NU 2220 ECML

The NU 2220 ECML designation identifies a premier single-row cylindrical roller bearing specifically designed to handle significant radial forces within high-stress environments. Its core geometry features a solid outer ring with two guiding flanges, combined with a plain inner ring devoid of flanges. This design is foundational to its primary function: acting as a non-locating bearing that readily permits the shaft to move axially within the housing, effectively compensating for thermal expansion or minor alignment issues. Enhanced internal architecture, denoted by the EC/E suffix, maximizes dynamic load-carrying capability, while the durable, high-strength machined brass cage (M) ensures precise roller guidance and sustained operation reliability, making it the ideal choice for heavy-duty industrial drives and machinery.

A significant operational benefit of the NU 2220 ECML series is its two-piece, separable construction. This feature allows the inner and outer rings to be mounted independently, drastically simplifying installation procedures and reducing downtime during maintenance or replacement. The bearing conforms to ISO dimensional standards, offering a precise fit with a 100 mm bore, 180 mm outside diameter, and a 46 mm width. Beyond its physical size, the bearing delivers superior operational performance, providing an excellent balance of load rating (e.g., typically exceeding 380 kN dynamic load) and permissible speed. For applications where maximum lifespan and high-efficiency power transmission under continuous, high-load scenarios are critical, the NU 2220 ECML provides a reliable, industry-leading solution.
