What is laminated shim stock?
Laminated Shims have peelable layers of metal which are removed until the Shim has the proper thickness. They are built up from layers of precision gauge metal foil. The peelable Shim layers are bonded into a rigid structure that appear and function as a solid sheet or plate.
How do you peel laminated shim stock?
It consists of multiple layers of thin metal foil that are laid over each other like lamellae and bonded across the entire surface of each (laminated). The individual layers can be peeled of with a knife until the thickness necessary for distance adjustment has been reached.
What are shim washers?
Shim washers, often referred to as shims, are thin washers designed to stack under the head of a screw to create highly precise spacers in a number of applications. They are commonly used to ensure that a surface is level or to remove excess space to play within a mechanism.
What is the difference between a shim and a washer?
For example, shims level a space for working, fill gaps or excess space, and provide increased support, while washers are used to maintain consistent temperatures and change drag precision with pressure. Typically, a shim is fabricated in the shape of a wedge, and tapered to fill spaces or gaps between two surfaces.
Can you use washers as shims?
Some machines may call for a washer to be used as the spacer. If you do this, be sure to use the right type of washer and make sure that you know it will work. In most cases, it is more appropriate to use a shim as a spacer, because that is the primary responsibility of a shim.
What adhesive do you use for brass shim stock?
Cyanoacrylate adhesives or instant adhesives are ideal for bonding brass.
What is shim stock used for?
Shim stock is typically used for support, leveling, and fit adjustment. Some common applications include electrical insulation, seal joints, and adjusting valve spring pressure.
How thick should a shim be?
Thinner shims, usually 0.020″ and thinner, are made from ground stock. Most of these shims are accurate to +/-. 0005″. Thicker shims, usually those 0.025″ and thicker, are made from rolled stock.
Can I use a spacer instead of a washer?
Most people only use washers as a temporary spacer until they can replace it with a more permanent, appropriate part. If you need a spacer right away, you can use the washer and then get a different spacer to replace it.
What is the difference between a spacer and a washer?
Washers and spacers are generally the same thing. Only difference is that spacers have a certain thickness so that they can be used to space something a certain amount. They are consistent in that thickness where washers aren`t. For adapter bolts, they are likely just washers.
What kind of material is a Laminated shim?
Following description of the laminated shim material is based on AMS-DTL-22499 (formerly MIL-S-22499). Other specifications include BOEING BACS40- series, BELL 120- series, LOCKHEED/BOEING 5PTC series, VOUGHT NORTHROP GRUMMAN GS and CVC series.
Is the accupeel Laminated shim material peelable?
AccuPeel® Laminated Shim Stock is manufactured to be a precise, easily peelable shim material per the latest revisions of AMS-DTL-22499 (formerly MIL-S-22499), AMS 4013, AMS 5500 and AMS 4508. Utilizing the latest technology, AccuPeel® Laminated Shim Stock materials provide a uniform, even peel throughout the sheet.
How is the thickness of a shim adjusted?
Thickness of shims made from laminated shim stock can be adjusted in the field by peeling off one layer of lamination a time. Following description of the laminated shim material is based on AMS-DTL-22499 (formerly MIL-S-22499).
What kind of shim stock is corrosion resistant?
Aluminum shim stock is lightweight and nonmagnetic. It has good corrosion resistance. Brass shim stock is corrosion resistant and nonmagnetic. Polyimide plastic shim stock is corrosion resistant, electrically insulating, and holds its shape at extreme temperatures.
