6203ZZ – Deep groove ball bearing

The 6203ZZ bearing is a versatile and widely-used single row deep groove ball bearing renowned for its robustness and reliability in various industrial and automotive applications. Featuring dimensions typically including a 17 mm bore diameter, 40 mm outside diameter, and 12 mm width, it provides a compact yet sturdy solution capable of efficiently handling both radial and axial loads. One of the distinguishing features of the 6203ZZ bearing is its metal shields on both sides (ZZ), which offer moderate protection against contaminants such as dust and debris. This shielding makes it particularly suitable for environments where there are moderate levels of contamination, ensuring prolonged bearing life and consistent performance. Constructed with a pressed steel cage, the 6203ZZ bearing ensures proper ball guidance under load, supported by its normal radial internal clearance that facilitates smooth operation under standard conditions. Lubricated with grease, it operates effectively within a temperature range typically spanning from -30°C to +120°C, making it adaptable to diverse operational environments.
