VEHICLE ALIGNMENT SHIMS

Vehicle alignment shims not only reduce labor costs during installation and repair but also facilitate inventory control and avoid the risk of injury when cutting and inserting sharp-edged shims.  Shim alignment corrects the vertical position of a movable machine so it will be in alignment with the motionless or reference machine.

Sachin shim is a manufacturer, supplier, and exporter of the finest quality coupling shims in Mumbai – India.

After a dial indicator or laser shaft alignment tool is used to measure the misalignment of the two machine’s rotational centrelines, shims are added or removed (as indicated by the alignment tool) from the moveable machine’s feet to correct the vertical angularity and offset.

Shim material can be cut from brass or stainless steel shim stock; however, this process is very labor-intensive and time-consuming. Also, when cutting shims from stock the sharp burrs can be a safety issue as well as creating errors in the “stack up” of the shims.

The best solution is to use Pre-cut Stainless Steel Shims. These shim kits have been in use for decades and are an invaluable tool for the mechanic performing alignments. Plus pre-cut shims have safety tabs to grab when placing under the machine feet as well as having rounded edges without burrs, reducing safety issues associated with shims cut from stock.

Pre-cut Stainless Steel Shim Kits are typically available for machine foot sizes 2″x 2″, 3″x 3″, 4″x 4″, 5″ x 5″ in thickness from .001″ to .005″, .010″, .015″, .020″, .025″, .050″, .075″, .100″, and .125″. Other sizes of thicknesses are available from various manufacturers as are metric shims used in the Wind Turbine industry.

Pre-cut Stainless Steel Shims are a cold-rolled steel product with precise thicknesses, however, shims .050″ and thicker are rolled to a nominal thickness and can vary in thickness by +/- .005″ dependent upon the manufacture. Some manufacturers mark their thicker shims with both the nominal and actual thickness. Thicker shims that are not marked with the real thickness will need to be measured with a micrometer or Vernier caliper during the shaft alignment process.

When using shims during the shaft alignment procedure it’s a good idea to limit the number of shims to 5 or less under the machine feet. Consolidate shims as much as possible as a large stack of thin shims can induce a soft foot.
