NSK 6804 ZZ deep groove ball bearing

Product detailed description

NSK 6804 ZZ is a deep groove ball bearing designed for a wide range of industrial applications. This bearing is manufactured by the renowned Japanese manufacturer NSK, which is known for its precision and high quality of production. The bearing has an inner diameter of 20 mm, an outer diameter of 32 mm and a width of 7 mm, which makes it compact and suitable for applications with limited space.

The bearing design includes single-row balls made of rolling steel, which are placed in a pressed steel cage. This cage ensures proper ball guidance and minimizes friction, contributing to a long bearing life. The bearing is equipped with double-sided sheet metal covers (ZZ), which protect the internal components from dirt and moisture, while not requiring additional lubrication throughout the entire service life.

NSK 6804 ZZ is made of standard steel for rolling bearings, which guarantees high wear resistance and strength at operating temperatures ranging from -20 °C to +120 °C. The bearing has normal radial clearance, which means that it is suitable for common applications where no special clearance requirements are made.

The running accuracy of the bearing is in class P0/PN, which corresponds to the American ABEC 1 standard. This level of accuracy is sufficient for most standard applications where extremely precise tolerances are not required. The bearing is not insulated against the passage of electric current, which is important to consider when using it in electrical equipment.

With a total weight of 0.03 kg, the NSK 6804 ZZ is light and easy to handle, which makes its installation and maintenance easier. It is ideal for use in a variety of industries, including automotive, mechanical engineering, and electrical equipment manufacturing, where reliability and long service life are required.
