S7006 ACE/P4A Bearing Product Overview & Core Advantages
The S7006 ACE/P4A is a precision angular contact ball bearing designed for applications demanding high rotational accuracy and rigidity. This single-row bearing features a 25° contact angle and is supplied with a preload, enabling it to handle significant combined loads (radial and axial) simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it ensures exceptional running accuracy and is ideal for high-speed, high-reliability applications where minimal runout and precise shaft positioning are critical.
S7006 ACE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| ACE | Specific internal design and contact angle (25°) | Optimized for high axial load capacity and rigidity. |
| P4A | P4 (ABEC-7) tolerance class with specific accuracy and running deviations. | Guarantees superior precision, smooth operation, and low noise/vibration levels. |
S7006 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and preload provide superior stiffness, effectively resisting deflection under combined loads and ensuring precise shaft guidance.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry contributes to a high limiting speed of 35,000 rpm.
- Precision Engineering: Manufactured to P4 tolerance with chrome steel rings and balls, this bearing delivers exceptional dimensional stability and long-term running accuracy.
- Sealed and Lubricated for Life: The sealed design with factory-applied lubricant protects against contamination and provides maintenance-free operation within the specified temperature range.
