707 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 707 CE/HCP4ADGA is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a 15° contact angle and P4A super-precision tolerance class, making it ideal for spindle applications where high rigidity and minimal runout are critical. Its ceramic ball construction and phenolic cage enable superior high-speed performance up to 170,000 rpm, while the extra light preload (Class A) ensures smooth operation with minimal friction. This bearing is designed to handle combined loads efficiently, providing reliable performance in the most challenging environments.
707 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 707 | Standard bore diameter series (7 mm) | Compact bearing dimensions for space-constrained applications |
| CE | Ceramic balls (Silicon Nitride) | Reduced centrifugal forces, higher speed capability, and extended service life |
| HC | Phenolic resin cage | Excellent high-speed stability and reduced friction |
| P4A | Super precision tolerance class | Ultra-precise running accuracy for critical applications |
| DGA | Universal matchable bearing set (2 bearings) | Simplified mounting and optimal preload configuration in paired arrangements |
707 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
High-Speed Capability: The combination of ceramic balls and phenolic cage significantly reduces rotating mass and centrifugal forces, enabling exceptional high-speed performance up to 170,000 rpm. This makes the bearing ideal for high-frequency spindle applications.
Precision Engineering: Manufactured to P4A super-precision standards with tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing ensures minimal runout and vibration for superior machining accuracy.
Universal Matching Design: As a universal matchable (SU) bearing supplied in sets of two, it can be arranged in back-to-back (DB), face-to-face (DF), or tandem (DT) configurations without requiring selective matching, simplifying installation and maintenance.
Optimized Load Capacity: With a 15° contact angle and extra light preload, the bearing efficiently handles combined radial and axial loads while maintaining low operating torque and temperature rise.
