QJ 224 N2MA

The QJ 224 N2MA is a specialized four-point contact ball bearing designed to handle complex load conditions within a compact footprint. Its defining feature is the unique raceway geometry, where the arcs are designed to create four distinct contact points between the single row of balls and the rings. This model includes a two-piece inner ring and a solid brass cage (N2MA) centered on the outer ring, which provides exceptional strength and stability, even at high speeds. This robust construction is engineered for reliability in demanding operational environments where both precision and durability are required.

The principal advantage of the QJ 224 N2MA bearing is its remarkable load-handling versatility. It is engineered to support significant axial loads in both directions, as well as a degree of radial load, all from a single bearing position. This capability allows it to replace a pair of angular contact bearings in many applications, leading to considerable space savings and a simplified, more compact machine design. The result is a more efficient and cost-effective assembly, reducing both the component count and mounting complexity while delivering the high performance necessary for gearboxes, pumps, and other industrial machinery.
