Decoding SKF NUP 234 ECM
- NUP 2Series
- Cylindrical roller bearings, NUP 2 series. Series differ in outside diameter and width even when the bore is the same.
- 34Bore
- Bore 170 mm (34 × 5).
- ECMSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 234 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For industrial applications that demand high radial load capacity and precise shaft guidance, SKF NUP ECM cylindrical roller bearings are a proven choice. This series is designed to handle combined loads and maintain rigidity in gearboxes, pumps, and transmission equipment. MR Industrial Accessories LLC supplies these bearings to maintenance and purchasing professionals across the United States, Canada, Mexico, and South America.
The NUP ECM designation provides key information. The prefix NUP identifies a cylindrical roller bearing with a fixed flange on the inner ring and a loose flange on the outer ring, allowing axial displacement in one direction. The number following the prefix indicates the bore size code. For instance, NUP 228 ECM and NUP 328 ECM have different bore diameters. The ECM suffix is part of the series marking.
These bearings are suited for demanding environments such as metal production, cement plants, mining operations, and food processing. Typical installations include gearboxes, centrifugal pumps, industrial fans, machine tools, and power transmission systems. Their cylindrical roller design ensures stable operation under high speed and heavy load.
When selecting a bearing, evaluate the radial and axial loads, operating speed, and ambient temperature. Proper mounting requires appropriate tools and adherence to alignment and lubrication practices for cylindrical roller bearings. Correct lubrication and sealing are critical to maximize service life.
For cross-brand interchange, compare dimensions and load ratings. SKF NUP ECM bearings can be replaced by products from other manufacturers that meet the same dimensional and design specifications. Always verify compatibility before substitution.
