6204ZZ – Deep groove ball bearing

The 6204ZZ bearing is a variant of the 6204 series known for its metal shields on both sides (ZZ), providing 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 20 mm bore diameter, 47 mm outside diameter, and 14 mm width, it is widely used across industries for its durability and ability to handle moderate radial and axial loads efficiently. The bearing’s pressed steel cage maintains proper ball guidance under load, supported by its normal radial internal clearance, and it operates smoothly within a temperature range typically from -30°C to +120°C.
