Decoding FAG 23156-BE-XL-K-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-K-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-K-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).

FAG spherical roller bearings are self-aligning, two-row components that handle high radial loads and axial loads in both directions, even when shafts are misaligned. Their design suits applications where shaft deflection or mounting errors are unavoidable. MR Industrial Accessories LLC supplies this line to industrial customers across the United States and Latin America.
The part number carries several suffixes that matter before you request a quote. Take 23140-BE-XL-K-2RSR, 23144-BE-XL-K-2RSR and 23148-BE-XL-K-2RSR: the first digits give the size and dimension series; BE means a brass cage with symmetrical rollers; XL denotes the longer service life design; K is a tapered bore; and 2RSR indicates sealing on both sides. Together, these define a sealed bearing with a taper, built for demanding duty.
These bearings appear in continuous-process industries where reliability is critical: cement plants, steel mills, pulp plants, mining, flour mills and power transmission equipment. They are common in gearboxes, conveyor belts, vibrating screens, ball mills and support rollers. Because they compensate for misalignment, they work well on long shafts or structures that deflect.
Selection depends on load type, rotation speed and environment. The 2RSR seal keeps out dust and moisture, but in highly contaminated areas additional lubrication may be needed. A K tapered bore requires mounting on an adapter sleeve or tapered shaft with the correct internal clearance. Follow the manufacturer's lubrication specification, and keep initial alignment reasonable even though the bearing is self-aligning.
When comparing equivalents from other brands, check the main dimensions, bore type and sealing. Interchangeability is not automatic: the same size may differ in load capacity or internal execution. For a replacement, compare the complete code and the service conditions. MR Industrial Accessories LLC can help with the technical information available.

Frequently asked questions
- FAG 23156-BE-XL-K-2RSR bearing: what are its dimensions?
- FAG 23156-BE-XL-K-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 K suffix mean on these bearings?
- K indicates a tapered bore, generally with 1:12 taper. This allows mounting on a tapered shaft or adapter sleeve, which simplifies internal clearance adjustment and disassembly.
- How do I choose between a sealed and an open bearing?
- The 2RSR seal protects against dust and moisture, making it suitable for contaminated environments. If the bearing runs in an oil lubrication system or needs frequent inspection, an open version may be better. Evaluate your equipment conditions.
- What should I consider when replacing a bearing from another brand?
- Compare the main dimensions, bore type, sealing and load capacity. A matching size number is not enough; verify the complete code and service conditions. If in doubt, consult us with the equipment data.
