Straight-sided splines have teeth parallel to the axis of linear motion or rotation, whereas the teeth on involute splines are angled, allowing for more gradual engagement between components.

A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom ...

To produce a high speed, load-bearing linear actuator today, many machine and equipment builders invest a good deal of time and money to design a mechanism with rotary-to-linear motion conversion.

Bearings allow rotation or linear movement while reducing friction. Ball splines enable linear motion and torque along the same axis. Each has its best-suited applications.

This system converts rotary motion to linear motion or vice versa. It consists of a circular gear (pinion) meshing with a straight gear (rack), commonly used in steering mechanisms and machine tools.
