7026 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7026 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-set pair, it is engineered to accommodate combined loads—simultaneously handling significant radial and axial forces. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and other high-precision machinery. The phenolic cage and optimized 15° contact angle contribute to superior high-speed performance and smooth operation.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| CD | Universal Matchable bearing design. Two bearings can be mounted in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement to optimize load distribution and system rigidity. |
| P4A | Indicates a super-precision tolerance class, exceeding ABEC 7/ISO P4 standards. This ensures minimal runout and vibration for critical high-speed applications. |
| DGC | Specifies a Moderate preload (Class C). The preload eliminates internal clearance, enhancing system stiffness and positioning accuracy from start-up. |
7026 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The universal matchable pair and moderate preload create an exceptionally rigid bearing system capable of withstanding heavy combined radial and axial loads. The robust construction, with a radial dynamic load rating of 54,450 lbf, ensures long-term operational stability.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the 15° contact angle is optimized for high-speed operation, enabling a limiting speed of 11,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on bore, outside diameter, and width, this bearing guarantees minimal vibration and exceptional running accuracy for demanding applications.
- Optimized for Matched Sets: Supplied as a precision-matched pair (Number of bearings in matched set: 2), ensuring balanced load sharing and simplified installation for complex bearing arrangements.
