Ball-screw rigidity is a matter of definition
ball circle typically has higher rigidity and equivalent calculated life than a double nut, yet occupies a smaller envelope and costs less. Overall system stiffness considers not only nut stiffness but also that of the ball-screw shaft and support bearing: Shaft stiffness keys to Young's modulus

Bearings take the heat
had solidified the grease. A graphite-based dry lubricant better tolerated the high temperatures but made bearing balls skid and damage the race. The ball bearing was eventually replaced with a graphitemetal solid bearing and the problem went away. Graphite-metal bearings can survive temperatures
