Alignment Shims

An alignment shim in engineering is a thin piece of metal used to fill or pack gaps/spaces beneath the feet of plant machinery, such as pumps, motors & gearboxes.

Alignment Shims are commonly used in conjunction with shaft re-alignment work undertaken on rotating plant machinery, in order to fractionally elevate or lower one machine (most commonly a Motor) so that its rotating shaft is in perfect rotational centreline alignment with shaft of the driven unit (pump, fan, propeller).

Alignment Shims for Industrial Applications

Shims are supplied pre-cut and are available in a range of Metric or Imperial sizes. pre-cut shims are made of high-quality stainless steel to prevent corrosion from acid or alkali exposure.

Pre-cut shims are available in several machine foot sizes, each with different thickness options to give the right alignment correction facility for almost any machine. pre-cut shims are easily and quickly identified by permanent marks indicating thickness.

Pre-cut shims are completely flat, ensuring stability and consistent machine support over the full surface of the shim. Pre-cut shims are burr-free and have specially rounded corners to avoid injury to operatives during alignment and positioning.

Pre-cut shims have an extraction and insertion tab to facilitate positioning and removal, each clearly marked with thickness. Pre-cut shims are available in many pre-packed options to suit your requirements.

Alignment Shim Products

Shims can be supplied in packs of 10-off per size, or in Shim cases containing a variety of thicknesses and profiles as required.Shims can be supplied to fit the following Bolt Sizes: M12, M18, M27, M36, M52.

The use of Laser Shaft Alignment systems for the alignment of rotating plant machinery, such as the Monition laser alignment system, has meant that modern industry can achieve a very high level of precision in the installation and commissioning of plant machinery. Alignment shims are available in thickness starting at 0.025mm, in stainless steel or laminated brass.Monition supply a range of pre-cut stainless steel shims, in both Metric and Imperial sizes, to complement the full range of Monition Laser Shaft Alignment Systems.
