Decoding FAG 22228-E1A-XL-K-2RSR-M
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 28Bore
- Bore 140 mm (28 × 5).
- E1A-XL-K-2RSR-MSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22228 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

The FAG 22228-E1A-XL-K-2RSR-M is a double-row spherical roller bearing. Its self-aligning design lets the shaft and housing work with some angular misalignment, and the tapered bore allows mounting on an adapter or withdrawal sleeve. This makes it a practical choice for conveyors, gearboxes, mills and other process equipment where mounting is not perfect or the shaft flexes under load.
The part number breaks down into sections. The 222 series indicates a medium-section spherical roller bearing. E1A refers to an optimized internal design. XL means long-life design. K stands for tapered bore. 2RSR indicates contact seals on both sides. M denotes a solid brass cage. Reading each block correctly helps you order the exact replacement.
Typical applications include belt conveyors, screens, mills, mixers, high-flow pumps and speed reducers. They also appear in mining, cement, food and aggregate processing, where shafts deflect or housings are not perfectly aligned. The self-aligning feature helps protect the rollers and supports service life in demanding installations.
When selecting a bearing, consider radial and axial loads, speed and the operating environment. The 2RSR contact seals block dust and moisture but add friction; for very high speeds, an open bearing with proper lubrication may be better. The K tapered bore mounts on an adapter or withdrawal sleeve, which simplifies setting internal clearance. Check alignment, lubrication and tightening according to the equipment manual.
For cross-brand equivalents, compare the complete designation: type, dimension series, seals, cage and bore. The same base number can differ in internal clearance or heat treatment between manufacturers. Do not swap a sealed bearing for an open one without checking contamination risks. If unsure, send the code engraved on the component and the main dimensions.

Frequently asked questions
- FAG 22228-E1A-XL-K-2RSR-M bearing: what are its dimensions?
- FAG 22228-E1A-XL-K-2RSR-M measures 140 mm across the bore and 250 mm across the outside diameter; its width is 68 mm (140 x 250 x 68 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22228.
- What does the K suffix mean in the designation?
- K indicates a tapered bore, usually with a 1:12 taper. This design mounts on adapter or withdrawal sleeves and allows internal clearance to be adjusted during mounting, which is useful on long shafts or hard-to-reach equipment.
- When is a 2RSR sealed bearing preferable?
- 2RSR seals protect against dust, water and particles, making them ideal in dirty or humid environments. At very high speeds, however, they generate more friction and heat; an open design with controlled lubrication may be better. Assess the environment and speed.
- How do I request a quote on WhatsApp?
- Write to us with the complete code engraved on the bearing, for example 22228-E1A-XL-K-2RSR-M, or with the main dimensions and the type of equipment. That way we can identify the exact variant and reply shortly.
