Bearing Shims: Your Essential Guide to Precision Alignment and Reduced Wear

Why Bearing Shims Matter

Bearing shims play a crucial role in ensuring proper shaft alignment in rotating equipment. Precision alignment reduces vibration, noise, and wear, extending the life of bearings and other components by up to 30%, according to the American Petroleum Institute (API).

Benefit	How To
Maintain optimal bearing clearance	Use shims of various thicknesses to adjust the spacing between the bearing housing and the shaft
Compensate for manufacturing tolerances	Select shims to accommodate slight variations in component dimensions
Prevent premature bearing failure	Eliminate misalignment by using shims to align shafts within specified tolerances

Advanced Features of Bearing Shims

Bearing shims are typically made from high-strength materials such as stainless steel or composite materials, ensuring durability and precision. They are available in a wide range of sizes and thicknesses to meet the specific requirements of a given application.

Feature	Benefit
Precision manufactured	Ensures accurate alignment and optimal bearing performance
Corrosion-resistant	Suitable for harsh environments and applications involving fluids
Easy to install	Simplifies maintenance and alignment adjustment

6-8 Effective Strategies, Tips and Tricks

Use dial gauges or laser alignment systems for precise shaft alignment.

Choose shims from reputable manufacturers to ensure quality and reliability.

Consider using laminated shims for applications requiring frequent adjustments.

Inspect bearings and shims regularly to detect any wear or damage.

Store shims in a dry, controlled environment to prevent corrosion.

Common Mistakes to Avoid

Incorrectly measuring shaft alignments can lead to premature bearing failure.

Overtightening shims can damage bearings and shafts.

Using shims that are too thick or too thin can compromise alignment accuracy.

Neglecting regular maintenance can result in increased vibration and noise levels.

Caring for Bearing Shims

Handle shims with care to avoid bending or damaging the edges.

Clean and lubricate shims before installation to prevent contamination and reduce friction.

Always refer to the equipment manufacturer's specifications for proper shim selection and installation procedures.
