S7013 CB/P4A Bearing Product Overview & Core Advantages
The S7013 CB/P4A is a high-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 support combined loads, handling significant radial loads alongside thrust loads in one direction. Manufactured to a P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and other precision machinery. Its preloaded configuration eliminates internal clearance, providing superior system stiffness and precise shaft positioning right from installation.
Model Code Breakdown
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| CB | Specific internal clearance and preload level | Provides a controlled, moderate preload for optimal bearing rigidity and running accuracy without excessive heat generation. |
| P4A | Tolerance class equivalent to ABEC-7 | Guarantees ultra-precision dimensions and runout tolerances for high-speed, high-accuracy applications. |
S7013 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and CB preload creates a rigid bearing unit that minimizes deflection under load, ensuring exceptional positional accuracy of the shaft.
- Superior Load Capacity: Engineered to support combined radial and axial loads simultaneously. With a dynamic load rating of 3510 lbf and a static load rating of 2902 lbf, it offers reliable performance in demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel balls and raceways contribute to a high limiting speed of 18,000 rpm.
- Sealed and Lubricated for Long Life: As a sealed and pre-lubricated bearing, it is protected from contamination and is ready for immediate use, reducing maintenance requirements and extending service intervals.
- Wide Operating Temperature Range: Suitable for use in environments from -30°C to 110°C, ensuring consistent performance across various operating conditions.
S7013 CB/P4A Bearing Typical Application Areas
This bearing is specified for high-performance applications where speed, precision, and rigidity are critical. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- High-Frequency Motors and Spindles: Where minimal vibration and runout are required.
