  action. Horizontal movement must synchronize closely with the vertical action of the vacuum heads (produced with air cylinders). The combination of intermittent and reciprocating motions, especially at high speeds, puts a significant load on the drivetrain components. "We needed to position a coupling...
• Hydraulic squeeze bushings lets shafts slide, lock, and slide
  of applications, especially machine tools. Type ASA squeeze bushings only resist axial forces. They are commonly used in fixturing and reciprocating shaft applications. For instance, a shaft might firmly hold a workpiece in place on a table until the part is machined. Removing pressure from...
• New Technology for Metering Fluids in Medical Devices
  10:1to as high as 1000:1 on some pump models. Accuracy, repeatability, and linearity across the turndown range are the features that differentiate a metering pump from a typical positive displacement pump. Positive displacement metering pumps are normally classified as rotary or reciprocating. Rotary...
• Vacuum and Pressure Handbook: Air Compressors
  because of its high pressure capabilities, flexibility, and ability to rapidly dissipate heat. of compression. And it is oil-less. Compression is accomplished by the reciprocating movement of a piston within a cylin-. der (Fig. 12). This motion alternately fills the cylinder and then compresses the air...
• WILDEN AODD: PUMPS THAT SET A HIGH STANDARD
  industries such as food, pharmaceutical, chemical, oil and gas, waste treatment, etc. How it Works. Wilden AODD pumps are classified as reciprocating, positive-displacementstyle pumps. The pump operates by displacing fluid from one of its two liquid chambers upon each stroke completion. To operate...

• Rolling-ring linear actuators put friction to work
  . Rolling-ring devices instead use a "free-movement" lever to un-load compressive ring-shaft forces to permit effortless manual positioning. This helps cut downtime for setup and changeover. Nonreciprocating models are ideal for indexing, materials handling, and X-Y table positioning. Reciprocating...
• Five Questions to Ask when Specifying Fluid-Handling Pumps
  reciprocating motion at the diaphragm, and check valves control flow into and out of the pump chamber. Designed without rotating or sliding seals, the pumps are particularly suited for applications requiring contamination-free pumping, corrosion resistance, and long service life. Diaphragm pumps can...

• Plastics that don't wear out their welcome
  . For example, structural variables include materials in relative motion and their surface finishes, as well as interfacial materials such as lubricants and abrasive particles. Another factor is the type of motion -- reciprocating versus continuous or geometrical motion (i.e., sliding, rolling) between...
