How to read NSK NU217E
- NU 2Series
- Cylindrical roller bearings, NU 2 series. For the same bore, each series has a different outside diameter and width.
- 17Bore
- 85 mm bore: 17 × 5.
- ESuffix
- NSK suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 217 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The NSK NU217E bearing has a 85 mm bore, a 150 mm outside diameter and a 28 mm width (85 x 150 x 28 mm).

The NSK NU E series cylindrical roller bearing is a separable bearing with a flanged outer ring and a flangeless inner ring, designed to withstand high radial loads and allow axial displacement of the shaft within the housing. It is used in equipment where thermal expansion or assembly requires freedom of longitudinal movement, such as gearboxes, pumps, fans and machine tools.
The designation of these bearings is read in parts: NU indicates that the inner ring has no flanges and that the assembly is separable; the number that follows is the dimension code, and the final E indicates the execution with a polyamide cage and higher load capacity than the previous series. That is why references such as NU220E, NU317E or NU2220E coexist: the size changes, not the logic of the series.
In Argentine industry they appear in gearboxes and gear units, centrifugal pumps, industrial fans, compressors, machine tools and transmission equipment. Since the inner ring has no flanges, the shaft can move axially and the bearing accommodates thermal expansion without generating parasitic loads. It is a common choice in assemblies where the other support already fixes the axial position.
To select correctly, take into account the radial load, speed, cage type and sealing of the assembly. During mounting, the inner ring fits on the shaft and the outer ring in the housing; it is advisable to verify alignment between supports and lubricate with the amount and type of grease or oil corresponding to the operating conditions. Misaligned mounting or insufficient lubrication shortens service life.
Cross-brand equivalences are handled by dimension code and execution type: an NU from another company's E series can be interchanged if diameter, width and flange configuration match. When a customer brings an unidentified part or another brand's code, at MR Accesorios Industriales we cross-reference it and tell you the compatible reference so that the quote is correct.

Frequently Asked Questions
- What are the dimensions of the NSK NU217E bearing?
- The NSK NU217E bearing has a 85 mm bore, a 150 mm outside diameter and a 28 mm width (85 x 150 x 28 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 217.
- What does the E mean in an NU E bearing?
- The E identifies the execution with a polyamide cage and higher load capacity within the NU series. The preceding number defines the bearing dimensions. To confirm the exact reference, send us the complete code via WhatsApp.
- How do I choose between an NU and another type of cylindrical roller bearing?
- It depends on whether the shaft needs to move axially and which support fixes the position. The NU, with no flanges on the inner ring, allows that displacement. Tell us the application and the load so we can guide you.
- Can I replace an NU from another brand with an NSK one?
- Yes, when the dimensions and flange configuration match. Equivalence is defined by the dimension code and the execution. Send us the original part code and we will quote the corresponding NSK reference.
