S7002 ACEGA/HCP4A Bearing Product Overview & Core Advantages
The S7002 ACEGA/HCP4A is a high-precision double row angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered to accommodate combined radial and axial loads from both directions simultaneously, this bearing features a compact cross-section. Its extra light preload (Class A) and P4A super-precision tolerance ensure smooth, quiet operation and minimal runout, making it an ideal choice for high-speed spindles and other precision machinery where rotational accuracy is paramount.
S7002 ACEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S7002 | Bearing series and size designation (15mm bore, 32mm OD) | Defines the core bearing dimensions. |
| AC | 25° Contact Angle | Optimized for high axial load capacity and rigidity. |
| EGA | Pre-greased with a specific high-performance grease | Ensures immediate operation and long-term lubrication. |
| HC | Hybrid Ceramic (Ceramic balls with steel rings) | Enables higher limiting speeds, reduced friction, and longer service life. |
| P4A | Super Precision Tolerance Class | Guarantees extremely tight dimensional and running accuracy for superior performance. |
S7002 ACEGA/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior radial and axial stiffness, effectively handling combined loads and moment loads. The 25° contact angle is optimized for significant axial load support.
- Exceptional High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage significantly increases the limiting speed to 95,000 rpm, making it a true high-speed bearing.
- Precision & Stability: Manufactured to P4A tolerance standards with an extra light preload, this bearing delivers minimal vibration and exceptional running accuracy, which is critical for applications like machine tool spindles.
- Universal Matching & Sealed Design: As a Universal Matchable (SU) bearing, it can be mounted in various preload configurations (e.g., back-to-back, face-to-face) with other bearings from a matched set. The sealed construction protects against contamination and retains lubrication.
S7002 ACEGA/HCP4A Bearing Typical Application Areas
The S7002 ACEGA/HCP4A is ideally suited for high-performance machinery where precision, speed, and reliability are non-negotiable. Key applications include:
- High-Frequency Machine Tool Spindles
- Precision Grinding Spindles
- High-Speed Robotics and Automation
- Dental and Medical Handpieces
- Aerospace Instrumentation
