6302ZZ – Deep groove ball bearing

The 6302ZZ bearing is a variant of the 6302 series, distinguished by metal shields on both sides (ZZ) that provide robust protection against contaminants such as dust and debris. This shielding makes it particularly suitable for applications where moderate to high levels of contamination are expected, ensuring prolonged bearing life and reliable performance. Typically featuring dimensions like a 15 mm bore diameter, 42 mm outside diameter, and 13 mm width, the 6302ZZ bearing is widely used across various industries for its durability and ability to handle moderate radial and axial loads efficiently. Its metal shield design helps prevent the ingress of particles into the bearing, reducing friction and wear while ensuring smooth operation under load. Constructed with a pressed steel cage, the 6302ZZ bearing maintains proper ball guidance and load distribution, supported by its normal radial internal clearance. Lubricated with grease, it operates effectively within a temperature range typically spanning from -30°C to +120°C, adapting well to diverse industrial and automotive environments.
