Nachi 6905-2NSECM (61905-2RS) deep groove ball bearing

Product detailed description

The Nachi 6905-2NSECM (61905-2RS) deep groove ball bearing is a single-row deep groove ball bearing designed for a wide range of industrial applications. It features compact dimensions with an inner diameter of 25 mm, an outer diameter of 42 mm and a width of 9 mm. The bearing is made of high-quality standard steel for rolling bearings, which guarantees its long service life and reliability in operation.

The bearing is equipped with a double-sided rubber contact seal that provides protection against dust and moisture, thereby extending the service life of the bearing and reducing the need for maintenance. The seal also allows operation in a temperature range from -20 °C to +120 °C, and can withstand temperatures up to +130 °C for short periods.

The bearing design includes a pressed steel cage that ensures stable mounting of the rolling elements and reduces friction. The bearing has normal radial clearance with narrow tolerances, which contributes to the accuracy of the P0/PN class or ABEC 1.

The outer ring of the bearing is without a flange or groove, and the hole has a cylindrical profile, which allows easy assembly and disassembly in various applications. The bearing is not equipped with insulation against the passage of electric current, therefore it is suitable for mechanical applications where electrical insulation is not required.

The total weight of the bearing is 0.05 kg, which contributes to its easy handling and installation. The manufacturer of this bearing is the renowned Japanese company Nachi, which is known for its precision and quality in the field of rolling bearing production.
