S7007 CD/P4A Bearing Product Overview & Core Advantages
The S7007 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under P4 (ABEC-7) tolerance class, it is engineered to handle combined loads—simultaneous radial and axial loads—with high reliability. Its compact design, featuring a 35 mm bore and 14 mm width, makes it ideal for space-constrained, high-performance assemblies. The bearing is preloaded and pre-lubricated, ensuring immediate operational readiness, high running accuracy, and stable performance at elevated limiting speeds.
S7007 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Basic bearing series designation. |
| C | Specifies a 15° contact angle, optimized for high-speed applications requiring high axial rigidity. |
| D | Indicates a duplex arrangement (two bearings mounted as a pair). |
| P4 | Denotes high precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration. |
| A | Indicates a specific preload level for optimal stiffness and rotational accuracy. |
S7007 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 15° contact angle and P4 precision provides superior axial and radial stiffness, minimizing deflection under load for exceptional positional accuracy.
- Superior Load Capacity: Engineered to support combined loads efficiently. The dynamic and static load ratings of 3510 lbf and 2138 lbf, respectively, ensure reliable performance in demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components contribute to a high limiting speed of 24,000 rpm.
- Sealed and Lubricated for Longevity: As a sealed bearing, it is protected from contamination. Pre-lubrication ensures immediate operation and reduces maintenance needs across its specified temperature range (-30°C to 110°C).
S7007 CD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-speed, high-accuracy machinery, including:
- Machine Tool Spindles
- High-Frequency Electric Spindles
- Precision Grinding Equipment
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
