Decoding FAG 2222-K-M-C3
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 22Bore
- Bore 110 mm (22 × 5).
- K-M-C3Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2222 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 2222-K-M-C3 measures 110 mm across the bore and 200 mm across the outside diameter; its width is 53 mm (110 x 200 x 53 mm).

When shafts flex or alignment between supports is not exact, a self-aligning ball bearing keeps the application running. This FAG design uses two rows of balls and a spherical outer raceway, so the inner ring can tilt and compensate for misalignment relative to the housing. It handles radial and axial loads in both directions, making it a practical choice for fans, pumps, conveyors and agricultural equipment.
The part number is built in blocks. The base number gives series and size: 1219 is series 12, 1315 is series 13, and the two series differ in dimensions and load capacity. A K means tapered bore, for mounting on a tapered shaft or with an adapter sleeve. An M means a machined solid brass cage, intended for higher demands. C3 indicates internal clearance greater than normal, used with tight fits or elevated temperatures. So 1219-K-M-C3 tells you series, size, bore type, cage and clearance.
These bearings suit equipment where the shaft may flex or shift during operation: centrifugal fans, centrifugal pumps, belt conveyors, vibrating screens, mixers, and agricultural machinery such as seeders and harvesters. They also appear in large electric motors and gearboxes running under moderate loads. The self-aligning action lowers the risk of premature failure when the base is not perfectly rigid or when mounting does not achieve exact alignment between supports.
Selection depends on the radial and axial load the equipment must withstand, the rotation speed and the operating environment. A K bore requires an adapter sleeve or tapered shaft, and mounting must be done with the correct internal clearance, here C3. Grease or oil lubrication can be used, depending on the application and speed. Check initial alignment and clearance after mounting; excessive tightness can damage balls and raceways. The M brass cage adds strength and helps dissipate heat.
Self-aligning ball bearings are made to international standards, so brands can often be interchanged while keeping similar dimensions and capacities. However, cage, clearance and tolerance variants exist between manufacturers. For a quote, include the complete part number with all suffixes. If you cannot find the exact number, send us the model or the shaft and housing dimensions and we will help identify a suitable option.

Frequently asked questions
- FAG 2222-K-M-C3 bearing: what are its dimensions?
- FAG 2222-K-M-C3 measures 110 mm across the bore and 200 mm across the outside diameter; its width is 53 mm (110 x 200 x 53 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2222.
- What does the K suffix mean on this FAG bearing?
- K indicates a tapered bore. It allows mounting on a tapered shaft or with an adapter sleeve, which simplifies adjustment and disassembly in applications that need secure fastening.
- When should C3 clearance be used?
- C3 is greater than normal clearance. It is used with tight fits, temperature differences between inner and outer rings, or to allow for expansion and avoid preloading the bearing.
- How do I request a quote?
- Send the complete part number, for example 1219-K-M-C3, by WhatsApp or email. If you only have shaft and housing dimensions, include those and we will suggest the right option.
