Double Row Cylindrical Roller Bearings NNUB4920-80 are a high-quality solution for a range of industrial applications. Made from durable materials and designed with precision engineering, these bearings are capable of withstanding heavy loads and high speeds. They are ideal for use in a variety of industries, including machine tools, paper mills, steel mills, and more.

Featuring a double-row design, these bearings are able to accommodate both radial and axial loads. This means that they are highly versatile and can be used in a range of different applications. Their cylindrical shape and high radial stiffness also make them less susceptible to deflection than other types of bearings, which helps to ensure smooth and reliable operation even under heavy loads.

The NNUB4920-80 model in particular has an 80mm bore diameter and is designed for medium to large-sized machines. It features precision-ground raceways and rollers, which ensures optimum load distribution and reduces wear. Additionally, the bearings feature a high-strength brass cage that provides superior durability and long life.

Double Row Cylindrical Roller Bearings NNUB4920-80 are also designed to be easy to install and maintain. They are pre-lubricated with grease, which helps to reduce friction and wear, and they can be easily re-lubricated as needed. This helps to extend the life of the bearings and ensure optimal performance over time.
