In precision engineering and industrial assembly, even the smallest gap or misalignment can affect performance, efficiency, and safety. This is where shim plates come into play. These thin, flat metal components may seem minor, but they are essential in achieving exact alignment and tolerance in machinery, structures, and components.
At AB Steel, we manufacture and supply a wide range of high-quality shim plates to meet the demands of various industries, including automotive, aerospace, construction, oil & gas, and marine sectors.
What Is a Shim Plate?
A shim plate is a thin, flat piece of metal used to adjust the spacing between two surfaces or components. It is typically inserted between parts to align them properly, compensate for wear, absorb vibration, or distribute load evenly.
Shim plates are also known as shim sheets, and they are vital in applications where tight tolerances and precise leveling are required.
Why Shim Plates Are Used
Shim plates serve several essential functions in industrial settings:
- Alignment Correction – Helps in aligning machinery parts and correcting angular misalignment
- Spacing Adjustment – Used to fine-tune the distance between components
- Vibration Reduction – Acts as a buffer to reduce shock or vibration in rotating equipment
- Wear Compensation – Can be added to worn-down surfaces to restore original positioning
- Load Distribution – Assists in evenly distributing weight across structural connections
