The NSK NU EM T series cylindrical roller bearing is a single-row, separable bearing designed to withstand high radial loads and high speeds. The outer ring, inner ring and roller assembly are mounted separately, which simplifies assembly and disassembly of the equipment. It is used in gearboxes, pumps, electric motors and machine tools, where precision and radial rigidity are critical.

The series designation is read in blocks. The letters NU indicate the arrangement of the ring flanges: the inner ring has no flange and the outer ring has two, so the bearing only accepts radial load. The code EM identifies the machined brass cage design and the reinforced load capacity. The final T indicates an execution variant of the assembly. In the examples NU215EM T, T7 and NU315EM T, T7, the numbers 2 and 3 mark the dimension series and the 15 the bore diameter. The suffix T7 corresponds to a tolerance or treatment variant that is defined by the complete part number.

In Argentine industry these bearings appear in speed reducers, centrifugal pumps, industrial fans, medium and large electric motors, and machine tool spindles. They are also found in mining, cement and steelmaking equipment, where radial loads are constant and the shaft rotates at sustained speed. Because they have no flanges on the inner ring, they allow axial displacement of the shaft within the housing, which makes them suitable for floating supports in gear trains and transmissions.

To select the bearing, you must verify the bore diameter, the mounting dimensions and the type of load. The machined brass cage of the EM design tolerates accelerations and shocks better than a sheet metal cage. Mounting requires cleanliness of the housing and shaft, correct fit and alignment between both supports. Lubrication can be grease or oil depending on the speed and working temperature. In contaminated applications, it is advisable to evaluate external sealing or a bearing with shields, because the open NU series does not incorporate its own seals.

Cylindrical roller bearings are interchangeable between manufacturers by their dimensional designation: series, bore diameter and width. The cage, tolerance and clearance letters change with each brand, so the equivalence is confirmed with the complete part number and not only with the size. If the customer brings an unidentified part or another brand's part number, at MR Accesorios Industriales we cross-reference it and tell you the corresponding NSK reference. We can also evaluate variants with different clearance or sealing depending on the equipment.

MR Accesorios Industriales sells NSK bearings and the rest of the line of bearings, housings and power transmission. If you need the NU215EM T, T7, the NU315EM T, T7 or any other size in the series, send us the part number by WhatsApp and we'll quote it shortly. If the bearing is mounted on equipment and you don't have the reference at hand, send us the shaft and housing dimensions and we'll tell you the corresponding option.
