Decoding SKF NU 2217 ECML/C3
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 17Bore
- Bore 85 mm (17 × 5).
- ECML/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2217 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 2217 ECML/C3 measures 85 mm across the bore and 150 mm across the outside diameter; its width is 36 mm (85 x 150 x 36 mm).

For machinery that must carry heavy radial loads at speed, the SKF NU ECML series of cylindrical roller bearings is a common choice. These bearings provide the rigidity and precision needed in industrial equipment, electric motors and power transmission systems. MR Industrial Accessories LLC supplies this line to customers throughout the United States and Latin America.
Reading the part number helps you select the right bearing. The NU prefix means the inner ring has no flanges, so the shaft and housing can shift axially relative to each other. The following digits, such as 208, 210 or 214, identify the size and dimension series. ECML denotes an optimized geometry with a machined brass window cage. A suffix like C3 or C4 calls out radial internal clearance above normal. A complete code, for example NU 214 ECML/C4, ties these features together for a given application.
You will find NU ECML bearings in gearboxes, centrifugal pumps, industrial fans, machine tools and conveying systems. Industries that rely on them include metallurgy, cement, food processing and petrochemicals. Their capacity for high radial loads and their stiffness suit gear transmissions and other mechanically demanding duties.
Selection depends on three main factors: radial load, rotational speed and the operating environment. Choose C3 or C4 clearance based on working temperature and mounting fit. Lubrication can be grease or oil, depending on speed and temperature. During mounting, align the bearing precisely and avoid impacts that could damage rollers or raceways. For sealing, consider the level of external contamination; in dirty conditions, add extra seals.
Interchangeability is possible with other brands that use the same dimensional and clearance designation. Still, tolerances and internal design can differ between manufacturers, so confirm compatibility with our technical team before substituting.

Frequently asked questions
- SKF NU 2217 ECML/C3 bearing: what are its dimensions?
- SKF NU 2217 ECML/C3 measures 85 mm across the bore and 150 mm across the outside diameter; its width is 36 mm (85 x 150 x 36 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2217.
- What does the ECML suffix mean in an NU bearing?
- ECML indicates an optimized design with higher load capacity and a machined brass window cage, which improves performance and durability in demanding applications.
- How do I choose between C3 and C4 clearance?
- C3 clearance suits normal conditions with moderate temperatures. C4 is selected when higher temperatures or tighter fits are expected, as these reduce internal clearance during operation.
- Can I replace an SKF NU bearing with another brand?
- Yes, as long as the dimensional designation and internal clearance match. However, verify tolerances and internal design, as they can influence performance. Consult us to confirm the equivalence.
