7014 CE/HCDTGMM1VQ126 Bearing Structural Features & Performance Benefits
High Rigidity and Axial Load Capacity: The duplex tandem arrangement and built-in preload create an exceptionally rigid bearing system, capable of supporting high unidirectional axial loads and combined loads, making it ideal for precise positioning applications.
Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density, high-hardness ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 22,000 rpm and lower operating temperatures.
Enhanced Durability and Longevity: Ceramic balls offer excellent wear resistance, lower friction, and electrical insulation properties. They are also non-magnetic and can operate effectively with minimal lubrication, extending service life.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing ensures minimal runout and superior rotational accuracy.
