- /800Bore
- Bore: 800 mm.
- B-MBSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
241/800 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

FAG spherical roller bearings handle radial and axial loads in both directions, and they tolerate shaft misalignment. Their two rows of rollers make them a common choice where heavy equipment runs under demanding conditions. MR Industrial Accessories LLC supplies this line and can help you match the right part number to your application.
The part code tells you a lot once you know how to read it. A series number comes first, then suffixes for design details. In large sizes, the digits after the slash often give the bore in millimeters, as in 230/1060-B-MB. The B suffix points to a machined brass cage, and MB confirms that cage style. Other series follow the same logic, so the code helps you identify the exact bearing your equipment needs.
These bearings show up in steel, cement, mining, paper, wind energy and material handling equipment, as well as in gearboxes, presses, mills and other large machines. The self-aligning feature suits long shafts that deflect under load, or assemblies where supports cannot be perfectly aligned. MR Industrial Accessories LLC supplies them for replacement and new projects across the United States and in several Latin American countries.
When selecting, look at radial and axial load, speed and shaft diameter. Check cage type and internal clearance: more clearance may be needed with interference fits or high temperatures. Lubrication should match the environment, with grease for normal conditions or oil for high-speed use. During mounting, align carefully and avoid direct blows on the rollers. Clean the seat and use the right tools to support service life.
For replacements, equivalent codes between manufacturers are common. Each brand may use its own suffixes for cage, clearance or heat treatment. The safest approach is to request a quote with the complete code from the bearing or with the main dimensions. MR Industrial Accessories LLC can help you find the FAG reference that fits your equipment and maintains the original performance.

Frequently asked questions
- FAG 241/800-B-MB bearing: what are its dimensions?
- FAG 241/800-B-MB measures 800 mm across the bore and 1280 mm across the outside diameter; its width is 475 mm (800 x 1280 x 475 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 241/800.
- What does the B-MB suffix mean in a FAG bearing?
- The B suffix usually indicates a design with a one-piece machined brass cage, and MB confirms that cage type. These details matter when you need to maintain the same performance in a replacement.
- How do I choose the right spherical roller bearing?
- Consider radial and axial load, speed, shaft diameter and environmental conditions. Also check internal clearance and lubrication type. With that data, we can advise you on the correct FAG part number.
- What applications do these bearings have?
- They are used in steel, cement, mining, paper, wind energy and material handling equipment, as well as in gearboxes, presses and mills. Their self-aligning capability makes them suitable for shafts that deflect under load.
