The SKF NAO series is a needle roller bearing that includes both an inner and an outer ring. It is built to handle significant radial forces where the available space is minimal. The needle design provides stiffness and load capacity, which makes it a common choice in machine tools, transmission systems and automotive parts. MR Industrial Accessories supplies this series as part of its bearing range.
Reading the NAO code is straightforward once you know the pattern. Take NAO 12X24X13: the first figure is the bore, 12 mm; the second is the outside diameter, 24 mm; and the third is the width, 13 mm. In the same way, NAO 40X55X17 has a bore of 40 mm, an outside diameter of 55 mm and a width of 17 mm. This system lets you match the bearing to your shaft and housing dimensions quickly.
These bearings appear in gearboxes, pumps, compressors, machine tools and power transmission equipment. Their compact cross-section suits arrangements where radial space is tight but high performance is still required. You will find them across automotive, metalworking and general machinery manufacturing.
When choosing a needle roller bearing, look at the radial load, the operating speed and the environment. During installation, use the correct tools to prevent damage to the needles and raceways, and check alignment. Apply the lubricant specified for the application. In dirty or contaminated conditions, add extra sealing protection. Proper mounting helps the bearing reach its expected service life.
For equivalents, SKF NAO series bearings can be replaced by products from other manufacturers that use the same dimensional designation, such as INA, NSK or NTN, provided tolerances and load ratings are compatible. Always confirm the technical data from each maker before substituting. At MR Industrial Accessories, we can help you review the options for your equipment.

Frequently asked questions
- What does the NAO designation mean in an SKF needle roller bearing?
- NAO identifies a needle roller bearing that has both an inner and an outer ring. The numbers that follow give the bore diameter, outside diameter and width, in that order, so you can identify the dimensions at a glance.
- In what applications is an NAO bearing recommended?
- It suits applications with high radial loads and limited space, such as gearboxes, pumps, compressors and machine tools. Its compact design allows high load capacity in a small envelope.
- How should I mount a needle roller bearing to avoid failures?
- Mount it carefully with the right tools and verify alignment. Lubricate correctly and protect it from contamination. If you have questions, contact us by WhatsApp and we will advise you.
