The 7303 bearing is a high-precision, single-row angular contact ball bearing designed to accommodate combined loads—simultaneously supporting both radial and axial forces. With its specific dimensions of a 17mm bore diameter, 47mm outer diameter, and 14mm thickness, this bearing is a key component in applications requiring high rotational speeds and significant axial rigidity. Its compact design and robust performance make it a core component in equipment requiring precise load distribution and stable rotation, serving industries from machinery to automotive.
The angular contact structure enables it to bear both radial loads and significant unidirectional axial loads, suitable for mechanical parts under composite stress.
Precision-machined raceways and high-quality balls ensure low radial runout and high rotational accuracy, maintaining stable operation of high-precision equipment.
Available with different contact angles (15° for high speed, 40° for heavy axial load), allowing customization to match diverse application requirements.
Made of high-strength bearing steel with heat treatment, it resists wear and high temperatures; optimized cage design reduces friction, extending service life and saving energy.
Used in small and medium-sized AC/DC motors, centrifugal pumps, and vacuum pumps, enduring combined loads during high-speed rotation.
Applied in spindle components of light machine tools (e.g., drilling machines, milling machines) and auxiliary shafts, ensuring precise machining accuracy.
Fits automotive transmission auxiliary shafts, steering systems, and small electrical parts (e.g., alternators), adapting to vehicle vibration and load changes.
Suitable for rotating parts of medical equipment (e.g., small centrifuges), optical instruments, and textile machine drafting shafts, requiring high precision and stability.
