A Pitman arm is a shaft that translates rotary or angular movement into linear movement, or vice versa. Pitman arms are commonly found in water pumping windmills, automotive steering systems, and sewing machines. In windmills, the Pitman arm connects the driving gear to the pumping arm. It translates the rotary power from the wind blades to the ...
Steering system showing drag link. A drag link converts rotary motion from a crank arm, to a second bellcrank, usually in an automotive steering system.. While the origin of the term is not clear, it pre-dates the automobile, and is described as in use in 1849 as a means of rotating a Ducie cultivator being operated by cable by stationary steam engine (or between engines).
The recirculating ball steering mechanism contains a worm gear inside a block with a threaded hole in it; this block has gear teeth cut into the outside to engage the sector shaft (also called a sector gear) which moves the Pitman arm. The steering wheel connects to a shaft, which rotates the worm gear inside of the block.

Cornelis took out a patent on his sawmill on 15 December 1593, and on the pitman arm device on 6 December 1597. [citation needed] Early sawmills adapted the whipsaw to mechanical power, generally driven by a water wheel. The circular motion of the wheel was changed to back-and-forth motion of the saw blade by the pitman arm or rod. A pitman is ...
The idler arm supports the end of the center link on the passenger's side of the vehicle. The idler arm bolts to the vehicle's frame or subframe. Generally, an idler arm is attached between the opposite side of the center link from the Pitman arm and the vehicle's frame to hold the center link at the proper height. Idler arms are generally more ...
