  • Pneumatic or servo?
    , but also their speed and acceleration while they travel to their final destination. There are many actuator types to consider when replacing a pneumatic system with a servocontrolled system. Actuator types available include electric cylinders with ball screws, rodless actuators with belts
  • Right-sizing pneumatic valves
    Determining flow capacity is a critical factor in valve selection. Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and countless other applications
  • The basics of pneumatic control valves
    positions are required. Four-way, two-position valves have four or five ports with two or three positions. A two-position valve has two distinct flow paths in each position to actuate and reverse cylinders, rotary actuators, or bidirectional motors. The spool directs flow from the pressure port while
  • Avoiding the runaround with direct-drive rotary motion
    Here's a look at the pros and cons of various direct-drive rotary systems. Manager Danaher Motion Wood Dale, Ill. Frameless DDR motors are best suited to high-performance applications where space is limited or weight is critical. Housed DDR motors are best suited for use on machines that do
  • Pneumatic linear guides lighten loads
    strength. Pneumatic SHP Rail Bearing Slides from PHD Inc. provide smooth, precise movement within confined spaces. Designed for light loads, the XLT guided cylinders from Parker Hannifin Corp. provide precise, torque-resistant linear motion. Linear-motion devices abound in automated assembly
  • Interactive designer configures pneumatic systems
    New engineering tools and components speed pneumatic-system design and boost productivity. An online Interactive Designer aids in sizing and selecting Bosch Rexroth's Rexmover rodless cylinders. The program also handles standard cylinders, shock absorbers, rotary actuators, and clamping devices
  • Closed-Loop Pneumatic Control In A Compact Package
    electrical servomechanisms and temperamental electro-mechanical ball-screw actuators. The system accurately stops and holds the rod in any position and is designed to control both linear and rotary pneumatic position-feedback actuators. The PCS accepts a 0 to 10-Vdc, 0 to 20-mA, or 4 to 20-mA
  • Linear actuators get a servo look
    in direct- drive linear actuators is called a tubular linear actuator. It evolved from linear-motor technology. A conventional way to describe a linear motor is to envision a rotary servomotor sliced lengthwise and then flattened. Motion between stator and what was formerly the rotor will now
