S7006 ACEGA/HCP4A Bearing Product Overview & Core Advantages
The S7006 ACEGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single bearing features a 25° contact angle and is manufactured to P4A super-precision tolerance, ensuring minimal runout and superior rotational accuracy. Its core advantages include the ability to handle combined radial and axial loads simultaneously, excellent high-speed capability facilitated by its phenolic cage and ceramic balls, and long service life due to its sealed and pre-greased design. This bearing is Universal Matchable (SU), allowing for precise preload control when mounted in pairs, making it ideal for high-rigidity, high-reliability spindles and precision machinery.
S7006 ACEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7006 | Basic bearing series designation, indicating a 30mm bore, 55mm OD, and 13mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| EGA | Precision class designation and internal design features for high performance. |
| HC | Indicates the use of Hybrid Ceramic balls (Ceramic balls with steel rings). |
| P4A | Denotes a super-precision tolerance class, superior to ABEC 7, for extreme running accuracy. |
S7006 ACEGA/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and extends bearing life, especially at very high speeds (up to 71,500 rpm).
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction, contributing to smooth operation and high limiting speed.
- Super-Precision P4A Tolerance: Guarantees tight control over bearing dimensions and running accuracy, resulting in superior system performance, reduced vibration, and enhanced positional accuracy.
- Sealed & Pre-Lubricated: The integrated seals protect against contamination and retain grease, providing a maintenance-free solution for the designated temperature range (-30°C to 110°C).
- Universal Matching (SU): Allows for flexible mounting arrangements. Two bearings can be universally matched to achieve a specific preload (Extra Light / Class A in this case), simplifying installation and optimizing stiffness and running accuracy.
S7006 ACEGA/HCP4A Bearing Typical Application Areas
