Alignment shims are thin metal spacers with a high degree of accuracy that are placed between the parts of the structure of an industrial machine to fill the gaps, correct misalignment, or allow proper positioning of the parts. The accuracy alignment shims are used to ensure that there is the right spacing of equipment parts, minimise vibration, eliminate premature wear and enhance the overall performance of machines involved in pumps, motors, turbines and heavy equipment machinery. Good machine alignment shims make sure that the rotating parts are run in a worthy and secure manner.
Aashish Metal and Alloys manufactures motor alignment shims, automotive alignment shims, and industrial precision shims to tolerances of ±0.005mm. Our shims are supplied in SS 304, SS 316, brass, copper, and specialist alloys, in stock thicknesses from 0.02mm to 5.0mm, ready for immediate dispatch or custom cut to drawing.
What Are Alignment Shims?
Alignment shims are precision components used to adjust equipment positioning, maintain proper spacing, and achieve accurate alignment between machine components. They are commonly installed beneath motor bases, machinery, bearings, and other equipment where small adjustments are required for correct positioning and operation.
Available in different thicknesses, widths, and lengths, alignment shims allow engineers and maintenance teams to compensate for gaps, level equipment, and make precise alignment corrections. Their size and thickness can be selected according to the equipment requirements and installation conditions.
Alignment shims are widely used in motor alignment, bearing adjustment, machinery leveling, and equipment installation where accurate positioning is important for reliable performance.
Alignment Shim Sizes
Alignment shims are available in a range of thicknesses, widths, and lengths to suit different machinery alignment and leveling requirements. Common shim thicknesses can range from thin precision shims to thicker pieces used for larger alignment adjustments.
The required alignment shim size depends on factors such as the equipment type, gap being corrected, load, mounting surface, and required alignment accuracy. Shims can be supplied in different dimensions and configurations to fit motor bases, bearings, pumps, gearboxes, and other industrial equipment.
For accurate selection, specify the required shim thickness, width, length, material, and quantity according to the equipment and application requirements.
Materials We Cut Alignment Shims In
| Material | Why choose it | Go to |
|---|---|---|
| Stainless steel | The default: corrosion resistance and strength for most machinery alignment | Stainless shims (304, 316) |
| Brass | Non-sparking and corrosion resistant, easy to cut, good for electrical and general use | Brass shims |
| Copper | High conductivity and softness for electrical and precision shimming | Copper shims |
| Aluminium & others | Light weight or special requirements, cut to order | On enquiry |

Where Alignment Shims Are Used
Alignment shims do the same job across many industries: closing the small gap that brings a machine into true. Common uses include motor and pump alignment, where shims under the feet correct soft foot and vertical offset; coupling and shaft alignment, where slotted shims fit around the bolts; bearing and housing spacing; base-plate and skid leveling during installation; and general machine setup where a precise, stable gap must be held. In every case the shim has to be the exact thickness, flat, and stable under load, which is why cut-to-size accuracy matters more than it looks.
Alignment or Precut Shims?
If you need a specific custom size for an alignment job, this page is the right place and we cut to your requirement. If instead you want ready-made shims in standard sizes to keep on hand, our precut shims page covers standard slotted and solid shims in kits and common dimensions. Many workshops use both: precut kits for routine work and custom alignment shims for the odd sizes. Tell us which you need, or both, and we will quote accordingly.
Why Aashish for Shims
As a shims manufacturer and supplier we cut in-house, which is why the thickness, shape and material are made to your requirement rather than picked from a limited catalogue. Common sizes and materials ship quickly from stock, custom and laminated shims are made to order, and everything is cut flat and to tolerance so it seats properly under load. Material certificates are provided where the shim grade matters, for example stainless in a corrosive area. From a single alignment shim to a production run across stainless, brass and copper, it is one supplier and one point of contact. Our full shims range covers every material and type in one place. Send the size, thickness, material and quantity and the quote comes straight back.
Frequently Asked Questions About Alignment Shims
Alignment shims are small, low-density spacers cut to precise dimensions to make parts fit together. They correct misalignments, fill gaps, and support machinery in achieving optimal performance by reducing vibration and wear.
Alignment shims play a crucial role in machinery and vehicle setups. They eliminate unwanted friction and vibration between components, extend equipment lifespan, and minimize maintenance needs by maintaining proper part positioning.
First, measure the body width and rotor bore depth. Subtract rotor bore depth from body width, then add the distance from gearbox face to bearing pocket. Subtract the rotor-to-bearing measurement and add the backface clearance specified in the service manual.
