Decoding NTN NU2315EA
- NU 23Series
- Cylindrical roller bearings, NU 23 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- EASuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2315 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN NU2315EA measures 75 mm across the bore and 160 mm across the outside diameter; its width is 55 mm (75 x 160 x 55 mm).

NTN NU EA series cylindrical roller bearings are built for applications that demand high radial load capacity and high-speed operation. The design allows axial displacement between the inner and outer rings, which is useful in equipment where thermal expansion or shaft movement must be accommodated. Typical installations include gearboxes, pumps, compressors and other power transmission machinery. At MR Industrial Accessories LLC, we quote these bearings by the exact part number you provide.
The NU EA designation breaks down as follows: NU means the bearing has two ribs on the outer ring and none on the inner ring, permitting relative axial movement between the rings. The number after NU, such as in NU204EA, NU205EA or NU210EA, indicates the size and corresponds to the bore diameter. The EA suffix denotes an optimized roller and cage design that improves load capacity and performance. Understanding this code helps you specify the right part number when requesting a quote.
These bearings are used in demanding industrial environments such as metal processing, food production, cement plants and petrochemical facilities. They are commonly found in speed reducers, centrifugal pumps, screw compressors, industrial fans and machine tools. Their ability to handle high radial loads while running at high speeds makes them suitable for continuous-duty equipment where reliability and long service life are essential to avoid unplanned downtime.
When selecting a bearing, consider the radial load, operating speed and environmental conditions. Because the NU EA series allows axial displacement, it works well in applications that require freedom for thermal movement. Verify shaft and housing alignment, and choose the cage type and lubrication method based on the service conditions. Proper mounting with the correct tools is critical to prevent damage to rollers and raceways.
If you are replacing a bearing from another brand, equivalent cylindrical roller bearings may be interchangeable, but always confirm dimensions and tolerances. The NTN NU EA series can have counterparts in other manufacturers' catalogs, although suffixes may differ. Send us the part number you have, and we will help identify a compatible alternative.
To request a quote, contact us via WhatsApp or email with the complete part number or the required dimensions. Our team responds promptly and can suggest equivalents or assist with selection. We can also provide guidance on lubrication and mounting to help ensure optimal performance. Send your inquiry and we will get back to you quickly.

Frequently asked questions
- NTN NU2315EA bearing: what are its dimensions?
- NTN NU2315EA measures 75 mm across the bore and 160 mm across the outside diameter; its width is 55 mm (75 x 160 x 55 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2315.
- What does the EA suffix mean in NTN NU bearings?
- The EA suffix indicates an optimized roller and cage design that improves radial load capacity and performance. It is a common variant in the NTN NU series for demanding applications.
- How do I choose the right NU EA bearing for my equipment?
- You need to know the radial load, rotational speed and working conditions. Also check alignment and lubrication type. With that data, we can quote the exact part number you need.
- Can I replace a bearing from another brand with an NTN NU EA bearing?
- Yes, as long as dimensions and tolerances match. Cylindrical roller bearings with equivalent designations are usually interchangeable. Send us the original part number and we will identify a compatible alternative.
