Precision Medium-Large Industrial Actuators


There are 8 standard Rolaram linear actuator models, available in 2 standard drive configurations.

Load capabilities range from 4kN to 400kN. Available with roller screw drive in models R050, R075, R100, R125, R150, R175, R225 and R250. Where accuracy and/or duty is less important they are available in a ball screw version. Custom designs are available.


  • Right angle, Parallel or In-Line drive configurations
  • Roller Screw versions R075, R100, R125, R150, R175, R225 and R250
  • Ball Screw version for B050, B075, B100 and B125
  • Choice of end fittings: Clevis, Threaded End, Top Plate, Fork End, Rod End
  • Trunnion mounting (with or without feet)
  • Rear Clevis or Fork End
  • Limit switches (Proximity Sensor or Electro-Mechanical)
  • Encoder (Absolute or Incremental)
  • Guided RAM (Anti-Rotation Mechanism) version available

The Rolaram linear actuator concept has been successfully applied in many varied ‘special’ applications, requiring for example:

  • Very high linear speed, over 50 metres/minute
  • Very high dynamic load, over 1000kN
  • In-line drive configuration
  • Auxiliary Drive Units
  • Temperature extremes or hazardous environments such as subsea
