S7002 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The S7002 CE/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This sealed bearing features a universal matchable (SU) design, allowing two bearings to be mounted in any combination to achieve the desired preload and rigidity. Its compact design, combined with a P4A tolerance class and ceramic balls, makes it an ideal solution for high-speed spindles and other precision machinery where superior performance under combined loads is critical.
S7002 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates the use of Hybrid Ceramic Balls (Silicon Nitride), which reduce friction, heat generation, and allow for higher operating speeds. |
| HC | Specifies a Phenolic Resin Cage, which is lightweight and ideal for high-speed applications, contributing to lower centrifugal forces and smoother operation. |
| P4A | Denotes an ultra-high-precision tolerance class with very tight running accuracy, ensuring minimal vibration and superior performance. |
| DGA | Signifies that the bearing is universal matchable (SU) and comes pre-set with an Extra Light (A) preload for immediate high-accuracy performance. |
S7002 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior radial and axial stiffness, enabling it to handle significant combined loads from multiple directions simultaneously.
- Exceptional High-Speed Performance: The combination of hybrid ceramic balls and a lightweight phenolic cage minimizes friction and inertial forces, allowing for a very high limiting speed of 95,000 rpm.
- Precision & Longevity: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration. The sealed construction retains grease and protects against contamination, resulting in a long, maintenance-free service life.
- Thermal Stability: The ceramic balls have a lower coefficient of thermal expansion than steel, helping to maintain preload and accuracy over a wide temperature range (-30°C to 110°C).
S7002 CE/HCP4ADGA Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Instrumentation
- High-Frequency Motors and Spindle Drives
- Dental Handpieces and other medical equipment
- Advanced Aerospace components
