SKF QJ PHAS bearings are four-point angular contact bearings that handle combined radial and axial loads in both directions. They suit high-precision, high-rigidity arrangements such as machine tool spindles, measuring equipment and positioning mechanisms. MR Industrial Accessories LLC supplies these bearings to customers across the United States, Canada, Mexico and South America.
The QJ PHAS designation follows a simple pattern. The QJ prefix marks the four-point bearing type. The digits after it give the dimension series and the bore code. In QJ 310 PHAS, for instance, 3 is the diameter series and 10 is the bore code. Use the dimension tables to confirm each code before ordering.
These bearings appear in metalworking, automotive, aerospace and machine tool manufacturing. Common installations include milling machine, grinding machine and machining center spindles, high-precision measuring equipment, and antenna or radar slewing mechanisms. Their capacity to take loads in both directions makes them a flexible choice for these duties.
When selecting a QJ PHAS bearing, review the load it will carry, the operating speed and the surrounding conditions. Check alignment during mounting so the bearing is not exposed to extra stress. Correct lubrication and sealing help the bearing reach its expected service life. On a shaft with a fit, follow the manufacturer's recommendations to prevent deformation.
If you compare equivalents from other brands, match the main dimensions and load capacities. Four-point bearings from other makers may carry different designations while keeping similar characteristics. Confirm that the interchange is compatible with your specific application. Our team can help you review the options.
