7026 ACDGB/P4A Bearing Product Overview & Core Advantages
The 7026 ACDGB/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running precision and is universally matchable (SU), allowing for flexible arrangement in sets of three to optimize preload and system stiffness. Its 25° contact angle is specifically designed to handle significant combined loads—simultaneously supporting high radial and axial loads. The phenolic cage and light preload (Class B) contribute to its excellent high-speed performance, making it an ideal component for demanding, precision-driven machinery.

7026 ACDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and robust construction enable the bearing to support substantial combined radial and axial loads. The universal matchable design allows for preloaded sets, significantly increasing system rigidity.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry allows for a high limiting speed of 11,000 rpm, making it suitable for high-speed spindles.
- Precision Engineering: Manufactured to P4A tolerance class with extremely tight bore, outside diameter, and width tolerances, ensuring minimal runout and vibration for superior operational accuracy.
- Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and a long operational lifespan under demanding conditions.
