Roller or Ball screw
Roller or Ball screw
(OP)
Hello everyone,
I'm planning a lilnear driving transmission and I can't decide between using roller or ball screw.
The system is planned for rough enviroment with heavy shocks.
Regarding the numbers. Both of them fits well and have safety factors (2.4 for ball and 6 for roller).
My fears are that althogh the s.f. the ball screw is delicate and won't stand it for long.
Is anyone has experience regarding those two? Or could anyone enlighten me?
Does the roller screw have secret advantages (exept heavy load capacity)?!
Thank you,
Lior G.

I suggest you contact application engineers at several such manufacturers and ask them to check your calculations and make suggestions for improvement.

do you knoe something regarding its tendancy to stuck or damaged due to shock loads?

If you have reversing loads and/or require low backlash, then a planetary roller screw would probably work better than a recirculating ball screw.
Hope that helps.
