Product Overview: The NN 3028 High-Precision Cylindrical Roller Bearing
The NN 3028 is a high-performance, double-row cylindrical roller bearing, an integral part of our NN 3000 Series. With principal dimensions of 140x210x53mm, this bearing is engineered for applications demanding exceptional radial stiffness, high load-carrying capacity, and high-speed capabilities. Its design features two rows of cylindrical rollers, which provides a high degree of rigidity, making it an ideal choice for machine tool spindles and other precision rotating machinery where accuracy is paramount.
As a leading supplier of industrial components, we ensure our NN 3028 bearings meet stringent quality standards. The separable design, with an inner ring that can be mounted independently from the outer ring and roller assembly, simplifies both installation and maintenance procedures.
