Abstract :
Linear motion technology has traditionally occupied a defined market niche and often plays a supporting role to conventional fluid power systems. Continuous developments in technology are, however, blurring the lines between linear motion, pneumatics, and hydraulics. As a result, machine and plant designers, builders and operators now have a far wider range of options for moving and positioning parts, assemblies, and mechanisms. Fluid power has been used as a source of movement, positioning and control for many hundreds of years. However, the latest developments in electrically driven linear motion technology look set to offer a viable alternative to the use of hydraulic and pneumatic devices.
