Lead Screw diameter for lifting 200Kgs

[Rajashekar]

Hi
I one of my application i am using the lead screw arrangement to lift 200kg weight using handle
I used trapezoidal thread and nut.
Could anybody suggest the diameter required for lifting the weight of 200kg

Look up "Nook industries", They make lots of lead screws, and would have specs for them... Depending on the length (for rigidity) 1" / 25mm would be a good starting point

Thomson Linear is another

Definitely look up recommendations and specifications from a good supplier. If you want to lift the load once you can get away with a much smaller screw diameter (and therefore smaller thread area), at the cost of rapid wear out.

Thanx, I will look into that and get the specifications and will get back if I need some more details
