Technology Blog
In the last several postings we saw how a ball screw changed the rotary motion of the stepper motor to linear motion We calculated the rotational equivalent of a 200 pound linear load that was effectively reduced by the inverse square of the pitch or Calculating reflected inertia for linear
Ball and roller screws
Ball and roller screws turn rotary motion into linear motion and vice versa Product range Roller screws Diameters from 8 up to 240 mm Leads from 1 up to 50 mm Dynamic load capacity up to 3 994 kN For heavy loads with high dynamics and long life Read more Precision ball screws
Electric Actuators
A lead screw converts rotary motion into linear motion by combining a screw and a nut where the screw thread is in direct contact with the nut thread Lead screws are not as efficient as ball screws are but they are resistant to back driving Electric linear actuators are used to automate linear valves including globe valves gate valves
Del
Del-Tron Precision Inc was founded in order to serve the needs of automated equipment manufacturers for innovative high quality and reasonably priced anti-friction linear bearings For over 30 years we've manufactured linear motion products we've categorized into nine distinct family groups
FUNdaMENTALS of Design
Jan 17 2003A screw is essentially a rotary wedge: it converts rotary motion into linear motion by the action of the inclined plane of one thread on another If you walk up a spiral staircase the spiral staircase remains fixed but you rise up and turn as you walk up th e staircase The thread on a nut and a screw shaft are also helixes
Convert rotary motion into linear motion
Lead screws are a common technology used to convert rotary motion into linear motion and are often used to provide actuation to a set of linear bearings Plastic lead screw nuts are an excellent alternative to ball screws in many applications where extreme precision (micron level) is not required
Ball Screws
With superior accuracy repeatability and high efficiencies ball screws are the best way to translate rotational motion into linear motion Ball Screw Applications Ball screws are used in motion control but require bearing supports and motor couplings to work effectively

Actuators Ball Screws Lead Screws Couplings and more
Mechanical actuators convert the rotary motion of a control handle or knob into linear motion through attached gears or other configurations Ball screw or lead screw actuators produce motion by rotating a nut and moving a shaft linearly wheel and axle actuators rotate a
Can a bearing be used for both Linear and Rotational motion?
But between the ball retainer and the outer casing there are rotational ball circuits as well that allow the entire retainer and shaft to rotate within the stroke bush unit This is just one example of the various types of bearings that can combine rotational and linear motion
