WebbIn mechanical engineering, a key is a machine element used to connect a rotating machine element to a shaft. The key prevents relative rotation between the two parts and may enable torque transmission. For a key to function, the shaft and rotating machine element must have a keyway and a keyseat, which is a slot and pocket in which the key fits.

There are five main types of keys: sunk, saddle, tangent, round, and spline. Types of sunk keys: rectangular, square, parallel sunk, gib-head, feather, and Woodruff. Parallel keys are the most widely used. They have a square or rectangular cross-section. Square keys are used for smaller shafts and rectangular faced keys are used for shaft diameters over 6.5 in (170 mm) or when the wall thickness of the mating hub is an issue.

The centre of the pair should be opposite the keyway if a key is used with the set screws bearing on a slight relief turned in the shaft or a pair of flats. A single setscrew bearing on a shaft is bad practice and will not ... WebbKeyed Drive Rollers. 3" to 4" Roller Diameter. 5" to 10" Roller Diameter. These rollers are made of SBR rubber. Use them with a keyed shaft to prevent slippage in high-torque applications. Also known as contact wheels and feed rollers, drive rollers spin in unison with a shaft or stud to transmit power.

When properly manufactured, a total shaft-hub clearance between 0.0004 and 0.002" is adequate to ensure that minimal torque applied to the clamping screw will guarantee a high-force frictional clamp … the doyle kensington
