Decoding SKF 6311 M/C4VL0241
- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 11Bore
- Bore 55 mm (11 × 5).
- M/C4VL0241Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6311 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6311 M/C4VL0241 measures 55 mm across the bore and 120 mm across the outside diameter; its width is 29 mm (55 x 120 x 29 mm).

SKF deep groove ball bearings in the 62 and 63 series are single-row, deep-raceway components built to carry radial and axial loads in rotating equipment. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America, including versions with machined brass cages and specific internal clearances.
Reading the bearing code tells you what you are getting. In 6214 M/C3VL0241, the 62 is the medium section series and 14 is the bore diameter. The M stands for a machined brass cage, C3 for radial clearance above normal, and VL0241 for a special coating on the outer surface. In the 63 series the section is wider, and the C4 suffix calls for even greater clearance. These designations let you match the bearing to the duty.
Typical installations include electric motors, centrifugal pumps, fans, gearboxes, and conveyors in food processing, petrochemical, steel, and mining operations. Where humidity, dust, or corrosive agents are present, the 62 and 63 series with brass cage and VL0241 coating is often selected for added resistance and load dissipation.
Selection depends on radial and axial load, rotation speed, and the operating environment. Choose C3 or C4 internal clearance when fits are interference-type or when thermal gradients are expected. The machined brass cage resists fatigue and supports higher speeds. During mounting, keep shaft and housing alignment precise and use the correct tools to prevent damage. Apply the lubricant specified for the temperature and speed of the application.
SKF bearings interchange with other recognized brands that share the same standardized dimensions. For a replacement, confirm that the type, principal dimensions, and clearance and cage suffixes all match. Our team can suggest an equivalent that respects your equipment's original specifications.

Frequently asked questions
- SKF 6311 M/C4VL0241 bearing: what are its dimensions?
- SKF 6311 M/C4VL0241 measures 55 mm across the bore and 120 mm across the outside diameter; its width is 29 mm (55 x 120 x 29 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6311.
- What does the VL0241 suffix mean on an SKF bearing?
- VL0241 indicates a special coating on the outer surface of the outer ring. It improves corrosion resistance and electrical conductivity, which is useful in humid environments or where parasitic currents are a concern.
- When should I choose a C3 or C4 internal clearance?
- C3 or C4 clearance is advisable when the bearing runs at high temperatures, uses interference fits, or faces thermal deformation. The greater clearance helps prevent premature seizure and extends service life.
