The NSK NU EM T series is a single-row cylindrical roller bearing that handles high radial loads and speeds. Its inner ring, outer ring and roller assembly can be mounted separately, which simplifies equipment assembly and disassembly. Typical applications include gearboxes, pumps, electric motors and machine tools where radial rigidity and precision matter.

Decoding the part number helps you confirm the right bearing. The letters NU describe the flange arrangement: no flange on the inner ring and two flanges on the outer ring, so the bearing carries radial load only. The code EM indicates a machined brass cage and reinforced load capacity. The final T denotes an assembly variant. In examples such as NU215EM T, T7 and NU315EM T, T7, the 2 and 3 identify the dimension series, while 15 is the bore diameter. The T7 suffix is a tolerance or treatment variant defined by the complete part number.

These bearings are common in speed reducers, centrifugal pumps, industrial fans, medium and large electric motors, and machine tool spindles. They also appear in mining, cement and steelmaking equipment where radial loads are steady and shaft speed is sustained. Because the inner ring has no flanges, the shaft can move axially within the housing, making these bearings suitable for floating supports in gear trains and transmissions.

When selecting a bearing, check bore diameter, mounting dimensions and load type. The machined brass cage of the EM design handles acceleration and shock better than a sheet metal cage. Proper mounting requires clean housing and shaft, correct fit and alignment between supports. Lubrication may be grease or oil depending on speed and operating temperature. In contaminated environments, consider external sealing or a bearing with shields, since the open NU series does not include seals.

Cylindrical roller bearings are interchangeable across manufacturers by dimensional designation: series, bore diameter and width. Cage, tolerance and clearance letters vary by brand, so equivalence should be confirmed using the complete part number, not just the size. If you have an unidentified part or another brand's number, MR Industrial Accessories can cross-reference it and provide the corresponding NSK reference. We can also evaluate variants with different clearance or sealing for your equipment.

MR Industrial Accessories supplies NSK bearings and a full line of bearings, housings and power transmission components. For NU215EM T, T7, NU315EM T, T7 or any other size in the series, send the part number via WhatsApp or email and we will quote promptly. If the bearing is already mounted and you lack the reference, provide the shaft and housing dimensions and we will identify the matching option.
