View model pageGeneral guidance
In general, a washer is a flat, thin ring placed under a fastener or between parts to spread load, maintain spacing, or help control fit and movement at a joint. Catalog descriptions of washers typically give dimensions to identify the piece, and the exact role of any specific washer depends on its location in the assembly.
Use part number 0302179 as the reference for this washer. Before ordering, compare the listed dimensions and the catalog occurrences with the machine and assembly you are working on, since a catalog association does not by itself confirm compatibility for every configuration.
