Can ball screws be used in vertical applications without back driving?
No. Without a brake motor, ball screws will always back drive.
For vertical motion, lead screws can be self-locking so that even without brakes, dropping or drifting when motor power is removed or lost can be prevented. But the higher friction of a non-backdriving screw requires increased power to drive. The lead of the screw needs to be less than one-third of the minor diameter to not backdrive.
Speeds up to 5.5 meters per second.
Specially designed guide wheels using all stainelss steel components, heat stabilized material, and with special grease (Krytox GPL 227) can operate up to 500°F.
Between 0.005 — 0.02 when operated on DualVee track.
Axial load is any load that is parallel to the axis of rotation of the bearing.
Pitch describes a vehicle's tendency to rotate forward or backward.
