There are three main types of table saw inserts: zero-clearance inserts, dado inserts, and standard inserts. Zero-clearance inserts provide support for the wood being cut, dado inserts are used for making dado cuts, and standard inserts are used for general cutting tasks.
That usually refers to the part of a standard transmission that inserts into the crankshaft pilot bearing or bushing.
Main bearings
The main bearings support the crankshaft.

A main bearing bore refers to the cylindrical opening in an engine block where the main bearings are housed. These bearings support the crankshaft and allow it to rotate smoothly, reducing friction and wear. The bore's size and precision are critical for engine performance, as they affect the alignment and clearance of the crankshaft. Proper maintenance and machining of the main bearing bore are essential for the longevity and efficiency of the engine.
A precision straight edge and a feeler gauge would typically be used to check the straightness of a crankshaft. The straight edge is placed along the length of the crankshaft to visually detect any deviations, while the feeler gauge is used to measure any gaps between the straight edge and the crankshaft surface.
Orthoses refer to the specially designed foot inserts that align, improve or support the function of a foot.
Arch support inserts are a valuable tool for many people who have flat people. For the best possible fit, I recommend visiting a professional podiatrist for their advice.
There are many products on the market that help ease pain in the bottom of your feet. I was at a shoe store recently and different types of inserts were offered for different types of uncomfortable pain. It is very possible that some of these inserts are for arch support.
