Decoding SKF NU 318 ECM/C3VL0241
- NU 3Series
- Cylindrical roller bearings, NU 3 series. Series differ in outside diameter and width even when the bore is the same.
- 18Bore
- Bore 90 mm (18 × 5).
- ECM/C3VL0241Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 318 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 318 ECM/C3VL0241 measures 90 mm across the bore and 190 mm across the outside diameter; its width is 43 mm (90 x 190 x 43 mm).

Cylindrical roller bearings in the SKF NU series are built for machinery that carries heavy radial loads at considerable speed. The cylindrical roller arrangement paired with a machined brass cage gives the bearing its stiffness and load capacity, which is why it shows up in machine tools, electric motors and transmission equipment where precision matters. MR Industrial Accessories LLC supplies this line to customers throughout the United States and Latin America.
Reading the code tells you most of what you need to know. Take NU 220 ECM/C3VL0241: NU means the inner ring carries no flanges, so the shaft can move axially inside the bearing. The 220 identifies the size and dimension series. ECM points to an optimized internal design with a machined brass cage. C3 signals internal radial clearance wider than standard, and VL0241 marks a special execution with an aluminum oxide coating for corrosion protection. Codes such as NU 318 ECM/C3VL0241 and NU 322 ECM/C3VL0241 follow the same pattern and differ only in size.
Steel mills, cement plants, mining operations and power generation are typical homes for these bearings, along with gearboxes, centrifugal pumps, industrial fans, machine tools and large electric motors. Heavy radial loads plus the coated execution make them a fit for harsh conditions, and power transmission equipment relies on them where precision and reliability are expected.
Selection comes down to three inputs: radial load, operating speed and the environment. Choose C3 when service heat is expected to close up the internal clearance. Choose the VL0241 execution where moisture or corrosive agents are present. At mounting, align the components carefully and apply the right lubricant, grease or oil depending on the application. The machined brass cage guides the rollers well and supports high speeds.
On interchangeability, an SKF NU series bearing can be swapped with another maker's product that follows the same dimensional and execution designation. Check internal clearance, cage type and special suffixes first, since these differ between manufacturers. Have a specialist confirm compatibility before you replace a bearing.

Frequently asked questions
- SKF NU 318 ECM/C3VL0241 bearing: what are its dimensions?
- SKF NU 318 ECM/C3VL0241 measures 90 mm across the bore and 190 mm across the outside diameter; its width is 43 mm (90 x 190 x 43 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 318.
- What does the C3 suffix mean on these bearings?
- C3 identifies internal radial clearance wider than standard. It suits applications where heat in service would otherwise reduce clearance, or where mounting tolerances call for more room. Match the clearance to the application before ordering.
- What is the VL0241 coating for?
- VL0241 is an aluminum oxide layer that shields the bearing from corrosion. It fits humid settings, water exposure or chemical agents, where resisting oxidation helps the bearing last longer in service.
- Can I replace an SKF bearing with another brand?
- Yes, provided dimensions, internal clearance and execution details match. Designations differ from one manufacturer to another, so verify the suffixes and have a specialist confirm interchangeability first.
