shims

Slotted shims come in six sizes from Daemar.

Among the aligning components that Daemar Inc. supplies is a line of slotted shims, used for shaft alignment of rotating equipment. Without proper alignment of power-source shafts with mating-equipment shafts, damaging vibration or excessive shaft and bearing wear may lead to mechanical breakdowns. The convenient slot in each shim allows users to insert, remove, or adjust it without taking machinery apart, while the tabs enable easy insertion and removal.

The tightest on the market

Daemar’s slotted-shim inventory boasts the tightest tolerances on the market, as well as the flattest designs. Businesses use these units for alignment in a wide range of applications and sectors, like fans, pumps, blowers, turbines, die stampers, compressors, punch presses, gearboxes, journal boxes in steel mills, and machinery in chemical plants, paper mills, power plants, refineries, and HVAC facilities.

Slotted shims come in six sizes from Daemar. Customers should first consider the bolt diameter when selecting a size: the shim must fit around the bolt with sufficient clearance to keep threads from biting into the shim, but the gap should not be larger than the washer on the foot bolt. It is also important to measure shim stacks with a micrometre or calliper, preferably in the inside radius of the shim.

The Daemar team recommends using fewer, thicker shims instead of many thin ones – preferably no more than three or four under each foot. For machines that require a lot of shim, it is best to use one thick steel block, which should be ground flat, and few shims. When shims are placed under machine feet, slimmer ones should be sandwiched between thicker ones when possible. Shims must be clean and flat, and they must be placed under the motor feet until they contact the bolt and then pulled back a little.

Slotted-shim kits make the process of shaft alignment easier, and they are available in the six standard sizes. Each kit contains 20 slotted shims in various thicknesses. Every carrying case is made of steel and features a shim lock to stop the shims from moving around when transported.
