Decoding SKF 6224 M/C3
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 24Bore
- Bore 120 mm (24 × 5).
- M/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6224 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6224 M/C3 measures 120 mm across the bore and 215 mm across the outside diameter; its width is 40 mm (120 x 215 x 40 mm).

SKF deep groove ball bearings in the 60 series are thin-section, single-row components built with a machined brass cage. They handle radial loads and combined loads where axial space is tight, and they run smoothly at moderate to high speeds in electric motors, pumps, fans and gearboxes.
Reading the part number is straightforward. The first two digits give the dimension series, here the 60 series. The following two digits are the bore code: in 6014, the 14 corresponds to a 70 mm bore. Suffixes M/C3 and M/C4 tell you the cage is machined brass and the radial internal clearance is above normal, which suits interference fits or elevated operating temperatures.
These bearings appear in low and medium power electric motors, centrifugal pumps, industrial fans, screw compressors, machine tools and speed reducers. Because they tolerate moderate radial and axial loads, they work well in belt or gear drives that need precise, low-maintenance shaft support.
When selecting a bearing, look at radial and axial load, speed and the operating environment. Choose C3 or C4 clearance if the shaft fit is an interference fit or if operating temperature goes above 100 °C. Mount with the correct tools and never strike the balls directly. Grease or oil lubrication is acceptable, and shaft-to-housing alignment must be maintained to prevent extra loads.
For equivalences, SKF deep groove ball bearings interchange with other brands that use the same ISO designation, such as FAG, NSK or NTN, provided tolerances and internal clearance match. Always check the cage suffix and clearance, because not every brand offers the same options. When replacing, compare the main dimensions and operating conditions first.

Frequently asked questions
- SKF 6224 M/C3 bearing: what are its dimensions?
- SKF 6224 M/C3 measures 120 mm across the bore and 215 mm across the outside diameter; its width is 40 mm (120 x 215 x 40 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6224.
- What does the M/C3 suffix mean on an SKF bearing?
- M stands for a machined brass cage, which handles vibration and high temperatures well. C3 means radial internal clearance is greater than normal, which is recommended for interference fits or when the shaft and housing run at different temperatures.
- How do I decide between C3 and C4 clearance?
- C4 clearance is larger than C3 and is used when temperatures are higher or fits are tighter. For typical conditions, C3 is usually enough. Share your equipment data and we can advise.
- Can I use another brand instead of SKF?
- Yes, if the ISO designation matches in dimensions and clearance. FAG, NSK and NTN offer equivalents. Check the cage type and internal clearance to confirm interchangeability.
