QJ1260-N2-MPA

The QJ1260-N2-MPA four-point contact ball bearing is a specialized single-row angular contact ball bearing, distinguished by its ability to accommodate significant axial loads in both directions, along with a degree of radial load. Featuring a bore diameter of 300mm, an outer diameter of 540mm, and a width of 98mm, this bearing (often from manufacturers like FAG/Schaeffler) includes two retaining grooves (N2) in the outer ring and a robust, outer ring-guided solid brass cage (MPA). Its unique internal geometry, characterized by a 45-degree contact angle, allows for four contact points between the balls and the raceways under purely axial load. This design makes the QJ1260-N2-MPA an excellent choice for applications requiring compact axial space, high stiffness, and efficient handling of alternating axial forces, such as in industrial gearboxes, compressors, pumps, and various types of heavy machinery.
