Decoding FAG 23156-BE-XL-2RSR
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 56Bore
- Bore 280 mm (56 × 5).
- BE-XL-2RSRSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23156 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 23156-BE-XL-2RSR measures 280 mm across the bore and 460 mm across the outside diameter; its width is 146 mm (280 x 460 x 146 mm).

For equipment that must keep running despite shaft deflection or mounting misalignment, FAG spherical roller bearings are a common choice. Their double-row design handles radial loads and axial loads in both directions, while the spherical outer ring allows the inner ring and rollers to self-align. MR Industrial Accessories supplies this line and can help you confirm the correct execution for your application.
The part number tells you most of what you need to know before ordering. Take 23140-BE-XL-2RSR: 23140 is the series and size, BE means a brass cage with cylindrical bore, XL refers to the optimized design of the family, and 2RSR means rubber seals on both sides. Other sizes in the same series, such as 23144-BE-XL-2RSR and 23156-BE-XL-2RSR, share those features and differ mainly in dimensions. Reading these suffixes correctly is essential to avoid a wrong replacement.
These bearings appear in crushing, grinding, mixing and conveying equipment, as well as in cement mills, vibrating screens, food-industry machines and aggregate processing plants. They are also found in large gearboxes, presses and industrial fans. Because they tolerate shaft deflection, they suit assemblies where perfect alignment is difficult to maintain, which is typical in machines exposed to vibration or impact.
Selection depends on radial and axial load, rotation speed and the environment. The 2RSR version with rubber seals keeps out dust and moisture, but it can reduce the maximum permissible speed; in a clean setting where higher speed is needed, an open bearing may be the better option. During mounting, check the initial alignment and use the right tools so the seals and raceways are not damaged. Follow the manufacturer's lubrication specification and renew it according to your maintenance plan.
When replacing a bearing, people often compare designations across brands. Spherical roller bearings from different manufacturers can be interchangeable if the main dimensions, internal clearance and sealing type match. Suffixes, however, are not always equivalent from one brand to another. The reliable approach is to request a quote with the complete code, or send the housing and shaft measurements, and let us help you find the right equivalent among the brands we supply.

Frequently asked questions
- FAG 23156-BE-XL-2RSR bearing: what are its dimensions?
- FAG 23156-BE-XL-2RSR measures 280 mm across the bore and 460 mm across the outside diameter; its width is 146 mm (280 x 460 x 146 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23156.
- What does the 2RSR suffix mean on a FAG bearing?
- The 2RSR suffix means the bearing has rubber seals on both sides. This keeps dust, water and contaminants out of the raceways and rollers, and helps retain lubrication. It is a good choice for dirty or humid environments, though it can lower the permissible limiting speed.
- How do I know if a spherical roller bearing is interchangeable with another brand?
- Interchangeability depends on matching the bore, outer diameter and width, plus the cage type, internal clearance and sealing. Suffix codes can differ between manufacturers, so each case should be checked. Send us the original code and we will advise you on the equivalent.
- What care does the mounting of a spherical roller bearing require?
- Mount it with suitable tools and avoid striking the seals or rollers. Check the alignment of shaft and housing, and make sure lubrication is correct. If the bearing has seals, take care not to damage them during installation. Careful mounting extends the service life of the component.
