A spiral movement can be facilitated by rotary and linear motions. A combination of these motions allows accurate and sophisticated positioning. THK's "Ball Screw Spline" has Ball Screw nuts and Spline nuts on a single axis to allow both rotary and linear motions from one compact design.

Scalar robots are used to transport and position workpieces within small areas. LM Guide systems are crucial for their high accuracy in both stroke movement and rotation on the Z axis, where high speed and low runout are essential.
