Do ball screws have backlash
Did you know?
Non-precision gear couplings use backlash to allow for slight angular misalignment. However, backlash is undesirable in precision positioning applications such as machine tool tables. It can be minimized by tighter design features such as ball screws instead of leadscrews, and by using preloaded bearings. A preloaded bearing uses a spring or other compressive force to maintain bearing surfaces in contact despite reversal of direction.
