The overall length of standard racks on the market is generally not more than 2000mm, and offered in 500mm units such as 500mm, 1000mm, 1500mm.Furthermore, the cross-sectional shape is often a square or rectangle, and some are round called round rack type.
The helix angle of a helical rack is set at 19 degrees 3142 by many rack manufacturers. When the helix angle is set like so, the movement when a pinion rotates (for instance one rotation) becomes an exact distance in mm, thus making it user-friendly.
