Screw actuators: characteristics and use

Screw actuators are very compact precision systems that are incorporated in a loadbearing frame in a U-profile:

  • a linear guide to support weights
  • dedicated ball screws to counteract axial thrust and determine position
  • pair of angular contact bearings for the screw support

Maximum compactness is due to the slide that incorporates:

  • recirculating ball screws
  • guide recirculating balls
  • the upper part is complete with holes to directly fasten the moving element

Ball screws are provided in various pitches to suit different applications, for example:

  • recirculating ball screws with a short pitch for high positioning precision
  • recirculating ball screws with a long pitch for high speed and acceleration

IKO, NSK, Kuroda and PMI provide screw actuators in various configurations and specifications. Screw actuator components are generally available from factory stocks. Once configured, actuator components are cut to size, processed and assembled within reasonable timescales to meet customer requirements.

Consult our catalogues to view miniature guides, guides with recirculating balls, splined shafts, ball bushings and components for any application.

Our commercial department is available to respond to any request. Contact us and we will guide you on the correct choice for your requirements, advising you on the best component and brand in terms of precision, performance and duration for a specific application.

Fluid Power Home / Products / Fluid Power Fluid Power Pneumatics Pneumatics technology utilizes compressed gas to generate mechanical motion. In pneumatic systems, air is directed to the required point through valves, in the form of compressed air. The stored energy in the compressed air is then converted into kinetic energy, enabling controlled movements, such as the... Read more →
