The FAG QJ-XL-N-TVP is a single-row angular contact ball bearing of the four-point type. Its raceway geometry lets it carry radial loads together with axial loads in either direction. This makes it a practical choice where axial space is tight and the assembly needs stiffness and combined load capacity, as in gearboxes, machine tools and transmission equipment.

The part number is built from distinct blocks. QJ denotes the four-point design. The following number, as in QJ218-XL-N2-TVP, gives the size and dimensional series. XL marks the current product generation with internal improvements over earlier versions. N plus a digit covers variants in ball count or ring design. TVP identifies the cage: a ball-guided polyamide window cage. Reading each block helps you cross-reference other nomenclatures and order the exact part number.

In industrial plants, this bearing type shows up in gearboxes and gear cases, machine tool spindles, process pumps, industrial fans and power transmission equipment. It also suits arrangements where one support must take axial load in both directions, which simplifies the assembly design and saves space. It is common in metallurgical, food, cement and oil & gas facilities.

Selection depends on the magnitude and direction of the loads, the rotation speed and the environment. If dust, moisture or particles are present, sealing or external protection is important. Lubrication must match the temperature and speed, using grease or oil as appropriate. Mounting calls for precise alignment between supports and correct fits on the shaft and in the housing, since this bearing type is sensitive to misalignment. Follow the manufacturer's recommendations for internal clearance and tightening torque.

When searching for equivalents, remember that each manufacturer uses its own nomenclature for four-point bearings. The same size may carry different part numbers from different brands. The safest method is to compare the main dimensions —bore, outer diameter and width— and the load capacities, rather than relying only on the part number. MR supplies FAG and can help you find the equivalent reference if you send the application data.
