What's the most popular type of linear actuator? Pneumatic. That's according to a recent survey of Design News readers. Some 57% of the respondents reported that they specify, buy, or approve pneumatic linear actuators. Other top options: Lead-screw driven (48%), belt driven (42%), and hydraulic actuators (42%). What's the most important factor in selecting a particular type of linear actuator or positioning system? Number one answer: That the product meets performance requirements. Vendors take note that pricing was number five on the list.
