      Hello all,

      Just posted a bit of a rant in the Calculations forum about this, but here goes again!

      I'm looking for an in-line Linear Mechanical Actuator which can lift a 8000N load.

      Space is at a premium, as the actuator should fit within a 150mm diameter tube...

      If anyone knows of a supplier of such an actuator, please can you let me know!

      Thanks in advance!

      You could easily do this with either hydraulics or pneumatics. 8000 N requires a pressure of 453KPa (66psi) with a cylinder of 150mm diameter. Even if you had to reduce the operational diameter to 120mm the pressure would only be 707KPa (105 psi) which is still well within the capabilities of standard shop air.

      I think a Lead screw of very low pitch connected to a 0.25 - 1 H.P. motor will be better in your case.
      Normally a 0.25 H.P. , flange mounted can be found in the market with diameter lesser than 150 mm. ad can be connected to the screw with the help of Love-Joy Coupling.
      The nut to be connected to the moving part and must be well guide in the vertical pipe.
      If the motor used is a 3 phase motor even up-down arrangement can be easily done just by a switch.

      I hope it works for you

      If you want to get linear actuator of approximately load capacity of 4000 lb then please let me know. Right now I don't have an actuator with 8000 N load.

      Pls why not speak in SI to ensure generality? These imperial units could sound vague atimes.
      I need an electric DC motor of 10hp or 7.5kW. Can I get it from you?

      Parker ETH electric cylinder

      You should look at the improved high force ETH electric cylinder by Parker. I just used one in a very tight space for high inertial loads and it worked very well. You can put either a stepper or a servo on it, and a gearbox if you need to.

      Try Tolomatic -

      Tolomatic has a fine selection of linear - electric actuators, both in ball screw and acme types.

      Have you looked at the Linak LA36?
