S7007 CB/P4A Bearing Product Overview & Core Advantages
The S7007 CB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads in one direction, this single-row bearing features a 15° contact angle and is supplied with a preload (CB) for enhanced system stiffness and precise shaft positioning. Manufactured to P4 (ABEC-7) tolerance class, it is an ideal solution for high-speed spindles and other high-reliability machinery where minimal runout and superior performance are critical.
S7007 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7007 | Basic bearing series and size designation (35mm bore, 62mm OD, 14mm width) | Defines the core bearing dimensions and internal geometry. |
| CB | Specific preload classification | Indicates a moderate, controlled preload applied during manufacturing to increase bearing rigidity and minimize axial/radial play. |
| P4A | Tolerance class designation (equivalent to ABEC-7) | Specifies extremely tight dimensional and running accuracy tolerances for high-precision applications. |
S7007 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The CB preload and P4A tolerance class work in tandem to deliver superior system stiffness, reduce vibration, and ensure precise rotational accuracy, which is critical for machining quality.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently support significant combined loads, with a high thrust capacity relative to its compact cross-section.
- High-Speed Capability: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to the high limiting speed of 32,000 rpm, making it suitable for demanding high-speed applications.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance, ensuring long-term performance in continuous operation.
