What are feeler gauges and how are they used?
Feeler gauges are mechanical measurement instruments used to provide a precise reading of the gap between two parallel surfaces. They are typically sold as a set, with each set consisting of a series of dimensionally accurate pieces of shim stock that are joined using a common shaft and nut or riveted connection.
Feeler gauges are commonly used in industries such as aerospace, automotive, pharmaceutical, oil & gas, and general industrial machining.
What are some applications of feeler gauges?
Feeler gauges are used to check flatness and gap between mating parts. They are commonly used in the automotive industry to set the valve clearance between the rocker arms and the valve stems. In the aerospace industry, feeler gauges are used to measure the clearance between turbine blades and the blade ring.
Feeler gauges are also used to check or verify the accuracy of parts such as their dimensions and shapes.
How do feeler gauges ensure accurate measurements?
Feeler gauges provide precise readings of gaps, allowing for accurate measurements of small gaps that may be difficult to measure with other tools. They can be used in tight spaces where other measuring devices may not be able to be employed.
Feeler gauges also provide consistent and repeatable results, ensuring that measurements are consistent among operators.
Additionally, feeler gauges are versatile and can be used in a wide range of industries and applications.
How do feeler gauges differ from other measuring tools?
Feeler gauges are specifically designed to measure gaps and clearances between two parallel surfaces, whereas other measuring tools like calipers and micrometers are used to measure dimensions like length, width, and thickness.
Feeler gauges are made up of a series of progressively smaller, thinner blades that can be slipped into thin gaps to measure the exact dimension of the gap.
This allows for precise measurements in very small, tight areas.
Where can I purchase high-quality feeler gauges?
There are several options for purchasing high-quality feeler gauges. You can find them on websites like Amazon, Thomasnet, DirectIndustry, and Thread Check. It is recommended to compare prices and features of different brands and suppliers prior to buying.
How should I maintain and store my feeler gauges?
To maintain your feeler gauges, keep them clean and free of any residue that may impact their accuracy. Lubricate the blades with a light oil to prevent rust and ensure smooth operation. Avoid bending or twisting the blades, as this can affect their accuracy.
When storing your feeler gauges, keep them in a dry, clean place to prevent rust and other damage.
Store the blades together in their original set to prevent loss or damage to individual blades.
Use the protective case or holder that comes with the feeler gauges to prevent them from becoming bent or misaligned.
Avoid storing them in extreme temperatures or humidity, as this can cause damage or rust.
