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.
A dial indicator is commonly used to check a crankshaft for wear. This precision tool measures the crankshaft's runout and any deviations from its intended specifications. By placing the dial indicator against the crankshaft at various points, technicians can identify wear patterns and determine if the crankshaft is still within acceptable tolerances. Additionally, micrometers can be used to measure the diameter of the journals for further assessment of wear.
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.
