NUP Type Cylindrical Roller Bearings

Description

NUP cylindrical roller bearings have ribs on both sides of the outer ring, a (fixed) single rib on one side of the inner ring, and a detachable flat ring on the other side. They can withstand a certain amount of bidirectional axial load. This type of structural bearing can limit the displacement of the shaft relative to the bearing seat in both axial directions. Therefore, it is suitable for use as a fixed-end bearing.

Application

NUP bearings can bear bidirectional axial loads, so they can be used in situations where bidirectional axial positioning is required. They are often used in high-precision machine tools, precision instruments and other equipment that have high requirements for axial positioning.
