Ball Screw Vs Roller Screw

[Mohammad Arghavani Khoub 0]

Hi guys

I want to make a precision cartesian stage to use in optical imaging field . It should be low vibration and high precision in long life with high cycles.

My system is low load and place in good condition .

Ball screw or roller screw? which of one of them is more suitable for me.

THK to your guidance.

I suggest that you talk to the application engineers at your proposed vendors that you will buy this system from.

I would definitely head for the roller screw option - they completely eliminate backlash which - for your apparent application - would be very important.

The above said, I agree strongly with DrD....discuss with your suppliers and bear in mind that their answers will be loaded heavily to get you to buy; not necessarily what is best for you, but what will be best for them. If you always have that at the back of your mind, it should enable a good, informed decision.

Good luck!
