ensures maximum system stiffness, critical for minimizing deflection under load in precision machinery.
- Superior Load Capacity: Engineered to support significant combined radial and axial loads, with a dynamic load rating of 38,700 lbf and a static load rating of 42,750 lbf.
- Optimized High-Speed Performance: The lightweight, durable phenolic resin cage and precision-ground chrome steel components contribute to a high limiting speed of 6,000 rpm, reducing centrifugal forces and heat generation.
- Sealed and Lubricated for Longevity: As a sealed bearing with factory-applied lubrication, it is protected from contamination and is ready for immediate use, offering a long service life within its specified temperature range of -30°C to 110°C.
S7030 CD/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (e.g., CNC milling, grinding, and turning centers)
- High-Frequency Motors and Spindles
- Precision Gearboxes and Robotic Drives
