Washer for Liebherr CBB 350(200)/18

The washer with part number 940135714 is a mechanical component used to distribute the load of a fastener, such as a bolt or nut, over a larger surface area. This distribution helps prevent damage to the mating material and ensures that the mechanical connection remains secure and stable. In heavy machinery, this component is used to reduce friction during the tightening process and to compensate for surface irregularities between contact points.

This component is compatible with the Liebherr CBB 350(200)/18(31) crane, specifically for units within serial number 162 895. It is integrated into critical structural or system connection points where the stability of bolted joints is required for operational integrity. Proper installation of this washer ensures that fasteners maintain their intended tension, which is necessary for the safe operation of the crane in its intended environment.

In general engineering applications, washers are used to provide a smooth bearing surface for fasteners, preventing the rotational force of a nut or bolt head from damaging the surface of the assembly. They also play a role in maintaining the preload of a bolted joint by providing a consistent surface for the fastener to seat against, which helps prevent loosening caused by dynamic loads or operational vibrations.
