Decoding FAG 22211-E1-XL-K
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 11Bore
- Bore 55 mm (11 × 5).
- E1-XL-KSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22211 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 22211-E1-XL-K measures 55 mm across the bore and 100 mm across the outside diameter; its width is 25 mm (55 x 100 x 25 mm).

FAG spherical roller bearings are double-row, self-aligning units built to carry heavy radial loads together with axial loads in either direction, even when the shaft is not perfectly aligned. The spherical outer raceway lets the bearing adjust itself, compensating for shaft deflection or mounting inaccuracies. You will find them in conveyors, mills, pumps and other process equipment where flexing or vibration occurs. MR Industrial Accessories supplies this line and can help you pick the right variant.
Reading the code is straightforward once you know the blocks. The base number gives the size, such as 21308, 21309 or 21310. The suffixes then describe performance features: an optimized roller and cage design, a high-performance surface treatment, or a tapered bore with a 1:12 taper for mounting on an adapter sleeve or a tapered shaft. A complete reference like 21308-E1-XL-K therefore combines size, improved design and taper. Knowing how to break down these codes makes quoting faster and reduces the risk of ordering the wrong replacement.
These bearings appear in belt conveyors, flour and mining mills, high-flow centrifugal pumps, industrial fans, paper machines and chemical process equipment. Gearboxes and gear units subject to shaft flexing are another common location. Because the bearing self-aligns, it suits assemblies where the supports are not perfectly aligned or where the shaft bends under load, as happens with long transmission shafts or overhung pulleys.
Selection depends on the radial and axial load, the rotational speed and the lubrication method. When the bore is tapered (suffix K), you mount the bearing on an adapter sleeve or directly on a tapered shaft, which makes it easier to set internal clearance. Check the sealing arrangement: these bearings come open or sealed depending on the environment. Choose grease or oil according to temperature and speed. Initial alignment is less critical thanks to the self-aligning design, but you should still verify residual clearance after mounting.
Bearings from different brands can be interchanged when the main dimensions, bore type and design details (cage, sealing, tolerance) match. The base number alone is not enough: compare the suffixes, since a tapered bore version does not replace a cylindrical one without the correct adapter sleeve. For a safe substitution, send the full part number and the operating conditions, and we will guide you to the right reference in the brand we carry.

Frequently asked questions
- FAG 22211-E1-XL-K bearing: what are its dimensions?
- FAG 22211-E1-XL-K measures 55 mm across the bore and 100 mm across the outside diameter; its width is 25 mm (55 x 100 x 25 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22211.
- What does the K suffix mean on a spherical roller bearing?
- K indicates a tapered bore with a 1:12 taper. This lets you mount the bearing on a tapered shaft or with an adapter sleeve, which simplifies setting internal clearance. If your shaft is cylindrical, choose the version without K or use the appropriate adapter sleeve.
- How can I tell if a bearing from another brand replaces a FAG one?
- Compare the main dimensions (bore, outside diameter and width), the bore type and the design suffixes. The base number alone is not enough: cage, sealing and tolerance must also match. Send us the full part number and we will help you verify the equivalent.
- What lubrication is recommended for these bearings?
- It depends on speed, temperature and environment. A high-quality grease covers many applications; at high speeds or elevated temperatures, oil may be necessary. Follow the manufacturer's recommendations and check the lubricant condition periodically.
