The SKF QJ MA/C series is a single-row four-point contact ball bearing. Its split inner ring allows straightforward mounting and fine adjustment of axial clearance. It handles axial forces in either direction plus some radial load, which suits arrangements that need high rigidity and precision.
Reading the code: QJ denotes the four-point contact design. MA means a machined brass cage guided on the outer ring. C stands for normal internal axial clearance. Extra suffixes, for instance LS, mark a special treatment or execution. So QJ 207 MA/C2LS1 pairs size 207 with an MA cage, C2 clearance and the LS1 variant.
Typical positions include milling, grinding and machining center spindles, where accuracy and combined load support matter. You will also find these bearings in speed reducers, gearboxes, high-pressure pumps and power transmission equipment across the automotive, metallurgical and machine tool sectors.
When selecting, review the axial and radial loads, the running speed and the lubrication regime. Confirm the internal axial clearance suits the application; the wrong clearance can lead to overheating or noise. Mounting calls for precise alignment and, often, adjustment with a lock nut or check nut. Grease or oil lubrication works, depending on speed and operating temperature.
For equivalents, four-point contact bearings from other makers may interchange when the main dimensions, clearance and load capacity align. Tolerances and cage materials can differ, so verify compatibility. We supply the SKF brand and can advise on interchangeability with similar series.

Frequently asked questions
- What does QJ indicate in an SKF bearing?
- QJ is SKF's designation for four-point contact ball bearings, which accept axial loads in both directions. The QJ MA/C series adds a machined brass cage and normal axial clearance.
- How do I determine the right axial clearance?
- Clearance depends on load, speed and operating temperature. High-precision setups often use reduced clearance such as C2. Check your equipment conditions and contact us via WhatsApp if you need guidance.
- Are seals or shields included?
- The QJ MA/C designation covers open bearings without seals. In contaminated environments, add external covers or seals. Ask about other variants if you need a sealed version.
