The NSK QJ series covers four-point angular contact ball bearings. A single bearing of this design handles combined radial and axial loads in one direction, so it can take the place of a bearing combination and free up space in the assembly. Typical uses are machine tool spindles, gearboxes and transmission equipment, where precision and rigidity matter.

Reading the designation is straightforward. The letters QJ indicate a four-point angular contact ball bearing, and the number that follows sets the size and relates to the bore. QJ 206, QJ 207 and QJ 208 are three sizes in the same series. Suffixes, when present, can point to differences in cage design, internal clearance or sealing, but for this series the available information does not list them. Confirm the full part number when you send your inquiry.

These bearings appear in metalworking, food, chemical and mining operations, on pumps, compressors, fans, conveyor belts and machine tools. They suit arrangements where axial loads in both directions have to be carried by one bearing, and they run at moderate and high speeds, which fits belt and gear drives.

Selection starts with the axial load, the rotation speed and the operating environment. Shaft-to-housing alignment has to be precise, because the bearings do not tolerate misalignment well. Grease or oil lubrication, applied correctly, supports service life. In dusty or damp conditions, consider extra sealing. Use the right tools during assembly to keep the raceways free of damage.

NSK QJ series bearings can be interchanged with products from other makers that use the same international nomenclature, such as SKF, FAG or NTN, as long as dimensions and load capacities match. Tolerances and internal clearance can differ from one manufacturer to another, so check them. Send us the original part number if you are unsure, and we will point you to the compatible alternative.
