Decoding FAG 23172-BEA-XL-2RSR-MB1
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 72Bore
- Bore 360 mm (72 × 5).
- BEA-XL-2RSR-MB1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23172 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 23172-BEA-XL-2RSR-MB1 measures 360 mm across the bore and 600 mm across the outside diameter; its width is 192 mm (360 x 600 x 192 mm).

A spherical roller bearing carries load on two rows of rollers running against a spherical outer raceway, so the shaft can flex and the housing can sit slightly out of line without the bearing losing capacity. The FAG BEA XL line covers sizes 23160, 23164, 23168, 23172, 23176 and 23180, and MR Industrial Accessories supplies it to plants running heavy duty equipment.
Reading the code in blocks makes selection faster. The first digits set the size: within 23160, 23164, 23168, 23172, 23176 and 23180, a higher number means a larger diameter. The letters that follow describe the execution, starting with BEA for the roller and cage design and XL for the higher capacity generation. A 2RSR marking means contact seals on both sides, and MB points to a solid brass cage guided by the inner ring. Any digits after that separate variants of the same execution.
These bearings turn up in heavy duty service: gear reducers and gearboxes, cement and mining mills, crushers, vibrating screens, paper machines, large industrial fans, steel mill equipment, overhead cranes, mineral conveyors and aggregate plants. Shafts in this kind of machinery bend under load and housings are rarely in perfect alignment, and the self aligning geometry keeps that misalignment from loading the supports.
Selection starts with radial and axial load, running speed, shaft diameter and fit. The 2RSR version arrives sealed, which suits dusty, wet or lubricant migration conditions, though the seal sets a speed limit that has to be respected. A tapered bore mounts on an adapter sleeve and lets you set residual clearance during installation; a cylindrical bore presses directly onto the shaft, either hot or with the right tooling. Lubrication, support alignment and clean housing conditions drive how long the bearing lasts.
Across manufacturers, a spherical roller bearing is recognized by its numeric designation plus the execution, sealing and cage suffixes. When swapping one brand for another, match bore, outer diameter, width, bore type, internal clearance and sealing arrangement rather than the series number alone. If the codes do not line up exactly, check both data sheets before mounting.
If you have the code engraved on the bearing or the equipment model, send it to MR Industrial Accessories by WhatsApp or email. With the full designation, the brand and the application, the team can confirm the right variant and suggest equivalents.

Frequently asked questions
- FAG 23172-BEA-XL-2RSR-MB1 bearing: what are its dimensions?
- FAG 23172-BEA-XL-2RSR-MB1 measures 360 mm across the bore and 600 mm across the outside diameter; its width is 192 mm (360 x 600 x 192 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23172.
- What does 2RSR indicate on a FAG spherical roller bearing?
- It means the bearing is sealed on both sides. The seals hold lubricant in and keep dust and moisture out, which suits contaminated environments, but they lower the permissible speed compared with an open bearing.
- How do I choose between a tapered and a cylindrical bore?
- The shaft decides it. A tapered bore mounts with an adapter sleeve and allows internal clearance to be adjusted during installation, while a cylindrical bore fits the shaft directly. If the shaft is already machined, the bore type is set.
- Can a bearing from one brand be replaced by another manufacturer's?
- Yes, provided the bore, outer diameter, width, bore type, internal clearance and sealing system match. The numeric designation is a starting point, but suffixes differ between makers. Send the complete code by WhatsApp and it can be verified before quoting.
