ZEN 688-2Z (628/8-2Z) deep groove ball bearing

Product detailed description

ZEN 688-2Z (628/8-2Z) ball bearing is a precision designed component designed for various applications where reliable support of rotational movements is required. This bearing belongs to the category of deep groove ball bearings, which are known for their ability to carry both radial and axial loads in both directions.

The bearing has an inner diameter (d) of 8 mm, an outer diameter (D) of 16 mm and a width (B) of 5 mm, which makes it compact and suitable for applications with limited space. It is made of high-quality standard steel for rolling bearings, which ensures long service life and wear resistance. The rolling elements are also made of this steel, which contributes to the overall robustness and reliability of the bearing.

The bearing is equipped with a double-sided sheet metal seal, which provides protection against dust and other contaminants, thus extending its service life and reducing the need for maintenance. The steel cage, which is pressed, ensures the correct arrangement of the balls and contributes to the smooth running of the bearing.

The ZEN 688-2Z bearing operates in a temperature range from -20 °C to +120 °C, which allows it to be used in a variety of environments. It has normal radial clearance, which is a standard setting for most applications, and the running accuracy is in the P0/PN class, or ABEC 1, which corresponds to the basic level of accuracy for normal use.

This component is a single-row bearing with a cylindrical bore, without a flange or groove on the outer ring. It is not equipped with insulation against the passage of electrical current, which is important to consider in applications where electrical connections may occur. With a weight of 0.004 kg, this bearing is lightweight, which is advantageous for applications where weight minimization is important.

ZEN is known for its quality and reliability, making the 688-2Z bearing a suitable choice for a wide range of industrial and mechanical applications.
