SKF QJ series bearings are four-point contact ball bearings. They accommodate combined radial and axial loads in either direction, making them a fit for arrangements that call for rigidity and precision. The series includes various cage and internal clearance options.
The part number tells you what you are getting. QJ marks the four-point contact design. The digits after it give the size: in QJ 212 N2MA/C3, the 12 means a 60 mm bore. N2MA is a machined brass cage; C3 is internal radial clearance. In QJ 224 N2MA/C2, C2 is a tighter clearance than standard. Reading these codes correctly lets you order the exact replacement.
These bearings show up in gearboxes, machine tool spindles, centrifugal pumps, industrial fans and transmission equipment where axial loads reverse. They also serve in setups needing high rotational precision and rigidity, such as milling heads or roller shafts. Because they take force in both directions, the support design can be simpler.
When selecting, consider radial and axial load, speed and environment. This series does not come with seals or shields; if contamination is present, look at a sealed bearing instead. Choose C2, C3 or standard clearance based on operating temperature and shaft fit. Lubrication may be grease or oil, and keeping shaft and housing aligned helps avoid parasitic forces.
Other makers offer four-point contact bearings under their own designations. Interchange is not automatic: compare dimensions, load capacity, clearance and cage type. Always verify the complete part number and tolerances before substituting one brand for another. If you send the measurements or the original part number, our team can point you to the right equivalent.

Frequently asked questions
- What does the suffix N2MA mean in a QJ bearing?
- N2MA indicates a machined brass cage, in two pieces, guided by the outer ring. This cage suits high speeds and loads. Keep the suffix when ordering a replacement to maintain the same performance.
- Can I replace a QJ bearing with one from another brand?
- Yes, but check dimensions, load capacity, internal clearance and cage type. Interchangeability is not direct between brands. Send us the original part number and measurements, and we will help you find the right equivalence.
- What lubrication do you recommend for these bearings?
- It depends on speed and temperature. For general use, lithium grease; for high speeds or elevated temperatures, oil. Follow the manufacturer's instructions and maintain proper lubrication to extend service life.
