Shims, also known as spacers or washers, are thin, flat pieces of material used to precisely adjust the space or clearance between two components. They are often used to correct minor variations in dimensions or alignment, ensuring that the components fit together perfectly.
The use of shims is essential because they help minimize wear, improve alignment, and increase the overall efficiency of mechanical systems. They ensure that components work together correctly, which leads to a longer lifespan of machines and equipment.
Thicknesses:
Shims are available in different thicknesses, ranging from 0.005mm to 15mm. These thin shims are ideal for extremely precise adjustments and ensure that even the smallest gap can be filled.
Accuracy:
+/- 15-20µm
The accuracy of the shims depends on material and material thickness
Materials:
The choice of material for shims depends on the specific application and the required properties. Some commonly used options are:
Steel, stainless steel (inox), titanium, aluminum, copper alloys, …
Quality:
High-quality shims have several important properties that distinguish them. They are burrless, meaning they have no sharp edges that could cause damage to other components. They are also corrosion resistant, which is essential for applications in harsh environments.
Extra options:
If desired, the exact thickness of the thickness plate can be applied to the surface using a laser engraving. This engraving is indelible, which ensures reliable identification.
Spacers are used in a wide range of industries. In mechanical engineering they are used for the precise alignment of machine components. In the electronics and semiconductor industries they are essential for positioning delicate parts. They are also used in the medical device industry for the precise assembly of devices.
Each product undergoes strict quality controls to meet the highest standards. Raytech uses a climate-controlled measuring chamber for accurate measurements and a 3D vision measuring machine for detailed measurement reports. This guarantees that each shim meets the customer’s specific requirements.
