SKF angular contact bearings of the QJ MA/C2L series are four-point bearings, designed to support 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. At MR Accesorios Industriales we distribute this line with the backing of more than 80 years in the industrial sector.

The designation of the QJ MA/C2L series is interpreted as follows: the letters QJ identify four-point bearings of the angular contact series. The number that follows, as in QJ 212 MA/C2L or QJ 310 MA/C2L, indicates the bearing size according to the SKF numbering system. The MA suffix indicates that the cage is machined brass, centered on the outer ring. The C2L combination defines a special internal clearance and a particular lubrication, details that should be verified in each application. To select the correct part number, it is essential to know the dimensions and operating conditions.

These bearings are used in Argentine industries such as metalworking, food, petrochemical and mining. They are common in milling machine, grinding machine and boring machine spindles, as well as in speed reducers, gearboxes and lifting equipment. Their ability to support axial loads in both directions makes them suitable for assemblies requiring rigidity and precision. In production plants, they are found in machine tools and positioning systems that demand accuracy.

For a correct selection, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Sealing and lubrication are critical: the QJ MA/C2L series incorporates a specific lubrication that must be respected. During mounting, ensure alignment between shaft and housing, and apply the appropriate internal clearance according to the C2L suffix. The machined brass cage offers strength and guidance, but requires careful handling to avoid deformation. Always consult the technical specifications before installation.

Regarding equivalents and interchangeability, four-point angular contact bearings can be found from other brands under similar designations, although suffixes and internal clearances may vary. It is important to verify the critical dimensions and tolerances before replacing one bearing with another from a different manufacturer. Interchangeability is not always direct and depends on the operating conditions. At MR Accesorios Industriales we can advise you on the available alternatives and compatibilities.
