7026 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7026 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to the stringent P4A tolerance class, it is engineered to handle combined loads efficiently. Its universal matchable (SU) design allows two bearings to be paired in a back-to-back or face-to-face arrangement, simplifying mounting and providing excellent operational stability. This bearing is pre-lubricated and features an extra light preload (Class A), making it an ideal, ready-to-install solution for high-speed and high-precision machinery.
7026 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7026 | Basic bearing designation indicating the standard metric dimensions (130mm bore, 200mm OD, 66mm width). |
| CD | Indicates a 15° contact angle and specifies the internal design optimized for high-speed operation. |
| P4A | Denotes a very high precision tolerance class, exceeding ABEC 7 standards, for superior running accuracy. |
| DGA | Specifies the universal matchable (SU) pairing designation and the extra light preload (Class A). |
7026 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and robust construction enable the bearing to support significant combined radial and axial loads simultaneously, providing a stable and rigid support structure.
- Superior High-Speed Performance: The phenolic resin cage offers low weight and excellent performance at high speeds, contributing to a limiting speed of 11,000 rpm. The optimized 15° contact angle further enhances high-speed suitability.
- Exceptional Precision: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring minimal runout and vibration for ultra-precise applications.
- Optimized Internal Geometry: The design, featuring 21 high-grade chrome steel balls, ensures smooth operation, low heat generation, and extended service life under demanding conditions.
