When radial space is tight, the NTN BK series needle roller bearing offers a compact solution. This open-type bearing uses a steel cage and mounts directly onto the shaft, so no inner ring is needed. That simplifies assembly and keeps weight down. It handles radial loads well in confined areas. MR supplies these bearings to maintenance and purchasing teams across the United States and Latin America. We can help you confirm the correct part number for your equipment.

Reading the BK part number is straightforward. The letters BK mean a needle roller bearing with a cage, open type. The digits that follow give the dimensions in millimeters: the first pair is the bore diameter, the second pair is the outside diameter. For example, BK0306T2 has a bore of 3 mm and an outside diameter of 6 mm. BK0408T2 measures 4 mm bore by 8 mm outside diameter. BK0609T2 has a 6 mm bore and a 9 mm outside diameter. The T2 suffix indicates a glass fiber reinforced polyamide cage, which is suitable for moderate operating temperatures.

These bearings appear in many industrial settings. You will find them in machine tools, transmission equipment, pumps, compressors, and electric motors. The automotive sector uses them in gearboxes, camshafts, and steering mechanisms. Packaging, textile, and agricultural machinery also rely on them where precision and durability matter. Their ability to carry high radial loads in tight spaces makes them a common choice for these applications.

Selecting the right bearing starts with the shaft diameter, the radial load, and the lubrication conditions. The BK series has no integral seals, so if dust or moisture is present, add a radial shaft seal or another external sealing method. Lubrication can be grease or oil, but you must maintain a proper lubricant film. Use the correct tools during mounting to avoid damaging the needles and cage. Check shaft and housing alignment to get the most from the bearing.

For equivalents, NTN BK series bearings can be interchanged with other brands that use the same dimensional nomenclature, such as SKF, FAG, NSK, or KOYO. However, tolerances and cage types can differ between manufacturers, so always verify. If you are replacing an existing bearing, the safest approach is to send us the complete part number or the shaft and housing dimensions. We will identify a compatible option for you.
