SKF QJ MA/C2L bearings are four-point angular contact units built to handle combined radial and axial loads in both directions. Machine tool spindles, gearboxes and transmission equipment are typical homes for this series, where precision and rigidity matter. MR Industrial Accessories LLC supplies the line to customers across the United States and Latin America.
Reading the code helps you order the right piece. QJ marks a four-point angular contact bearing. The digits that follow—QJ 212 MA/C2L or QJ 310 MA/C2L, for example—set the size in the SKF numbering system. MA tells you the cage is machined brass and centered on the outer ring. C2L covers a defined internal clearance together with a particular lubricant; confirm both against your application. Dimensions and operating conditions drive the final part number.
These bearings show up in metalworking, food processing, petrochemical and mining operations. Milling, grinding and boring spindles use them, as do speed reducers, gearboxes and lifting equipment. Because they take axial loads from either direction, they suit assemblies that need stiffness and accuracy. In plants, you will find them in machine tools and positioning systems where repeatability is critical.
Selection starts with load size and direction, running speed and the surrounding environment. Sealing and lubrication deserve attention: the QJ MA/C2L series carries a specific lubricant that must be maintained. When mounting, check shaft-to-housing alignment and set internal clearance to match the C2L suffix. The machined brass cage provides strength and guidance, but handle it carefully to prevent deformation. Review the technical data before installation.
Interchangeability is not automatic. Four-point angular contact bearings appear under similar designations from other makers, yet suffixes and internal clearances can differ. Check critical dimensions and tolerances before swapping one bearing for another brand. Operating conditions determine whether a direct replacement works. MR Industrial Accessories LLC can review the options and compatibilities with you.

Frequently asked questions
- What does the MA suffix mean on a QJ bearing?
- MA indicates a machined brass cage centered on the outer ring. This cage provides strength for high loads and moderate speeds.
- How do I choose the right internal clearance for my application?
- Clearance depends on mounting and operating conditions. The QJ MA/C2L series uses a special C2L clearance. Check the manufacturer's recommendations and factor in temperature and loads.
- Can I replace a QJ bearing with one from another brand?
- Sometimes, but verify dimensions, tolerances and internal clearance first. Designations vary between manufacturers. Send us the original part number so we can assess interchangeability.
