UniCarriers Shim 0.5 mm – NI59118-20H01

Measuring 0.5 mm thick, this UniCarriers shim sets clearance and alignment in an assembly by taking up the small gap between two mated parts. A shim of this precise thickness is what brings a bearing preload, a gear mesh, or a mounting face into its specified tolerance, and stacking or swapping shims is the standard way that clearance is dialed in.

Because the thickness is the whole function, the 0.5 mm dimension is the spec that matters; a shim of the wrong thickness leaves the joint either too tight or too loose. This is a UniCarriers part for the assembly position it was cataloged to serve. Confirm the thickness and the fit against the shim being replaced, since a shim stack is built to a target dimension.
