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

When shaft deflection or mounting error keeps the shaft and housing out of line, a CARB bearing is often the practical answer. Its rollers are toroidally crowned, so the bearing carries radial load while allowing the inner ring to tilt relative to the outer ring. The result is a compact, self-aligning unit that suits assemblies where perfect alignment is not realistic. MR Industrial Accessories LLC supplies the SKF line to maintenance and purchasing teams in the United States and Latin America.
Reading a CARB designation is straightforward once you know the pattern. The leading C marks the series. The two digits that follow set the dimension series, so C 2217 sits in a medium section while C 2228 and C 2230 belong to the larger sizes. Suffixes then tell you about internal clearance: C3 and C4 both mean greater than normal radial clearance. A designation such as C 2220/C3 therefore pairs the 2220 series with C3 clearance.
These bearings turn up wherever radial load and misalignment arrive together: mill drives, conveyor belts, centrifugal pumps, industrial fans, cranes and mining equipment, plus paper and steel mill machinery where shafts deflect under load. Because the bearing absorbs angular misalignment, assemblies that are not perfectly aligned, including structures exposed to vibration, tend to run with less wear on the surrounding components.
Selection comes down to radial load, speed and internal clearance. Note that sealing is not standard in this series, so in dusty or damp surroundings plan on external protection. Lubrication matters just as much; follow the manufacturer's guidance for the temperature and speed of your application. At mounting, check the initial alignment even though the bearing compensates for misalignment, and make sure the fits on shaft and housing are correct. Using the right mounting tools protects the rollers and raceways.
On interchangeability: a CARB bearing can be matched with self-aligning roller bearings from other makers when dimensions and load capacity line up, but internal clearance and tolerances still need checking. No universal code table exists, since each manufacturer uses its own nomenclature. Compare principal dimensions and operating conditions instead of codes alone. MR Industrial Accessories LLC supplies SKF as one of the brands in its range.

Frequently asked questions
- SKF C 2217/C3 bearing: what are its dimensions?
- SKF C 2217/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 C 2217.
- What does C3 mean in a CARB bearing designation?
- C3 signals greater than normal internal radial clearance. It is specified when an interference fit would reduce running clearance, or when shaft and housing operate at different temperatures. C4 indicates even more clearance.
- Can a SKF CARB bearing be replaced by another brand?
- Another brand's self-aligning roller bearing can serve as an equivalent when dimensions and load capacity correspond. Because codes are not standardized across makers, verify the measurements and the internal clearance before substituting.
- What maintenance does a CARB bearing require?
- Correct lubrication for the temperature and speed of the application is the main point. Where dust or moisture is present, add external protection, since the series is not sealed as standard. Alignment at mounting and proper fits also affect how long the bearing lasts.
