N 222 ECM

Designed to handle intense radial forces, the N 222 ECM stands out as a high-precision solution for rotating equipment requiring seamless axial compensation. Unlike variants with fixed flanges on both rings, this N-series configuration features two integral ribs on the inner ring while maintaining a smooth, flangeless outer ring. This purposeful engineering allows for a "floating" shaft arrangement, effectively absorbing the thermal longitudinal expansion common in high-speed industrial spindles. The core of its durability lies in the ECM designation, which indicates an upgraded internal geometry paired with a machined brass cage (M). This heavy-duty cage is glass-fiber reinforced and roller-centered, significantly reducing friction and heat generation during high-velocity rotations, even under harsh lubrication conditions.

Integrating the N 222 ECM into your machinery-ranging from massive gear reducers to specialized electric motors-offers a distinct advantage in terms of modular installation. Because the components are entirely separable, maintenance teams can mount the inner and outer rings independently, preventing the common risk of scoring during complex assembly processes. With a static load rating of 365 kN and a refined raceway finish, this bearing minimizes vibration and noise levels, directly contributing to a longer Mean Time Between Failures (MTBF). By choosing this SKF Explorer class component, operators ensure their systems can sustain a limiting speed of 4,000 r/min without sacrificing the structural integrity of the bearing arrangement.
