SKF QJ N2PHAS series bearings are four-point ball bearings built for shafts that see axial load in both directions and have tight radial space. They suit arrangements where a single row of balls must handle combined loads. MR Industrial Accessories LLC supplies these bearings to customers across the United States, Canada, Mexico and South America.

The QJ prefix in the designation indicates a four-point bearing. What follows gives the series and bore: in QJ 214 N2PHAS and QJ 215 N2PHAS, the 2 is the diameter series and 14 or 15 is the bore size. In QJ 304 N2PHAS, QJ 306 N2PHAS, QJ 307 N2PHAS and QJ 309 N2PHAS, the 3 is a different diameter series and the last digit is the bore. The N2PHAS block is read as part of the complete code.

You will find these bearings on shafts that carry axial load in both directions where radial room is limited. Typical equipment includes gearboxes, machine tools, pumps, process fans, conveyors and transmission units. They are common in metallurgical, food, cement and paper plants, as well as in maintenance shops that replace four-point bearings in existing assemblies.

To select the right part number, begin with the bore diameter, outside diameter and the width the housing requires. Then review how the shaft operates: whether axial load acts in both directions, if there is combined radial load, and the speeds involved. During mounting, pay attention to alignment between shaft and housing, support on the shoulders, and lubrication condition, since these determine whether the bearing performs as intended.

If you have a part number from another brand or an unidentified part, we compare the designation and main dimensions to suggest a compatible equivalent from the lines we supply. Interchangeability depends on type, series and mounting dimensions, not only on the number stamped on the part, so it is best to provide the complete part number or the housing dimensions.

For a quote on any bearing in this series, send the QJ part number from the equipment or the shaft and housing dimensions via WhatsApp or email. We quote the exact part number or size you request and respond promptly. Our team can also help you choose and suggest equivalents.
