QJ 248 N2MA

The QJ 248 N2MA four-point contact ball bearing is a versatile single-row bearing designed to efficiently manage substantial axial loads in both directions, along with moderate radial loads. Its distinctive internal design, featuring a 35-degree contact angle, allows for optimal load distribution across four contact points between the balls and raceways, providing high rigidity and stability in operation. The "N2" designation indicates two locating slots in the outer ring, facilitating secure mounting and preventing rotation, while "MA" signifies a machined brass cage, outer ring guided, enhancing its durability and performance under demanding conditions. This bearing is a space-saving alternative to double-row angular contact bearings and finds common application in machine tools, gearboxes, and other precision rotating machinery where bidirectional axial support and reliable performance are critical.
