Types of cylindrical roller bearings with a full gear on the inner ring:
N series:
The inner ring has a edge and allows axial movement in one direction.
NU series:
The inner ring is without an edge and allows axial movement in both directions.
NJ series:
The inner ring has a edge and allows axial movement in one direction.
NUP series:
The inner ring has a fixed edge and a movable edge, allowing axial movement in one direction.
Applications:
These types of roller bearings are used in a wide range of applications, including industrial machinery, gearboxes, motors and pumps. For example, in gearboxes, these bearings are used to accommodate radial and axial loads caused by shaft rotation. In motors, these bearings are used to accommodate radial loads caused by rotor rotation.
