Decoding SKF NU 2214 ECM/CNRVQ335
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- ECM/CNRVQ335Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2214 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 2214 ECM/CNRVQ335 measures 70 mm across the bore and 125 mm across the outside diameter; its width is 31 mm (70 x 125 x 31 mm).

Cylindrical roller bearings in the SKF NU ECM line are built for radial duty and higher running speeds. The NU arrangement lets the shaft move axially inside the bearing, and the ECM build pairs an optimized internal geometry with a machined brass cage. This makes the series a common pick for gearboxes, pumps, compressors and similar equipment where radial stiffness matters.
Reading the designation helps you match a replacement. NU means the outer ring carries two ribs while the inner ring has none, so axial movement is possible. E marks an optimized design, and M identifies the machined brass cage. The suffix CNRVQ covers tolerances and noise criteria: CN is normal radial clearance, and RVQ refers to quality and noise requirements. A complete example is NU 2214 ECM/CNRVQ335.
Typical installations include gearboxes, industrial pumps, compressors, high-flow fans and machine tools. The series also appears in metallurgical, cement, food and mining equipment, and in power transmission and continuous conveying systems. It handles vibration and moderate temperatures well, which is why it turns up in demanding plants.
When selecting, check radial load, rotational speed and the surrounding conditions. Dust or moisture calls for sealed or shielded variants. CN clearance is the standard choice, but higher temperatures may call for more clearance. Mount with accurate alignment between housing and shaft, and lubricate according to speed and load. The brass cage provides strength and guidance.
Bearings from different makers can often be swapped when the main dimensions, tolerances and clearance line up, since the boundary dimensions are standardized. Suffix codes differ between brands, so verify the full part number and specifications before substituting.

Frequently asked questions
- SKF NU 2214 ECM/CNRVQ335 bearing: what are its dimensions?
- SKF NU 2214 ECM/CNRVQ335 measures 70 mm across the bore and 125 mm across the outside diameter; its width is 31 mm (70 x 125 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2214.
- What does ECM indicate on an SKF bearing?
- ECM points to an optimized design with a machined brass cage. It is a sturdy configuration for demanding duty. Send us the full part number if you are unsure.
- How does an NU bearing differ from an NJ?
- NU has two ribs on the outer ring and none on the inner ring, so axial displacement is allowed. NJ has one rib on the inner ring, which limits movement in one direction. Your need for axial freedom decides the choice.
- Can I substitute another brand for an SKF bearing?
- Check that dimensions, tolerances and radial clearance match. Suffix designations vary between manufacturers. We can help you validate the equivalence using the exact part number.
