Nachi 6904-2NSECM (61904-2RS) deep groove ball bearing
Code: 654984Product detailed description
The Nachi 6904-2NSECM (61904-2RS) ball bearing is a precision component designed for a wide range of applications where high accuracy and reliability are required. This bearing belongs to the category of deep groove ball bearings, which are known for their ability to carry both axial and radial loads.The bearing has an inner diameter (d) of 20 mm, an outer diameter (D) of 37 mm and a width (B) of 9 mm. It is made of high-quality standard steel for rolling bearings, which guarantees its long service life and wear resistance. The inner hole is of a cylindrical profile, which allows easy assembly on the shaft.
The bearing is equipped with a double-sided rubber contact seal, which provides excellent protection against dust and moisture, thereby extending the service life of the bearing and reducing the need for maintenance. The seal also helps maintain the optimal amount of lubricant inside the bearing.
The bearing cage is pressed from steel, which ensures strength and stability during operation. The bearing is designed as a single-row, which means that it contains one row of balls, which minimizes friction and increases efficiency.
The operating temperature range of the bearing is from -20 °C to +130 °C, which allows it to be used in various climatic conditions. The bearing meets the P0/PN accuracy standard, respectively. ABEC 1, which guarantees high running accuracy. The internal radial clearance is normal, but with narrow tolerances, which contributes to precise fit and stability at high speeds.
The total weight of the bearing is 0.04 kg, which makes it light and suitable for applications where the weight of the components is critical. The bearing is not insulated against the passage of electrical current, which is important to consider when using it in electrical equipment. This component is ideal for industrial applications where reliability and long-term operation without frequent service interventions are required.
