Precision Brand 42440 Stainless Steel Slotted Shim

Product Description

The PRECISION BRAND 42440 is a slotted stainless steel shim used for precision alignment and leveling of industrial and mechanical equipment. Measuring 4 inches x 4 inches with a thickness of 0.020 inches, this shim installs between mating surfaces to correct misalignment, compensate for wear, or establish precise running clearances. The slotted design allows the shim to slide into position around a shaft or fastener without full disassembly. Maintenance technicians, millwrights, and industrial mechanics reach for stainless steel shims when corrosion resistance and dimensional stability are required in demanding service environments.

This shim is suited for use with motors, pumps, generators, compressors, and other rotating or stationary plant machinery where precise shaft and base alignment is critical. It is appropriate for both initial installation and ongoing preventive maintenance applications in commercial and industrial facilities. The 0.020-inch thickness makes it a commonly specified increment for fine alignment corrections during machinery setup.

Key Features

• Slotted design allows installation and removal without fully unbolting the machine
• Stainless steel construction provides corrosion resistance in wet or harsh environments
• 0.020-inch thickness supports precise, repeatable alignment corrections
• 4 inches x 4 inches footprint fits a wide range of motor and pump base configurations
• Maintains dimensional stability under mechanical load and temperature variation

Compatibility

Designed for use with motors, pumps, generators, and general plant machinery requiring base or flange alignment correction in industrial and commercial maintenance applications.

Installation Notes

Millwrights and industrial mechanics typically install shims during machinery alignment procedures. De-energize and lock out all equipment before performing any shimming or alignment work. Use calibrated alignment tools to verify shaft and base alignment after shim placement. Do not stack excessive numbers of shims in place of a properly sized single shim where structural integrity may be compromised.
