[tab name='More Information']
The NJ type cylindrical roller bearing is a specific type of roller bearing commonly used in applications where high radial load capacity and moderate axial load capacity are required. It belongs to the family of cylindrical roller bearings, known for their ability to support heavy radial loads and moderate axial loads.

The NJ designation stands for "locating unit with a separable inner ring," indicating that this bearing design incorporates a separable inner ring that can be mounted independently from the outer ring. This feature allows for easier installation, disassembly, and maintenance of the bearing.

NJ type cylindrical roller bearings consist of an inner ring (single flange on one side), an outer ring, cylindrical rollers, and a cage assembly. The cylindrical rollers are arranged in parallel between the inner and outer rings and guided by the cage, which maintains their proper spacing and prevents excessive friction between the rollers.

NJ type cylindrical roller bearings are commonly used in applications such as electric motors, pumps, gearboxes, and machine tools, where high radial loads and moderate axial loads are present. The separable design facilitates easy mounting and dismounting, simplifying maintenance procedures, and reducing downtime.

These bearings offer high radial load carrying capacity and can accommodate moderate axial loads in both directions. They are designed to operate at high speeds with low friction and provide reliable and smooth operation.

In summary, the NJ type cylindrical roller bearing provides excellent radial load capacity, moderate axial load capacity, and axial guidance in both directions. Its separable design enhances ease of installation and maintenance, making it a versatile choice for applications that require precise axial positioning and support heavy radial loads.
