Nachi 6903-2Z (61903-2Z) deep groove ball bearing

Product detailed description

The Nachi 6903 ZZECM (61903-2Z) ball bearing is a precision-engineered component designed for various industrial applications where high reliability and accuracy are required. This bearing is manufactured by the Japanese company Nachi, known for its quality and innovation in the field of rolling bearings.

The bearing has an inner diameter (d) of 17 mm, an outer diameter (D) of 30 mm and a width (B) of 7 mm, which makes it a compact solution suitable for applications with limited space. Its design is based on a single-row arrangement of balls, which ensures an optimal balance between load capacity and low friction.

The material composition of the bearing includes standard steel for rolling bearings, which provides excellent wear resistance and long service life. The bearing is equipped with a pressed steel cage, which ensures stable guidance of the balls and minimizes the risk of their mutual contact.

The Nachi 6903 ZZECM bearing is equipped with double-sided sheet metal covers that protect the internal components from contamination with dust and dirt, thereby extending its service life. These covers also allow operation in a temperature range from -40 °C to +120 °C, which increases its versatility in various working conditions.

The accuracy of the bearing is in accordance with class P0/PN, respectively. ABEC 1, which guarantees reliable and smooth operation in applications where accuracy is critical. The bearing has normal radial clearance with narrow tolerances, which contributes to its stable performance.

Thanks to its technical characteristics, the Nachi 6903 ZZECM bearing is an ideal choice for applications where high precision, reliability and resistance to adverse conditions are required. Its low weight, only 0.02 kg, simplifies handling and installation in various devices.
