FAG spherical roller bearings are self-aligning two-row components, designed to withstand high radial loads and axial loads in both directions, even with misaligned shafts. Their self-aligning design makes them suitable for applications where shaft deflection or mounting errors are unavoidable. MR Accesorios Industriales supplies this line for industrial equipment in Buenos Aires, Argentina.
The designation of this series combines several suffixes that should be interpreted before requesting a quote. In the examples 23140-BE-XL-K-2RSR, 23144-BE-XL-K-2RSR and 23148-BE-XL-K-2RSR, the initial number indicates the size and the dimension series. The letters BE correspond to an execution with brass cage and symmetrical rollers; XL identifies the longer service life design; K indicates a tapered bore; and 2RSR indicates sealing on both sides. This combination defines a sealed bearing, with taper and suitable for high demands.
These bearings are used in continuous process industries where reliability is critical: cement plants, steel mills, pulp plants, mining, flour mills and power transmission equipment. In Argentina, they are commonly found in gearboxes, conveyor belts, vibrating screens, ball mills and support rollers. Their ability to compensate for misalignment makes them ideal for mounting on long shafts or structures subject to deflection.
To select correctly, take into account the type of load, the rotation speed and the environmental conditions. The 2RSR sealing protects against dust and moisture, but if the environment is highly contaminated it may require additional lubrication. The K tapered bore requires mounting on an adapter sleeve or tapered shaft, with the appropriate internal clearance. Lubrication must be as specified by the manufacturer and the initial alignment, even though the bearing is self-aligning, must not be excessive.
When looking for equivalents with other brands, always verify the main dimensions, the bore type and the sealing. Interchangeability between manufacturers is not automatic: the same size may differ in load capacity or internal execution. If you need to replace an existing bearing, the safest approach is to compare the complete code and the service conditions. MR Accesorios Industriales can advise you with the available technical information.
To proceed with the quote, send via WhatsApp the complete code of the bearing you need, for example 23140-BE-XL-K-2RSR or 23156-BE-XL-K-2RSR. If you do not have it at hand, provide the main dimensions and working conditions. At MR Accesorios Industriales we will reply shortly with the right alternative for your equipment.

Frequently Asked Questions
- What are the dimensions of the FAG 23144-BE-XL-K-2RSR bearing?
- The FAG 23144-BE-XL-K-2RSR bearing has a 220 mm bore, a 370 mm outside diameter and a 120 mm width (220 x 370 x 120 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23144.
- What does the K suffix mean on these bearings?
- The letter K indicates that the bearing has a tapered bore, generally with 1:12 taper. This allows it to be mounted on a tapered shaft or on an adapter sleeve, which facilitates adjustment of the internal clearance and disassembly.
- How do I choose between a sealed and an open bearing?
- The 2RSR sealing protects against dust and moisture, ideal for contaminated environments. If the bearing operates in an oil lubrication system or requires frequent inspection, an open execution may be preferable. Evaluate the conditions of your equipment.
- What should I consider when replacing a bearing from another brand?
- Compare the main dimensions, the bore type, the sealing and the load capacity. It is not enough for the size number to match; verify the complete code and the service conditions. If you have doubts, consult us with the equipment data.
