Decoding SKF N 320 ECM/C3
- N 3Series
- Cylindrical roller bearings, N 3 series. Series differ in outside diameter and width even when the bore is the same.
- 20Bore
- Bore 100 mm (20 × 5).
- ECM/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
N 320 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF N 320 ECM/C3 measures 100 mm across the bore and 215 mm across the outside diameter; its width is 47 mm (100 x 215 x 47 mm).

Single-row radial cylindrical roller bearings from the SKF N ECM series use a machined brass cage that is centered on either the inner or the outer ring, depending on the design. They suit equipment that combines heavy radial loads with moderate to high speeds and needs a stiff, well-supported shaft. MR Industrial Accessories LLC supplies these bearings and helps you match the right suffix to your application.
Reading the code is the first step. Take N 222 ECM/C3, N 224 ECM/C3, N 319 ECM/C3, N 320 ECM/C3, N 322 ECM/C3 and N 324 ECM/C3: the leading N identifies the ring variant, the three digits give the size, EC points to a one-piece machined brass cage, M describes the cage design, and /C3 sets the internal radial clearance. Confirming each block keeps you from ordering a designation that will not fit the assembly.
These bearings show up in gear reducers and gearboxes, centrifugal pumps, industrial fans, machine tools, conveyors, and mining or cement equipment. Medium and large electric motors are another common home, since radial load dominates there and maintenance teams want predictable service intervals. MR Industrial Accessories LLC serves plants, maintenance workshops and assembly projects across the United States and in several Latin American countries.
Choosing the suffix starts with the clearance the equipment calls for. A /C3 value is wider than normal and makes sense with interference fits, thermal gradients or higher speeds. Also review the sealing or protection the environment demands, the lubrication plan, and the alignment between housing and shaft, because a cylindrical roller bearing performs best on a rigid, well-supported shaft. The ECM cage handles demanding loads and speeds, but it does not make careful mounting optional.
On interchangeability: bearings in this series can be swapped between manufacturers when dimensions, clearance and cage type line up, even though every brand marks the same characteristics with its own suffixes. The size number alone is not enough; compare the full execution. If anything is unclear, send the code engraved on the bearing or your shaft and housing dimensions and we will check it with you.

Frequently asked questions
- SKF N 320 ECM/C3 bearing: what are its dimensions?
- SKF N 320 ECM/C3 measures 100 mm across the bore and 215 mm across the outside diameter; its width is 47 mm (100 x 215 x 47 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation N 320.
- What does /C3 indicate in these bearings?
- /C3 marks an internal radial clearance wider than normal. It is selected when the assembly involves interference fits, temperature differences between shaft and housing, or high speeds, since those conditions reduce clearance during operation.
- Do I always need the ECM cage?
- The ECM cage is machined brass and fits applications with heavy radial loads and demanding speeds. With moderate loads or unusual temperature and lubrication conditions, review the complete execution before settling on a replacement.
- Can an SKF bearing from this series replace one from another brand?
- It can, provided dimensions, radial clearance and cage type match. Suffixes differ between manufacturers, so the size number alone proves nothing. Send the old code via WhatsApp or email and we will compare the full designation with you.
