7026 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The 7026 ACDGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Its core advantage lies in its ability to handle combined loads—significant radial and axial loads in one direction—simultaneously. Manufactured to P4A tolerance class, it offers superior dimensional and running accuracy. The use of a ceramic ball and phenolic cage combination contributes to its capabilities as a high-speed bearing, allowing for a limiting speed of 11,000 rpm. This bearing is pre-lubricated and features an open design, making it an ideal, ready-to-install component for high-rigidity, high-reliability systems.
7026 ACDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | High Ball Complement design for increased load capacity. |
| GA | Specifies an Extra light (Class A) preload for minimal friction and high-speed operation. |
| HC | Indicates the use of Hybrid Ceramic balls (Silicon Nitride). |
| P4A | Denotes a super-precision tolerance class, exceeding ABEC 7/ISO P4 standards. |
7026 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 25° contact angle and high ball complement provides excellent rigidity and enables the bearing to support substantial combined radial and axial loads.
- Superior High-Speed Performance: The combination of lightweight phenolic resin cage and low-density, hard ceramic balls reduces centrifugal forces, lowers operating temperatures, and enables the high limiting speed of 11,000 rpm.
- Precision and Longevity: Manufactured to P4A tolerance class with tight bearing dimensions and bore/OD tolerances, this bearing ensures smooth, quiet, and vibration-free operation, critical for precision machinery.
- Universal Matching (SU): This bearing is Universal Matchable, allowing for precise preload control when mounted in pairs or sets (typically 3 bearings in a set), simplifying installation and optimizing system performance.
