When a machine tool spindle has to hold accuracy at speed, the bearing choice often lands on a double row cylindrical roller design. The NTN NN series is built for exactly that duty: two rows of rollers running in a rigid, precision assembly that takes radial load without giving up rotational smoothness. MR Industrial Accessories quotes these bearings by part number, and can also help you work out the right size or a cross-reference if you send the details.
Reading the code tells you most of what you need. The NN prefix marks a double row cylindrical roller bearing; the digits that follow give bore size and dimension series. Take NN3013HST6: the bore is 65 mm. NN3020HST6 steps up to 100 mm. The HST6 suffix points to a high-precision, high-speed execution that uses a synthetic cage and tighter tolerances than a standard bearing.
You will find these bearings in the main spindles of lathes, milling machines, grinders and machining centers, as well as in boring machines, precision grinders and measuring equipment. The common thread is rotational accuracy under load. Metalworking, automotive and machine tool operations all rely on them where runout has to stay small and the spindle has to stay stiff.
Selection starts with shaft diameter, radial load and the top speed the spindle will see. Fitting calls for clean conditions, correct alignment and proper lubrication, usually a high-quality oil or grease. The polyamide cage and double row layout support high speeds, but internal clearance and fitting tolerances still have to be respected.
NTN NN series bearings interchange with other makers that use the same dimensional nomenclature. If you have a part number from another brand, that is enough for us to identify the equivalent and quote the exact item. What matters for interchange is the main dimensions and the execution type, not the commercial number on the box.

Frequently asked questions
- What does the HST6 suffix mean on an NN bearing?
- HST6 identifies a high-precision, high-speed version with a synthetic cage and reduced tolerances, often used in machine tool spindles. Send the full part number and we will quote that specification.
- How do I choose between an NN bearing and a single row one?
- The NN double row series carries more radial load and adds rigidity, which suits spindles. A single row may be enough when loads are moderate and space is tight. Share your application data and we will advise.
- Can I replace an NN bearing from another brand with an NTN one?
- Yes, when the main dimensions and execution type match. Interchangeability rests on the dimensional standard. Give us the original part number and we will confirm the NTN equivalent and quote it.
