QJ224-N2-MPA

The QJ224-N2-MPA is a heavy-duty four-point contact ball bearing (120×215×40 mm) engineered to absorb substantial bidirectional axial thrust while occupying minimal envelope space compared to conventional double-row angular contact designs. Featuring a split inner ring configuration, the QJ224-N2-MPA simplifies mounting and dismounting by allowing the outer ring-complete with the ball set-to be installed independently from the inner ring halves. Operational stability is further enhanced through two integral locating slots on the outer ring ("N2" suffix), which prevent anti-rotation slip within the housing under severe duty. Additionally, the robust window-type solid brass cage guided by the outer ring ("MPA" suffix) ensures precise ball tracking, reduced frictional heat, and reliable endurance in high-speed applications such as industrial gearboxes, pumps, and heavy machinery.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
