SKF NU 2220 ECP/C3 – 100 mm Cylindrical Roller Bearing

SKF NU 2220 ECP/C3 – 100 mm Cylindrical Roller Bearing

The SKF NU 2220 ECP/C3 is a high-performance, single-row cylindrical roller bearing designed to handle very heavy radial loads. The NU designation indicates a non-locating or “floating” bearing, which allows for axial displacement of the shaft. With an optimized internal design for increased load capacity, a durable polyamide cage, and a larger-than-normal C3 internal clearance, it is a reliable choice for demanding applications with high loads and operating temperatures.

About This Bearing

This product is a single-row cylindrical roller bearing. The NU designation signifies a non-locating design, meaning the inner ring can move axially relative to the outer ring. This feature is crucial in applications where thermal expansion or contraction of the shaft must be accommodated without creating stress on the bearing. The ECP suffix indicates an optimized internal geometry (E) for enhanced load capacity and a polyamide cage (CP), which is lightweight and allows for higher speeds. The C3 clearance is a larger-than-normal internal clearance that prevents the bearing from seizing under high-temperature or interference-fit conditions.
