Decoding SKF NU 314 ECP
- NU 3Series
- Cylindrical roller bearings, NU 3 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- ECPSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 314 ECP 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 NU..ECP line covers single-row cylindrical roller bearings built for substantial radial loads and elevated speeds. Rollers make line contact with the raceways, spreading the load across a wider area, which supports high capacity and stiffness. Typical installations include industrial machinery, electric motors and power transmission equipment.
In the NU configuration, the inner ring carries no flanges while the outer ring has two. That arrangement permits the shaft to shift axially relative to the housing. The digits after NU define the size and dimension series. The ECP suffix points to an optimized internal design that uses a high-strength polyamide cage, intended for high speeds and moderate operating temperatures.
These bearings appear in many sectors, such as metallurgy, cement, food processing and automotive. Gearboxes, pumps, fans, compressors and machine tools are common hosts. Heavy radial capacity and rigidity suit duties where precision and dependable operation matter, including harsh conditions.
Selection calls for a review of radial load, speed and the surrounding environment. During mounting, align shaft and housing carefully so no extra stress is introduced. Lubrication should match the speed and temperature; a quality grease or oil works. Sealing depends on contamination risk, so add seals or shields in dirty locations. Confirm internal clearance for the application.
For equivalences, SKF NU..ECP bearings can be exchanged with other brands that use the same dimensional and design designation. Tolerances and internal clearance can differ between makers, so check the technical data before substituting.

Frequently asked questions
- SKF NU 314 ECP bearing: what are its dimensions?
- SKF NU 314 ECP 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 NU 314.
- What does the ECP suffix indicate?
- It denotes an optimized design with a high-strength polyamide cage, suited to high speeds and moderate temperatures. Other internal refinements may also be included depending on the manufacturer.
- How does the NU series differ from other cylindrical roller series?
- The NU type has an inner ring without flanges, which allows axial displacement. Series such as NJ or NUP use different flange arrangements to limit axial movement in one or both directions.
- How do I select the right NU bearing?
- Consider radial load, speed, temperature and environmental conditions. Check shaft diameter and housing dimensions. Share your equipment data with us for guidance.
