Scope of product definition
The motor shims given here are adapted by adding or removing sheet layers. There are no adjustable systems which work by means of spindles etc.


Manufacturing method
The manufacturing methods vary considerably according to material and lot size.
Generally speaking, individual stamping tools are used for larger lot sizes. The tool costs are paid off via a very reasonable parts price.Optimised tool combinations are also used for smaller lot sizes; in some cases, these tool combinations are completely unspecific. This means that it is possible to produce individual items, a popular option among customers.


Field of application
Motor shims are mainly used in assembly and in maintenance. Their use can be planned from the start or they can be used afterwards for fine adjustment.


The handling differs according to the type of motor shims. The specific application instructions are to be complied with in this regard; compare also the information under M-Tech®L, M-Tech®P and M-Tech®S.
