Decoding FAG 23180-BEA-XL-K-2RSR-MB1
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 80Bore
- Bore 400 mm (80 × 5).
- BEA-XL-K-2RSR-MB1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23180 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 23180-BEA-XL-K-2RSR-MB1 measures 400 mm across the bore and 650 mm across the outside diameter; its width is 200 mm (400 x 650 x 200 mm).

When shafts flex or alignment is imperfect, FAG 231 BEA series spherical roller bearings keep equipment running. Their two rows of spherical rollers and spherical outer raceway handle heavy radial loads and axial loads in both directions while tolerating angular misalignment. MR Industrial Accessories supplies these bearings to maintenance and purchasing teams throughout the United States and Latin America.
The part number follows a logical structure. The first digits give the dimension series: 23160, 23164, 23168, 23172, 23176 and 23180 all belong to the 231 family. The letter suffixes then define the internal design and features: BEA for cage and internal geometry, XL for the lower-friction generation, K for a tapered bore, 2RSR for seals on both sides, and MB1 for a brass cage guided by the inner ring. Always read the complete code before ordering.
Typical applications include heavy gearboxes and gear units, mills, vibrating screens, paper machines, induced draft fans, and mining and cement equipment. They also appear in conveyors and presses where shafts experience bending. The self-aligning capability simplifies assemblies with separate housings or structures that deform under load.
Selection starts with the radial and axial loads the equipment must withstand, the rotation speed and the shaft diameter. Decide between a cylindrical or tapered bore: the K version mounts on a tapered shaft or adapter sleeve and permits radial clearance adjustment. The 2RSR seal suits dusty, wet or vapor-rich environments; for open assemblies with oil lubrication, a version without seals can be used. Follow the specified alignment, lubrication and mounting clearance.
Spherical roller bearings are often compared across brands by series number and suffixes, but each manufacturer uses its own nomenclature for cage, sealing and internal design. A FAG code cannot be replaced by another brand's number alone: dimensions, clearance, bore and cage type must be verified. If you have the original equipment code, send it and we will cross-reference it.
To request a quote, send the full code on WhatsApp or by email, for example 23160-BEA-XL-K-2RSR-MB1, or the designation shown on the drawing or old bearing. MR Industrial Accessories replies promptly with the corresponding reference. If the equipment requires a variant not listed, send the model and we will look for it.

Frequently asked questions
- FAG 23180-BEA-XL-K-2RSR-MB1 bearing: what are its dimensions?
- FAG 23180-BEA-XL-K-2RSR-MB1 measures 400 mm across the bore and 650 mm across the outside diameter; its width is 200 mm (400 x 650 x 200 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23180.
- What does the K suffix mean in the bearing code?
- K indicates a tapered bore, typically 1:12. It is mounted on a tapered shaft or with an adapter sleeve and allows radial clearance to be adjusted when the bearing is locked in place. If your shaft is cylindrical, choose the variant without K.
- What is the purpose of the 2RSR seal?
- The 2RSR suffix means the bearing is sealed on both sides. It protects against dust, moisture and lubricant loss, making it useful in dirty or washdown environments. In oil-lubricated assemblies, it may not be necessary.
- How do I request a quote for a FAG bearing?
- Send us the full code shown on the bearing or on the equipment drawing via WhatsApp or email, for example 23164-BEA-XL-K-2RSR-MB1. With that data we verify the designation and reply promptly.
