  • Rotary Actuators
    as high as 500,000 lb-in. Helix actuators have helical grooves in the piston rod that convert linear to rotary motion. Helical actuators are available with standard rotations varying from 100 to 370° with outputs to 15,000 lb-in. A relatively new actuator gaining wide acceptance uses double helical
  • Toward the Instant-On Actuator
    It is important to understand what factors can delay the turn-on of devices that employ electromagnetic action. A typical magnetic-solenoid actuator is axisymmetric, because it has a central axis around which all its parts are revolved, including its cylindrical plunger armature made of solid steel
  • Using Linear Shaft Motors in Parallel
    and installation of the device very simple to do. Well that is true of all cylindrical non-contact linear motors; however, what makes the Linear Shaft Motor any different from them?. There is one more major issue that could cause force differences in any non-contact linear motor, that is sine error. What is Sine
  • Linear Feedback Devices Control Motion Precisely
    resistance. Other surface coatings serve to make the scale more durable. A linear variable differential transformer (LVDT) is a rugged noncontact electromechanical device with a movable central magnetic core, surrounded by cylindrical coils. It produces an ac output proportional to the core's
  • New Spins on Bearing Technology (.pdf)
    . The Robert C. Byrd Green Bank Telescope, the largest, fully steerable radio telescope in the world, was dedicated after 10 years of design and construction. Hollow-cylindrical bearings, rolling-ring linear actuators, and self-aligning bearings are some of the topics covered in this bearings reference
  • Which Screw? Picking the Right Technology
    is involved in making the best screw selection as it relates to electro-mechanical actuation. So, just what is a screw mechanism? A screw mechanism provides the means to produce linear motion by the rotation of either the screw or nut in an assembly. The screw is a cylindrical element upon which
  • Segmented bearings overcome limitations in conventional geometry
    Hollow-cylindrical bearings, rolling-ring linear actuators, and self-aligning bearings are some of the topics covered in this bearings reference guide. Edited by Lawrence Kren and Victoria Reitz Segment technology assembles a number of individual, self-contained segments to form a ball-bushing
  • When precision bearings are exactly right for motion control
    Motion Control. Linear actuators achieve precision motion control with little to no backlash. Using Linear-Shaft Motors in Parallel. Selecting and Applying Clutches and Brakes. Advertisement.
