NF Type Cylindrical Roller Bearings

Description

The NF cylindrical roller bearing has ribs on one side of its outer ring and ribs on both sides of its inner ring. It is designed to withstand a certain amount of unidirectional axial load. This type of structure is suitable for use as a one-way axial positioning bearing.

Application

Due to its high radial load capacity, NF bearings are often used in equipment that bears large loads, such as rolling mills and heavy machinery.
