Decoding SKF NUP 314 ECNML/C3
- NUP 3Series
- Cylindrical roller bearings, NUP 3 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- ECNML/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NUP 314 ECNML/C3 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 35 mm (70 x 150 x 35 mm).

The SKF NUP ECNML/C is a cylindrical roller bearing built for shafts that carry heavy radial loads along with moderate thrust in either direction. Its machined brass cage is centered on the rollers, and the two-row roller arrangement keeps the shaft rigid under combined loads and tilting moments. Typical service includes gearboxes, pumps, fans, machine tools and mining equipment. MR Industrial Accessories supplies this series to maintenance and purchasing teams in the United States and Latin America.
Reading the code helps you order the right piece. NUP describes the ring configuration: two flanges on the inner ring, one on the outer ring, so the bearing locates the shaft axially in both directions. ECNML points to the high-capacity execution with a machined brass cage guided on the rollers. After the slash comes the radial clearance class, for instance C3 for extra clearance. Take NUP 314 ECNML/C3: 314 covers the bore diameter and the dimension series.
Selection starts with the loads the shaft will see, the speed of rotation and the surrounding conditions. Because these bearings tolerate very little misalignment, shaft and housing alignment has to be accurate before mounting. Grease or oil both work as lubricants, provided the viscosity suits the duty. Where dust, water or process contamination is present, add seals. Clearance class should follow the operating temperature and the fit chosen for the shaft and housing.
Cross-referencing is possible with bearings from other makers that share the same boundary dimensions and internal specifications. Check the full designation, not just the bore size: cage style, clearance and load rating all have to line up. Suffix meanings differ from one brand to another, so it pays to have the code reviewed before a substitution is made. Our team can compare your existing reference against the SKF NUP ECNML/C range.

Frequently asked questions
- SKF NUP 314 ECNML/C3 bearing: what are its dimensions?
- SKF NUP 314 ECNML/C3 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 35 mm (70 x 150 x 35 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NUP 314.
- What does ECNML tell me about this bearing?
- It identifies the high-capacity version with a machined brass cage guided on the rollers, which suits higher speeds and tougher operating conditions. The letter after the slash sets the radial clearance class, such as C3.
- How do I pick the radial clearance class?
- It follows from the temperature the bearing will run at and the fits used on the shaft and in the housing. Hot running conditions or tight fits usually call for more clearance, such as C3. Check the application data before deciding.
- Can a bearing from another maker be swapped in?
- Only if the boundary dimensions and internal specifications match. Compare the whole designation, including cage type and clearance, because suffixes are not interchangeable across brands. Send us the reference and we will check it against the SKF NUP ECNML/C series.
