Design variables:
Types N and NU: These types allow for axial displacement between the inner and outer rings, adapting to axial expansion caused by temperature changes. This is useful in applications with large thermal variations.
Type NJ: Provides axial load capability in one direction, making it suitable for applications requiring limited axial support.
NUP type: Provides axial load support in both directions and axial positioning in applications requiring light axial guidance.

Structure and components:
Separable: Single-row cylindrical roller bearings are usually separable, which means that the inner and outer rings can be removed independently. This design simplifies installation, inspection and maintenance.
Roller profile: Rollers are precision-machined with slightly raised tops to prevent edge stress, enhance load distribution, reduce wear and extend bearing life.

Application program:
Motors: Ideal for high-speed motors because they are able to reduce friction while supporting significant radial loads.
Gearboxes and transmissions: Often used for gearboxes with high radial loads because they provide stability under heavy and fluctuating loads.
Pumps and compressor shafts: Common in applications that require reliability, low friction and high durability under constant radial loads.

Advantages:
High radial load capacity: These bearings can support higher radial loads compared to ball bearings due to the linear contact of the cylindrical rollers.
Low friction: They have low rolling friction, making them efficient for high-speed applications.
Thermal expansion adjustment: Some designs (N and NU) allow for axial movement that helps accommodate thermal expansion without putting pressure on the bearing.
