Racks are commonly used with a pinion - a spur gear. The combination of the two convert rotary motion into linear motion.
Both the rack and the pinion have straight cut teeth.
Example uses of rack and pinion gears are to open the flap gates on canal lock gates, in the steering mechanism of cars, and cog railways.
We can manufacture racks to any pitch.
