Decoding NSK NU210EW
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- EWSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 210 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK NU210EW measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm).

The NSK NU series cylindrical roller bearing handles high radial loads and speeds, thanks to its cylindrical rollers and steel cage. It is commonly found in industrial machinery, gearboxes, pumps, and power transmission equipment. MR Industrial Accessories supplies this series to customers across the United States and Latin America. To get a quote, just send the part number or the dimensions you need.
The NU code tells you how the bearing is built. The letters NU mean the inner ring has no flanges, so the ring and shaft can move axially relative to each other. The number that follows—205, 206, 207, for example—sets the size and load capacity. An EW suffix indicates a stamped steel window cage made for high speeds and loads. Part numbers like NU205EW, NU206EW, and NU210EW follow this pattern.
These bearings show up in food processing, cement, steel, and petrochemical plants. They are used in gearboxes, conveyor belts, mills, centrifugal pumps, and machine tools. Because they take high radial loads and tolerate minor misalignment, they suit rotating equipment that runs continuously. MR Industrial Accessories offers this series to industrial buyers in the US and several Latin American countries.
Selection depends on radial load, rotation speed, and operating conditions. The NU series allows axial displacement in both directions, so it works well as a free-end support. Check shaft and housing alignment, and make sure lubrication is right: grease for low speeds, oil for high speeds. Use the proper tools during mounting to avoid damaging rollers and raceways.
NSK NU series bearings interchange with other brands that use the same dimensional nomenclature, such as SKF, FAG, or NTN. Always confirm tolerances and internal clearance for your application. If you have a part number from another brand or an unidentified part, we can suggest a compatible equivalent. That interchangeability simplifies replacements and helps reduce downtime.

Frequently asked questions
- NSK NU210EW bearing: what are its dimensions?
- NSK NU210EW measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 210.
- What does the EW suffix mean on NU bearings?
- The EW suffix means the bearing has a stamped steel window cage. This cage is designed for high speeds and loads, 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 takes axial loads in one direction. Your choice depends on whether 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. You can also send a photo or a part number from another brand to identify the equivalent.
