Stephens Gaskets offers you the best in laminated shims and foil, but why choose these particular shims over others? What are laminated shims and which applications can they be used in?
A shim is basically a thin piece of metal which is used to adjust the fit or alignment of a piece of machinery. Looking at it more in-depth, there are three main uses of shims in a mechanical assembly: tolerance compensation, precision alignment, and wear compensation. In tolerance compensation, the shim is used during the design stage to compensate for precision tolerances during its assembly. Precision alignment refers to elements that need to be coupled, where shims are used to keep the parts in their correct alignment. On the other hand, wear compensation refers to the function of shims to compensate for wear, helping the machinery to keep its desired accuracy and reducing the need to replace parts that have suffered from wear.
When it comes to laminated shims, they have several important features that make them perfect for certain applications. For example, they have many layers that can be peeled back to create the desired thickness. These layers are achieved by using either metal foil or a composite that is bonded – using pressure – to create a rigid structure. These bonded layers mean the shims respond well in a machine environment, and they can be easily adjusted by taking off another layer.
Other advantages of using a laminated shim and foil include a reduction of assembly time, a lower cost, increased precision, dimensional accuracy, and quick production line repairs and adjustments. While the type of applications that can benefit from laminated shims are wide ranging, the main applications include pumps, motors, gas turbines, hydraulic controls, refrigeration, machine tools, agriculture equipment, extrusion, and more. Laminated shims are often put to use in the automotive and aerospace industries, or any application where rotating shafts and sliding surfaces need to remain parallel, where accumulated tolerances need to be controlled, or where the dimensions of a machinery part can be changed by crushed forces or sliding wear.
