Single row cylindrical roller bearings are available in several basic designs that differ from each other in number and arrangement of their flanges, the most important design variants are shown below.

N type bearings features two integral flanges on the inner ring and outer ring without flanges.

NU type bearings features two integral flanges on the outer ring and inner ring without flanges, N and NU type bearings belong to the Non-locating bearings, they are not able to accommodate any axial loads.

NJ type bearings features two integral flanges on the outer ring and one integral flange on the inner ring, this allows them to accommodate axial loads in one direction only.

NUP type bearings have two integral flanges on the outer ring, one integral flange on the inner ting and a loose rib, so it is locating bearing and can accept axial loads in either direction.

NJ type bearings used in conjunction with thrust collars can build a locating bearing, which can accept axial loads in either direction.
DHK single row cylindrical roller bearings have the rolling elements with modified outer diameter and crowning inner ring raceway, which minimize edge loading stresses between the rollers and raceway.

For applications operating under normal conditions the misalignment must not exceed 4 angular minutes.

For applications where higher misalignment may occur, DHK also produce single row cylindrical roller bearings with special crowned inner ring raceways (suffix B) to enable higher misalignments during operation.
DHK single row cylindrical roller bearings are available with all kinds material and design variants of cage upon request.

The most important materials and design variants of DHK single row cylindrical roller bearing cages are shown below.

Reinforced polyamide cages:

TN normal design of polyamide cage features holding lips on both side of roller pocket.

TN1 These are the enforced design of TN type.

TN2 Features holding lips on one side of roller pockets.This make it can raise the wall thickness of the cage at no-holding lip side, and therefore raised the strength of the cages.

Pressed Steel Cage: JP, JP1

Solid brass cages

M (MA, MB): normal design, features cage cover and cage body, rivetted by the steel rivets.

M2 (MA2, MB2): features cage body with round rivetting heads on its self and cage cover.

M6(MA6, MB6): features cage body with square riveting heads on its self and cage cover.

DHK single row cylindrical roller bearings are produced to normal tolerance class (PN) as standard.

DHK also can provide these bearings with closer tolerance class such as P6 and P5, tolerance.

Detailed tolerance values are listed in the chapter of tolerance of radial bearings, page 8.

1. The role of Series NU-Single Row Cylindrical Roller Bearings as floating bearings

As non-locating bearings, series NU-single row cylindrical roller bearings offer significant advantages in applications where axial movement or misalignment is inevitable. Unlike locating bearings, which restrict axial displacement, non-locating bearings provide flexibility, allowing components to adjust to varying operating conditions without undue stress or friction. This inherent ability to accommodate axial displacement makes NU-type bearings ideal for applications such as machine tool spindles, where thermal expansion or shaft deflection occurs during operation. By allowing slight movement along the axial plane, these bearings mitigate the risk of premature wear and damage to critical components, thereby enhancing system reliability and longevity. In addition to axial displacement, NU-type bearings excel in scenarios where shafts experience angular misalignment. Their design facilitates smooth rotation even in the presence of misalignment, ensuring consistent performance and reduced vibration levels. This capability is particularly valuable in applications such as conveyor systems and automotive drivetrains, where precise alignment is essential for optimal efficiency and productivity. The non-locating nature of series NU-single row cylindrical roller bearings affords engineers and designers greater flexibility in system design, enabling the creation of robust and reliable machinery capable of withstanding the rigors of real-world operating conditions.

2. Performance Characteristics and Operational Benefits

Series NU-single row cylindrical roller bearings stand out for their exceptional performance characteristics and operational benefits, making them indispensable components in various industrial applications.

a)Low Friction: NU-type bearings are engineered to minimize friction between rolling elements and raceways, thereby reducing energy consumption and heat generation. This characteristic is crucial for high-speed applications where efficiency is paramount, ensuring smooth and reliable operation over prolonged periods.

b)Reduced Noise Levels: The precision manufacturing processes employed in crafting NU-type bearings result in exceptionally smooth surfaces and tight tolerances, mitigating noise levels during operation. This is particularly beneficial in applications where noise reduction is essential for operator comfort, environmental considerations, or compliance with regulatory standards.

c)Enhanced Reliability: With their robust construction and superior material quality, NU-type bearings offer unmatched reliability even in demanding operating conditions. They excel in applications subjected to heavy loads, shock loads, and varying temperatures, maintaining consistent performance and longevity over extended service intervals.

d)Optimal Load Distribution: The design of NU-type bearings ensures uniform load distribution across the rolling elements, minimizing stress concentrations and extending bearing life. This feature is critical in applications where load variations are prevalent, ensuring smooth operation and preventing premature wear and failure.
