SKF angular contact bearings of the QJ series are four-point ball bearings, designed to withstand combined radial and axial loads in both directions. They are used in applications requiring high precision and rigidity, such as machine tool spindles, gearboxes and transmission equipment. MR Accesorios Industriales sells this line.

The QJ series designation is interpreted as follows: the letters QJ identify four-point ball bearings with angular contact. The number that follows indicates the bore diameter according to a dimensional code. The N2 and MA suffixes provide information about the internal design and the cage: N2 indicates a groove in the outer ring for retention, and MA indicates a machined brass cage, centered on the outer ring. For example, QJ 212 N2MA, QJ 214 N2MA and QJ 217 N2MA share the same designation structure, varying in size according to bore diameter.

These bearings are used in industries such as metalworking, food, chemical and steel. In Argentina, they are common in milling machine and grinding machine spindles, in rotary tables, in speed reducers and in pumping equipment. Their ability to withstand axial loads in both directions makes them suitable for applications requiring precise positioning and high axial rigidity, such as machine tools and measuring equipment.

To select a QJ bearing, take into account the axial and radial load it must withstand, the operating speed and the environmental conditions. It is essential to verify the internal clearance and the type of lubrication: these bearings can be lubricated with grease or oil, and in high-speed applications oil lubrication is recommended. Mounting must be done with careful alignment and, in many cases, with an interference fit on the inner ring to ensure precision. Sealing will depend on the contamination of the environment; there are variants with protective plates.

Regarding equivalents and interchangeability, SKF QJ series bearings can be replaced by products from other brands that follow the same international designation. However, it is important to verify tolerances and internal clearance, as they may vary between manufacturers. Always consult a specialist before replacing a bearing, to ensure dimensional and functional compatibility. MR Accesorios Industriales can advise you with the exact code.
