SKF NN series cylindrical roller bearings are built for high radial loads and elevated speeds. Their double-row design and self-aligning behavior suit demanding machinery, and MR Industrial Accessories LLC supplies them within its SKF bearing range for customers across the United States, Canada, Mexico and South America.
Reading the code helps you order correctly. NN identifies a double-row cylindrical roller bearing with a cylindrical bore. The digits that follow set the size and dimension series. Suffixes carry internal design and tolerance information: KTN is generally tied to a polyamide cage, while SPW33 points to a special execution with restricted tolerances and, in some cases, a retaining ring groove. Check the SKF catalog for the exact specification behind each code.
These bearings fit positions where radial load dominates and rigidity and precision matter. Machine tool spindles, gearboxes, industrial pumps, compressors and power transmission equipment are typical hosts. Metalworking, food processing, oil and power generation operations rely on them, and their capacity for high speeds makes them a fit for critical rotating equipment.
Selection starts with radial load, rotation speed and the surrounding environment. Mounting has to hold precise alignment so extra stresses do not appear. Lubrication matters just as much: match the lubricant to temperature and speed. Sealing follows the level of external contamination, so choose seals or protectors where dirt is present. Keep the internal clearance the manufacturer recommends.
For replacements, SKF NN series bearings may have equivalents from other makers, yet dimensions and load capacities must be checked first. Direct interchange is not automatic, since tolerances and internal design can differ. Speak with a specialist before substituting a bearing, above all in critical applications, and MR Industrial Accessories LLC can point you to the right option.

Frequently asked questions
- What does the KTN suffix indicate on an SKF bearing?
- KTN generally indicates a polyamide cage, which lowers weight and supports performance at high speeds. Confirm the exact characteristics in the SKF catalog for each code.
- Can SKF NN bearings be replaced by other brands?
- Equivalent parts may exist from other manufacturers, but they are not necessarily interchangeable. Dimensions and capacities can differ, so consult a specialist before replacing an SKF bearing with another brand.
- How should an SKF NN bearing be lubricated?
- Lubrication depends on speed, load and temperature. Follow the manufacturer's instructions and use quality lubricants. For critical applications, ask our team to help select the right lubricant.
