Spherical washer for Demag AC80-1

The spherical washer 508 152 98 serves as a precision component within the Demag AC80-1 crane. This assembly consists of two interlocking pieces, a concave and a convex part, which allow for a degree of pivoting. Its primary function is to compensate for angular misalignments between joined components, which helps to ensure a more uniform distribution of load across the connection point and prevents the concentration of stresses in specific areas.

This component is utilized in the Demag AC80-1, specifically in bolted joints that are subject to dynamic loads, vibrations, or structural movements, such as those found in slewing systems, chassis supports, or various structural articulations. By allowing for slight adjustments, the washer helps maintain the integrity of the connection even when bolts or shafts are not perfectly aligned or when structural flex occurs during machine operation.

Spherical washers of this type are used in heavy machinery to facilitate proper seating of fasteners in non-parallel surfaces. They function by providing a self-aligning interface that prevents bending stresses from being transferred to the bolt or stud, thereby reducing the risk of fastener fatigue and loosening in critical structural assemblies.
