Alignment Shims

Aashish Metals is an alignment shims manufacturer and supplier, cutting precision shims to size for aligning, leveling and spacing machinery. Alignment shims are the thin, accurately made spacers that sit under a motor foot, a pump, a coupling or a bearing housing to bring it into true, and getting them in the exact thickness and shape you need is the whole job. We make them solid, slotted and laminated, in stainless steel, brass, copper and more, as part of our full shims range. Tell us the size, thickness and material and we cut to your drawing.

Because we cut in-house rather than resell catalogue parts, the thickness, footprint and slot are made to your requirement, from a few thousandths of an inch upward, in small or large quantities. If you lead with the metal, go straight to our stainless steel shims or brass shims pages; if you lead with the job, stay here and the material choice is covered below. Either way it is one supplier, cut to size, with fast turnaround.

Types of Alignment Shims

Alignment shims come in three main constructions, chosen by how you need to adjust the gap.
Type What it is Best for
Solid shims A single sheet cut to a fixed thickness Known, fixed adjustment where the gap is measured in advance
Slotted shims Shims with an open slot or U-cut so they slide in around a bolt Machine feet and couplings, fitted without fully removing the bolt
Laminated / peelable shims Bonded layers that peel away one at a time to reduce thickness Fine on-site adjustment where the exact gap is found by trial

Materials We Cut Alignment Shims In

The material is chosen for the environment and the load. Each links to its own page for grade detail and sizes.
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
For stainless specifically, the two most-asked grades are 304/304L shims for general alignment and 316/316L shims where the shim sits in a wet or coastal environment.

Cut to Size: Thickness, Shape & Tolerance

The value of a shims manufacturer is in the cutting, and this is what we hold to:

  • Thickness: from a few thousandths of an inch up to plate thickness, in the increments your alignment needs, including laminated stacks that peel to a target.
  • Shape: solid rectangles, round shims, slotted and U-cut shims, and custom footprints cut to your drawing or sample.
  • Quantity: single prototype shims through to production runs, with common sizes held in stock for fast dispatch.
  • Marking: thickness marking on request so the right shim is picked on the shop floor.

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.
