- 05Bore
- 25 mm bore: 05 × 5.
- EWSuffix
- NSK suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 305 is the standard (ISO) basic designation: it defines the type, the series and the bore.

The NSK NU series cylindrical roller bearing is a high radial capacity component, designed to withstand heavy loads and considerable speeds. Its construction with cylindrical rollers and a steel cage allows precise operation in demanding applications. It is used in industrial machinery, gearboxes, pumps and power transmission equipment. At MR Accesorios Industriales we quote it according to the part number or size you need.
The NU series designation is interpreted as follows: the letters NU indicate that the inner ring has no flanges, which allows relative axial displacement between ring and shaft. The number that follows (for example, 205, 206, 207) indicates the size and load capacity. The EW suffix identifies a stamped steel window cage, optimized for high speeds and loads. Examples such as NU205EW, NU206EW and NU210EW show this nomenclature. Learn more about this series and its applications.
These bearings are used in industries in Argentina such as food, cement, steel and petrochemical. They are present in gearboxes, conveyor belts, mills, centrifugal pumps and machine tools. Their ability to withstand high radial loads and minimal misalignment makes them suitable for continuously operating rotating equipment. MR Accesorios Industriales sells this series for the Argentine industrial market.
To select the right bearing, take into account the radial load, the rotation speed and the environmental conditions. The NU series allows axial displacement in both directions, so it is used as a free-end support. Check the alignment of the shaft and the housing, and ensure adequate lubrication: grease for low speeds or oil for high speeds. Mounting must be carried out with appropriate tools to avoid damage to the rollers and raceways.
NSK NU series bearings are interchangeable with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN. However, always verify the tolerances and internal clearance according to the application. If you have the part number of another brand or an unidentified part, we can tell you the compatible equivalent. Interchangeability makes replacement easier and reduces downtime.

Frequently Asked Questions
- What are the dimensions of the NSK NU305EW bearing?
- The NSK NU305EW bearing has a 25 mm bore, a 62 mm outside diameter and a 17 mm width (25 x 62 x 17 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 305.
- What does the EW suffix mean on NU bearings?
- The EW suffix indicates that the bearing has a stamped steel window cage, designed to withstand high speeds and loads. This cage guides the rollers precisely and allows better lubricant flow.
- How do I choose between an NU and an NJ bearing?
- The NU series has an inner ring without flanges and allows axial displacement. The NJ series has a flange on the inner ring that allows axial loads in one direction. The choice depends on whether or not you need axial freedom.
- What dimensions should I provide to request a quote for an NU bearing?
- Provide the complete part number (for example, NU205EW) or the bore, outer diameter and width dimensions. You can also send a photo of the part or the part number of another brand to identify the equivalent.
