Description
SKF QJ 207 MA/C2LS1 is a angular contact ball bearing reference, within Bearings. Request a quote for QJ 207 MA/C2LS1 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF QJ MA/C series angular contact bearing is a four-point contact ball bearing designed to support axial loads in both directions and a certain radial load. It is used in applications requiring high rigidity and precision, such as machine tool spindles, gearboxes and power transmission equipment. Its single-row design with a split inner ring allows for simple mounting and precise adjustment of axial clearance.
The QJ MA/C series designation reads as follows: QJ identifies the four-point contact series; MA indicates a machined brass cage, centered on the outer ring; C indicates normal internal axial clearance, and additional suffixes such as LS refer to a special treatment or execution variant. For example, QJ 207 MA/C2LS1 combines size 207 with MA cage, C2 clearance and the LS1 variant. Learn more about this nomenclature at MR Accesorios Industriales.
These bearings are used in main spindles of milling machines, grinding machines and machining centers, where precision and the ability to support combined loads are critical. They are also found in speed reducers, gearboxes, high-pressure pumps and power transmission equipment in the automotive, metallurgical and machine tool industries in Argentina. Their ability to support axial loads in both directions makes them ideal for fixed positions.
To correctly select a QJ MA/C bearing, take into account the axial and radial load it must support, the rotational speed and the lubrication conditions. It is essential to verify the appropriate internal axial clearance for your application; incorrect clearance can cause overheating or noise. Mounting requires precise alignment and, in many cases, adjustment with a lock nut or check nut. Lubrication can be grease or oil, depending on speed and operating temperature.
Regarding equivalents, four-point contact bearings from other brands can be interchanged if the main dimensions, clearance and load capacity match. However, tolerances and cage materials may vary between manufacturers, so it is advisable to verify compatibility. At MR Accesorios Industriales we carry the SKF brand and can advise you on interchangeability with other similar series.

Frequently Asked Questions
- What does the QJ designation mean in an SKF bearing?
- QJ identifies four-point contact ball bearings, which can support axial loads in both directions. The QJ MA/C series includes a machined brass cage and normal axial clearance. It is SKF's own designation for this category of bearings.
- How do I choose the correct axial clearance for my application?
- Axial clearance depends on the load, speed and operating temperature. For high-precision applications, a reduced clearance such as C2 is recommended. Check your equipment conditions and, if in doubt, contact us via WhatsApp for advice.
- Does this bearing come with seals or shields?
- The QJ MA/C designation does not include seals as standard; they are open bearings. For contaminated environments, they can be mounted with additional covers or seals. If you need a sealed variant, ask us about other available options.
