NTN NN series bearings are double row cylindrical roller bearings built to handle high radial loads with high rotational precision. They suit machine tool spindles, gearboxes and equipment where rigidity and rotational accuracy matter. MR Industrial Accessories supplies this line as part of its bearing range for customers in the United States and several Latin American countries.

Reading the designation helps you specify the right part. The letters NN identify a double row cylindrical roller bearing, and the number that follows gives the size within the series. A final letter K means the bore is tapered, so the bearing can be mounted with an interference fit on a tapered shaft or with an adapter sleeve. That combination of double row and tapered bore is common where high radial rigidity and good concentricity are required.

These bearings show up in grinding and milling machine spindles, machining heads, speed reducers and transmission equipment that carries significant radial loads. You will also find them in process pumps, compressors and textile machinery, where rotational precision and load capacity affect how long the equipment lasts.

When selecting a bearing, consider the radial load it will carry, the rotational speed and the lubrication method you plan to use. The tapered bore of the NN series makes mounting with a controlled fit easier, but you still need to check the concentricity of the shaft and the housing. Grease or oil can be used depending on the application; oil is common in high-speed spindles. Shaft-to-housing alignment is key to avoiding extra stresses.

For a replacement from another brand, compare the complete designation: series, size number and K suffix. Interchange between manufacturers is based on those dimensional and functional characteristics, not on an isolated code. So when you ask for an alternative, give the exact code from the part or the drawing, and we will point you to the compatible option.

To request a quote for any bearing in the NN series, send the complete code via WhatsApp or email, or send the measurements and characteristics you need. If you cannot find the exact variant, send the model anyway and we will help you sort it out.
