For applications where radial space is limited but loads are significant, the SKF NKI series needle roller bearing is a practical choice. It uses machined inner and outer rings along with a steel cage, and its single-row design handles high radial loads within a very small envelope. MR Industrial Accessories supplies this line as part of its SKF bearing range.
The part number itself tells you the key dimensions. In the NKI prefix, the letters identify a single-row needle roller bearing with machined inner and outer rings. A slash separates the bore diameter from the overall width, both in millimeters. So NKI 9/12 means a 9 mm bore and a 12 mm width, while NKI 10/16 indicates a 10 mm bore and a 16 mm width. Reading the code this way lets you confirm the size before ordering.
These bearings appear in machine tools, pumps, compressors, electric motors, power transmission equipment and agricultural machinery. Their ability to take heavy radial loads in confined spaces makes them suitable for gearboxes, pulleys, rollers and cam systems. You will also find them in the automotive, textile, food and packaging industries, where precision and durability matter.
When selecting an NKI bearing, consider the radial load, the rotational speed and the operating environment. Shaft and housing alignment is critical because these bearings do not tolerate misalignment well. For sealing, assess the level of contamination: in dirty conditions, add supplementary seals. Grease or oil lubrication is possible, with the choice depending on temperature and speed. Use proper mounting tools to avoid damaging the rings.
SKF NKI series bearings can be interchanged with equivalent products from other manufacturers that share the same dimensional designation, such as INA, NSK or NTN, as long as you check tolerances and load ratings. Always review the technical data from each maker to confirm compatibility. MR Industrial Accessories can help you evaluate the best option for your application.

Frequently asked questions
- What does the NKI designation indicate in a needle roller bearing?
- NKI identifies a single-row needle roller bearing with machined inner and outer rings. The numbers after the slash give the bore diameter and overall width in millimeters.
- Where are NKI bearings typically used?
- They are common in machine tools, pumps, compressors, electric motors, transmissions and agricultural machinery, especially where radial capacity is needed in tight spaces.
- How should these bearings be lubricated and mounted?
- Either grease or oil can be used, selected according to temperature and speed. Mounting requires alignment and suitable tools to prevent ring damage. In contaminated areas, adding seals is advised.
