Product Overview: The NN 3038 Double Row Cylindrical Roller Bearing
The NN 3038 is a high-precision, double row cylindrical roller bearing engineered for applications demanding exceptional rigidity and high radial load capacity. With dimensions of 190x290x75mm, this bearing is a key component in our NN 3000 Series, part of the broader Cylindrical Roller Bearings category. The NN 3038 features two rows of cylindrical rollers, providing superior radial support and minimizing deformation under heavy loads. Its design makes it an ideal choice for machine tool spindles and other precision machinery where accuracy is paramount. The inner ring of this bearing is separable, which simplifies the mounting and dismounting process, allowing for an interference fit with both the shaft and housing.
