7013 ACEGA/HCP4AH1 Bearing Product Overview & Core Advantages
The 7013 ACEGA/HCP4AH1 is a single row angular contact ball bearing designed for the most demanding high-precision applications. Manufactured to an ultra-precise P4A tolerance class, this bearing is characterized by its ceramic ball construction and phenolic cage, enabling exceptional high-speed performance up to 31,000 rpm. Its 25° contact angle is optimized to handle significant axial loads in one direction while supporting radial loads, making it ideal for applications requiring superior rigidity and rotational accuracy. As a Universal Matchable (SU) bearing, it can be precisely paired with another identical bearing to form a preloaded duplex set, delivering unmatched operational stability.
7013 ACEGA/HCP4AH1 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACEGA | Specific internal design for high-speed, high-precision applications, likely including optimized internal geometry and a phenolic cage. | Enables superior high-speed capability and smooth operation. |
| HC | Hybrid Ceramic: Features ceramic balls. | Reduced weight, lower friction, higher stiffness, and extended service life, especially at high speeds. |
| P4A | High-Precision Tolerance Class (superior to ABEC 7). | Guarantees extremely tight dimensional and running accuracy for applications demanding minimal vibration and runout. |
| H | Preload: Extra Light (Class A). | Provides minimal starting torque and optimal stiffness for high-speed spindles, reducing deflection under load. |
7013 ACEGA/HCP4AH1 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls with a steel ring significantly reduces centrifugal forces, lowers operating temperature, and provides electrical insulation. This results in higher limiting speeds, reduced wear, and longer service life.
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and operates smoothly with minimal friction at high rotational speeds, contributing directly to the bearing's high-speed performance.
- High-Precision P4A Grade: With exceptionally tight bore diameter, outside diameter, and width tolerances, this bearing ensures minimal vibration and superior running accuracy, which is critical for the finish quality in precision machining.
- Universal Matching (SU): The bearing is supplied as one of a matched set of 2. When mounted in a universal arrangement (face-to-face or back-to-back), they provide a pre-defined preload, delivering high system rigidity and precise shaft positioning.
- Optimized Contact Angle: The 25° contact angle provides an excellent balance between radial and axial load carrying capacity, making it suitable for applications with significant thrust loads.
