The FAG 6203 C3 deep groove ball bearing is engineered for demanding industrial applications requiring increased internal clearance, high rotational speed and long service life. With dimensions of 17x40x12 mm, this single-row deep groove ball bearing features C3 radial internal clearance, allowing it to compensate for thermal expansion during operation. This design ensures stable performance, reduced operating stress and extended bearing life in electric motors, pumps, gearboxes and other industrial drive systems.
The FAG 6203 C3 bearing is widely used in:
The C3 internal clearance makes this bearing particularly suitable for equipment operating at elevated temperatures and high rotational speeds.
The FAG 6203 C3 is a single-row deep groove ball bearing with precision-ground raceways that provide excellent load distribution and smooth running performance. Its open design allows customized lubrication according to application requirements. The increased C3 radial clearance compensates for shaft and housing expansion caused by operating temperatures, while the Generation C internal design improves load distribution, reduces friction and enhances bearing durability.
Industry entities naturally associated with this product include:
The bearing is manufactured from premium FAG hardened chromium bearing steel with precision-machined raceways for excellent fatigue resistance and wear protection. High-quality steel balls and a pressed steel cage provide smooth operation, low vibration and reliable performance during continuous industrial operation. The optimized Generation C internal geometry further improves efficiency and operating life.
