7026 CD/P4ADFC Bearing Product Overview & Core Advantages
The 7026 CD/P4ADFC is a duplex face-to-face (DF) arrangement of angular contact ball bearings, engineered for applications demanding high precision and exceptional rigidity. This precision bearing set is designed to accommodate combined loads (radial and axial) simultaneously and is preloaded to Moderate / Class C standards for optimal performance in high-speed, high-accuracy scenarios. Its compact design, featuring two matched bearings, provides superior operational stability and rotational accuracy.

7026 CD/P4ADFC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex face-to-face (DF) arrangement creates a highly rigid bearing system capable of withstanding significant combined loads and moment loads. This configuration is essential for maintaining shaft positioning accuracy under demanding operating conditions.
Precision Performance: Manufactured to P4A tolerance class, these bearings ensure minimal runout and vibration, making them ideal for applications requiring high rotational accuracy.
Optimized High-Speed Operation: The phenolic cage material and 15° contact angle contribute to stable operation at the rated limiting speed of 11,000 rpm, with reduced friction and heat generation.
Superior Material Construction: Manufactured from chrome steel for both rings and balls, these bearings offer high durability, wear resistance, and long service life under heavy loads.
