SKF 51118 is a single-direction, 90mm inner diameter and 120mm outside diameter thrust ball bearing manufactured by SKF. This bearing is most commonly used for applications requiring heavy axial loads and high speeds, such as axial fans, aerospace and agricultural machinery, lift mechanisms and other industrial equipment applications. It has an open design, making it an ideal choice for applications that are exposed to dirt and moisture. Its carbon steel construction provides excellent rust protection and low maintenance requirements. The bearing runs on a maximum speed of 4,200 RPM and has a dynamic axial load capacity of 39,800 N.
