ballscrew efficiency

[medo79]

Is it possible that the forward (drive) ballscrew efficiency is equal to backdriven efficiency?

Here is some technical information from Nook Industries that maybe of assistance.

Many thanks. However, this link doesn't show if the effecifiency is cinstant in forward and backdriven direction.

Thk's link shows seems to show that they are nearly the same:

Back driving efficiency = 2 - 1/efficiency

See SKF ballscrews catalogs technical data.
