7005 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 7005 CE/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. As a universal matchable (SU) bearing supplied in a pre-lubricated set of two, it enables simplified installation and optimal performance in high-speed configurations. Its ceramic balls and P4A super-precision tolerance deliver superior rotational accuracy, reduced friction, and extended service life, making it ideal for applications where high rigidity and reliability are critical.
7005 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7005 | Standard bearing series designation with 25mm bore, 47mm OD |
| CE | Ceramic balls (Silicon Nitride) for reduced weight and superior high-speed performance |
| HC | Phenolic (resin) cage for reduced friction and excellent high-speed capability |
| P4A | Super precision tolerance class (ABEC 7 equivalent) for extreme rotational accuracy |
| DGA | Universal matchable pair (SU designation) with extra light preload (Class A) |
7005 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of ceramic balls and phenolic cage significantly reduces centrifugal forces and friction, enabling operation at limiting speeds of 56,000 rpm.
- Superior Rigidity & Load Capacity: The 15° contact angle and precision-ground raceways provide excellent combined load capacity (3038 lbf dynamic / 1868 lbf static), ensuring stable operation under complex loading conditions.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), delivering exceptional running accuracy and minimal vibration.
- Thermal Stability: Phenolic cage material offers excellent dimensional stability across the operating temperature range (-30°C to 110°C), maintaining precision under thermal variation.
- Pre-lubricated & Matched Set: Supplied as a universal matchable pair with factory-applied lubrication, ensuring optimal preload and performance without additional adjustment.
