• Straight talk on selecting linear actuators
  , 24, 90, or 180 Vdc or 110, 220, or 380 Vac. Electromechanical linear actuators give precise, efficient, accurate, and repeatable motion. They are a relatively maintenance-free alternative to hydraulic or pneumatic equivalents. Although every application is different, the selection process...
• Understanding mechanical limitations of linear actuators
  In many cases it is essential to understand the mechanical limitations of an actuator to successfully apply linear-motion devices. The following information provides an overview to help in understanding the nuances and limitations of linear actuators. Accuracy needs to be considered from two...
• Rotary Actuators
  100 . Torque is directly proportional to vane area and effective fluid pressure. Vane actuators have torque outputs as high as 500,000 lb-in. have helical grooves in the piston rod that convert linear to rotary motion. Helical actuators are available with standard rotations varying from 100 to 370...
• Electrohydraulic Actuators
  of these actuators is the feedback system. A number of different feedback systems, both mechanical and electrical, are used, depending on the accuracy and durability required. One method for accurately sensing cylinder rod position is with a linear displacement transducer. In one widely used system...
• Pneumatic linear guides lighten loads
  performs a wide range of pushing, stopping, and lifting functions. The HBT Series linear slide from Parker Hannifin Corp. is suited for applications that include material handling, packaging, assembly, parts transfer, and clamping. Pneumatic guiding cylinders from Rexroth Bosch Group have high torsional...
• Actuators that mimic nature
  of the cross-sectional area to produce matching forces. The Fluidic Muscle is connected to a lever. As the muscle contracts, the lever lifts and puts tension on the belt. Pneumatic actuators are commonly used for linear motion. Unfortunately they depend on moving parts and seals that make them susceptible to leakage...
• Rolling-ring linear actuators put friction to work
  , Acme, or leadscrews), pneumatic and hydraulic cylinders, and timing belts. Here, good designs minimize friction and compressive loads because these factors waste power, promote wear, and generate excess heat. But linear actuators built around a novel "rolling-ring" design from Amacoil Inc., Aston, Pa...
• Chrysler brings Ethernet to pneumatics
  structural parts. Pneumatics work together with electromechanical actuators to move and position parts. For instance, air knives help separate individual blanks from a stack, then gantry-mounted suction cups lift them onto a conveyor. The conveyor carries the blanks through a washer, where...
• Pneumatics ensures ultraclean packaging
  for filling and cleaning, inserts caps, and drives linear actuators for motion control. A DeviceNet fieldbus connects electronic controls, pressure switches, valves, and position sensors, and offers easy-to-decipher diagnostics. The easy-to-clean concept was a key consideration when selecting the pneumatics...
