The FAG four-point bearing of the QJ-XL-N-TVP series is an angular contact ball bearing with a particular feature: a single row of balls that, thanks to the geometry of its raceways, can support axial loads in both directions as well as radial loads. It is used in applications where axial space is limited and rigidity and combined load capacity are required, such as gearboxes, machine tools or transmission equipment.

The designation of this series is read in blocks. The letters QJ identify the four-point design. The number that follows —as in the example QJ218-XL-N2-TVP— indicates the size and dimensional series. The suffix XL corresponds to the current generation of the product, with internal improvements over previous versions. The N followed by a digit refers to variants in the number of balls or in the ring design. The suffix TVP indicates the cage type: polyamide window, ball-guided. Recognizing each block allows you to compare with other nomenclatures and request the exact part number.

In Argentine industry, this type of bearing appears in gearboxes and gear cases, machine tool spindles, process pumps, industrial fans and power transmission equipment. It is also found in applications where the bearing is required to support axial load in both directions with a single support, which simplifies the assembly design and reduces the space occupied. It is common in metallurgical, food, cement plants and in the oil & gas sector.

To select the correct bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Sealing or external protections are key if there is dust, moisture or particles. Lubrication must be suitable for the temperature and speed: grease or oil as appropriate. Mounting requires precise alignment between the supports and correct fit on the shaft and in the housing, since this type of bearing is sensitive to misalignment. Follow the manufacturer's recommendations for internal clearance and tightening torque.

When looking for equivalents, keep in mind that each manufacturer uses its own nomenclature for four-point bearings. The same size may appear with different part numbers depending on the brand. Therefore, the safest approach is to compare the main dimensions —bore, outer diameter and width— and the load capacities, rather than relying only on the part number. At MR Accesorios Industriales we sell FAG as an official brand and we can guide you to find the equivalent reference if you send us the data for your application.
