Decoding NSK NU2215ET M, T7
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- ET M, T7Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2215 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK NU2215ET M, T7 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 31 mm (75 x 130 x 31 mm).

For equipment that runs under constant radial load, the NSK NU ET M series cylindrical roller bearing is a common choice. Its cylindrical rolling elements and machined brass cage support demanding duty in gearboxes, pumps, fans and other power transmission drives. MR Industrial Accessories LLC supplies this series and quotes by part number, so tell us the size your application calls for.
Reading the code helps you order correctly. NU means the outer ring carries the flanges while the inner ring has none, so the shaft can move axially inside the bearing. ET identifies the machined brass cage, and M marks an internal modification. Two frequently requested examples are NU2215ET M and NU2315ET M, where 22 and 23 are the series. A T7 suffix points to a special tolerance. If any of this is unclear, our team can walk you through it.
Typical installations include speed reducers, gearboxes, centrifugal pumps, industrial fans, machine tools, conveyors and mills. Plants in the food, cement, steel and oil sectors rely on this bearing family for drives that see heavy radial load at considerable speed. Because the design allows axial displacement, it also suits arrangements where the shaft expands with temperature.
Selection comes down to a few inputs: radial load, rotation speed and the environment around the bearing. Open or side-plate versions cover different levels of contamination. Grease or oil lubrication depends on temperature and speed. During mounting, alignment and internal clearance both need attention. The ET M brass cage holds up well in severe service.
Equivalent cylindrical roller bearings from other manufacturers may be substituted when dimensions and tolerances line up, but confirm the full part number and technical data before you swap. Our team can review possible equivalents with you. To get a quote, send the complete part number, for example NU2215ET M, T7, by WhatsApp or email and we will reply promptly.

Frequently asked questions
- NSK NU2215ET M, T7 bearing: what are its dimensions?
- NSK NU2215ET M, T7 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 31 mm (75 x 130 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2215.
- What does NU ET M mean in an NSK bearing part number?
- NU tells you the outer ring has flanges and the inner ring does not, which permits axial displacement. ET is the machined brass cage, and M is an internal modification. Together they give the bearing high radial load capacity and strength.
- How do I pick the right cylindrical roller bearing for my equipment?
- Start with radial load, speed, temperature and contamination. Then decide between open and side-plate sealing and between grease and oil lubrication. The ET M brass cage suits severe conditions. Send us your equipment part number and we will help you choose.
- Where are NU ET M bearings used?
- They appear in gearboxes, pumps, fans, machine tools and power transmission equipment, as well as conveyors and mills. Their ability to handle heavy radial loads at considerable speed fits the food, cement, steel and oil industries.
