The NTN NK series needle roller bearing is a single-row radial bearing without an inner ring, mounted directly on the shaft. Its compact design and high radial load capacity make it ideal for applications where space is limited and rigidity is required. It is used in transmissions, pumps, compressors and textile machinery, among others. At MR Accesorios Industriales we quote it according to the size you need.
The NK series designation is read as follows: the letters NK identify a needle roller bearing without an inner ring; the first number after the slash indicates the bore diameter (in millimeters) and the second, the total width. For example, NK5/10T2 has a 5 mm bore and 10 mm width; NK8/12T2, 8 mm bore and 12 mm width. The suffix T2 indicates a polyamide cage of specific design. With this data you can quickly identify the reference you need.
These bearings are used in industries such as automotive, metallurgical, textile and food. In Argentina, they are commonly found in gearboxes, water pumps, compressors, machine tools and transmission equipment. Thanks to their low profile, they allow reducing the size of the assembly without sacrificing load capacity. MR Accesorios Industriales sells them for replacement and new projects throughout the country.
To select the correct bearing, take into account the shaft diameter and length, the radial load and the lubrication conditions. Since it has no inner ring, the raceway is ground directly on the shaft, so adequate hardness and roughness are recommended. Assembly must ensure precise alignment to avoid lateral forces. Lubrication can be grease or oil, depending on the speed and working temperature.
NTN NK series needle roller bearings are interchangeable with those of other brands that follow the same dimensional nomenclature. When looking for a replacement, verify that the main dimensions (bore diameter, outer diameter and width) and the cage type match. If you have doubts, our technical team can advise you to find the right equivalence. It is always advisable to consult specialists before replacing a bearing.

Frequently Asked Questions
- What does the T2 suffix mean in an NK bearing?
- The T2 suffix indicates that the bearing has a polyamide cage of specific design. This cage guides the rollers and allows high speeds with low friction. It is important to verify that the replacement has the same cage to maintain performance.
- How do I choose the right NK bearing for my application?
- You need to know the shaft diameter, the available width and the radial loads. Also consider the speed and lubrication. With that data, we can quote you the exact reference. If you are not sure, consult us and we will advise you.
- Are NTN NK bearings interchangeable with other brands?
- Yes, as long as the main dimensions and cage type match. The NK series follows international dimensional standards, which facilitates interchangeability. If you have another brand's code, we can indicate the NTN equivalence.
