Flat Saddle

A Flat Saddle key is a rectangular piece of metal used in mechanical engineering to transmit torque between a shaft and a rotating element like a gear or pulley. It fits into a slot on the shaft and is fastened to the hub of the rotating element. This key allows for easy assembly and disassembly, accurate positioning, and distributes load over a larger area, reducing damage risks. Flat saddle keys are commonly used in industrial machinery, automotive components, and agricultural equipment for reliable and efficient torque transmission.
