August 10, 2010 - Bochum - So the portion of the machine-builders using electric linear actuators at the machines increased from 3.5% to 19%.
Linear actuators produce a straight-line resp. translational motion. So e.g. the hot glue nozzle of a packaging machine can be guided straight-lined across a paper web. However, the most common drives are rotary drives producing a rotary motion. Linear actuators cannot simply substitute rotary drives since they require an adapted construction of the machine.
In 2001, as the portion was still 3.5%, a readiness of the machine-builders already showed up to use increasingly electric linear actuators. However rather other translational drives such as ball screw, pneumatic or hydraulic linear actuators than rotary drives should be substituted.
5 years later, in 2006, the portion of the machine-builders with electric linear actuators was quadrupled from 3.5% to 13.6%. To 2010 this portion are to increase from 13.6% to 19%. At the same time the number of such linear actuators per machine is to increase to 1.1 on the average in 2010.
This article is published in the Quest Trend Magazine on http://www.quest-trendmagazin.de/Linear-actuators-grow-until-20.46.0.html?&L=1.
The trend to electric linear actuators is based on market surveys of Quest TechnoMarketing, Bochum, London in the years 2001, 2006 and 2007. Interviews with machine-builders in selected sectors were carried out. The results are representative since these interviews covered from 20% to 48% of the machine-builders in these sectors.
