A square shim plate is a type of shim plate with a rectangular (square) outside shape.
A shim plate is a component that is inserted between components or between components and equipment or locations to adjust the position, level, and spacing between them. Square shims are mainly classified as base shims and are used to correct and adjust the level and gap misalignment between parts during the assembly of machine components.
This adjustment reduces machine vibration and noise, prevents machine damage, and ensures stable operation.
In addition to square shims, shim plates include shim rings used for bearings and flanges, and shim tapes that can be cut to any length.
Figure 1. Example of square shim use
Square shims are often used as base shims for fine adjustment of levels between parts. Square shims are available in various thicknesses, for example, t0.05 to t1.0 mm for the same shape, and are adjusted to meet the required accuracy by combining one or more shims.
Square shims, in particular, are prepared in standardized dimensions in terms of size, thickness, and with or without drilling, making it easy to select the dimensions that fit. Therefore, they are used to adjust the level of general-purpose pump motors, pillow blocks, etc., and to adjust the inclination of equipment and facilities that require accurate leveling.
In the above example, a motor is used as a drive for a centrifugal fan. Angular shims (shims for the base) are inserted between the base on which the motor is installed and the motor mounting legs to adjust the tilt and level of the motor. As a result, the center of the motor output shaft - coupling - fan shaft is straight and accurate rotation is possible without vibration.
Spacers are also used to adjust gaps and spacing, but they are primarily used for adjusting the position of parts, not for adjusting the tilt and level. Liners are also used for the same purpose as shims, but with a thickness of t1.0 mm or more.
When high precision is required, simple installation of parts may not be enough to achieve the required accuracy. However, when the number of parts is large, it is not uncommon for the tolerance to accumulate and not be within the required accuracy after the entire assembly is completed.
Therefore, shim plates such as square shims are used for fine adjustment to ensure the required accuracy. The accuracy of the overall assembly is adjusted by inserting square shims between parts to change the tilt of the parts and the level of the parts.
The thickness of the square shim itself also requires accuracy and has a tolerance. It is important to check the thickness accuracy of the square shim to ensure that it meets the required accuracy. For the thickness accuracy, please refer to the dimensional table of each manufacturer.

The main types of corner shim shapes are as follows:
Mounting holes and slots are mainly used for machines and equipment that are mounted and assembled with bolts. Slotted mounting holes allow insertion of bolts without completely removing them.
Alignment shims also have a portion to hook a tool or other object to facilitate insertion and withdrawal operations.

The following are the main types of materials used for square shims. For the selection of materials for square shims, stainless steel or aluminum is used if the environment in which they will be used, such as corrosion resistance.
