The NU209C3 is a single-row cylindrical roller bearing, engineered to accommodate heavy radial loads and operate at high speeds. With dimensions of 45mm bore, 85mm outer diameter, and 19mm width, this bearing features a C3 clearance, indicating a greater than normal internal clearance, which is suitable for applications involving high temperatures or where shaft expansion is expected. The design allows for axial displacement of the shaft relative to the housing, making it ideal for non-locating bearing positions. It is commonly used in various industrial and agricultural machinery where durability and performance under demanding conditions are critical.
