SKF NN series cylindrical roller bearings are built for high radial loads and considerable speeds. Their double-row configuration and sturdy construction suit demanding industrial equipment such as machine tool spindles, gearboxes and power transmission systems. MR Industrial Accessories LLC supplies this SKF line to customers throughout the United States and several Latin American countries.
The NN prefix denotes a double-row cylindrical roller bearing with a machined brass cage centered on the inner ring. The following digits give the size and dimensional series. A KTN9 suffix points to a window-type brass cage; /SPW33 indicates a fiberglass-reinforced polyamide cage plus a retaining ring groove. Reading these codes helps you confirm the design features of each variant before ordering.
Typical uses include main spindles on grinding machines, milling machines and CNC lathes, along with industrial gearboxes, high-flow pumps and compressors. In metalworking, automotive and machine tool operations, these bearings support precision and durability where unplanned downtime is costly.
Choosing the correct bearing depends on radial load, rotational speed and the operating environment. Installation calls for strict cleanliness, accurate alignment and proper lubrication, whether grease or oil. Check sealing and internal clearance against the specified tolerances. Poor mounting can lead to vibration, overheating and early failure, so follow the manufacturer's recommended mounting practices.
For equivalents, SKF NN series bearings can be interchanged with products from other makers that use the same dimensional and design designation, such as FAG, NSK or NTN, provided the tolerances and clearance are respected. Always verify the complete part number and particular features, because small differences in cage or sealing can affect performance. Consult a specialist before substituting one brand for another.

Frequently asked questions
- What does the KTN9 suffix mean on an NN bearing?
- KTN9 indicates a machined, window-type brass cage centered on the inner ring. This cage design is used in high-speed and high-load precision applications.
- What is the difference between NN and N bearings?
- NN bearings have two rows of cylindrical rollers, giving them higher radial load capacity and greater rigidity. N bearings have a single row and are used in lower-load applications.
- How do you mount an SKF NN cylindrical roller bearing?
- Mounting requires cleanliness, alignment and proper lubrication. Use the recommended mounting tools and verify internal clearance. Follow the manufacturer's instructions and consult a specialist for best results.
