SKF QJ series bearings are four-point angular contact ball bearings. They handle radial and axial loads in both directions and suit setups that call for precision and rigidity, including machine tool spindles, gearboxes and transmission equipment. MR Industrial Accessories LLC supplies this line to customers in the United States and several Latin American countries.
Reading the code: QJ marks a four-point angular contact ball bearing. The digits that follow give the bore diameter through a dimensional code. Suffixes describe internal design and cage. N2 means a groove in the outer ring for retention; MA means a machined brass cage centered on the outer ring. QJ 212 N2MA, QJ 214 N2MA and QJ 217 N2MA follow that same structure, differing only in bore size.
These bearings appear in metalworking, food, chemical and steel operations. Typical positions include milling and grinding spindles, rotary tables, speed reducers and pumping equipment. Because they take axial load in both directions, they fit applications that need accurate positioning and high axial rigidity, such as machine tools and measuring equipment.
When selecting a QJ bearing, review the axial and radial loads, the operating speed and the surrounding conditions. Check internal clearance and lubrication: grease or oil can be used, and oil is recommended for high-speed work. Mounting calls for careful alignment and, in many cases, an interference fit on the inner ring to hold precision. Sealing depends on how contaminated the environment is; variants with protective plates exist.
On interchangeability, SKF QJ series bearings can be replaced by products from other brands that use the same international designation. Tolerances and internal clearance may differ between manufacturers, so confirm them before substituting. Consulting a specialist helps ensure dimensional and functional compatibility. MR Industrial Accessories LLC can advise you using the exact code.

Frequently asked questions
- What does the QJ designation mean in a bearing?
- QJ identifies four-point ball bearings with angular contact. The following number indicates the bore diameter, and suffixes such as N2 and MA describe design features, such as the retention groove and the cage type.
- How do I choose the right QJ bearing for my application?
- Consider the radial and axial loads, speed, lubrication and environment. Verify the internal clearance and mounting. For a precise selection, send the code and the working conditions to our technical team.
- Are SKF QJ bearings interchangeable with other brands?
- In general, they can be replaced by bearings from other brands that share the same designation and dimensions. Tolerances and internal clearance may vary, so check them before replacing. We can help confirm compatibility.
