Product Overview: The NN 3020 Double Row Cylindrical Roller Bearing
The NN 3020 is a high-precision, double row cylindrical roller bearing with dimensions of 100x150x37mm. As a key component in our NN 3000 Series, this bearing is engineered for applications demanding high rigidity and exceptional radial load-carrying capacity. Part of the broader Cylindrical Roller Bearings category, its design features two rows of cylindrical rollers, which provides excellent stability and support for rotating shafts, particularly in high-speed and precision-critical machinery. The NN 3020 is a non-locating bearing, allowing for axial displacement between the shaft and housing to accommodate thermal expansion.
As a specialist supplier of industrial components, we ensure our NN 3020 bearings meet stringent industry standards for performance and reliability. Its robust construction and precision engineering make it a preferred choice for machine tool spindles, industrial gearboxes, and other heavy-duty equipment where accuracy and durability are paramount.
Key Features of the NN 3020 Bearing
