This conventional double nut has a split spacer that can be removed for grinding to adjust the preload. Fitting keys prevent the nuts from turning relative to each other. The size of the nuts, mainly ...

Not all ball-screw makers spec products the same way. Stiffness or rigidity is a key factor in evaluating ball-screw drives for specific needs. Rigidity, in this context, describes a ball screw's ...

Ball screw drives with preloaded nuts are frequently used in machine tools. They are typically exposed to rather high load forces and must be in addition preloaded for high precision requirements. An ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

Ball screw mechanisms represent a critical class of precision drive components that convert rotational motion into linear motion by utilising recirculating ball bearings. This conversion is achieved ...
