Arbor Shims

Arbor Shims

Arbor shims, also known as slitter shims, are thin, washer-like discs designed to prevent axial movement in assembled components. Unlike washers, arbor shims are manufactured from precise materials to specific tolerances for an exact fit. They are used for spacing and alignment in machinery applications on milling cutters, saws, and grinding tools. They can also be found in automotive applications such as air locking differentials.
