  • How To Size a Ball Screw
    Ball Screw Selection Example. Specification: Equipment: Transfer Table Screw Orientation: Horizontal Load Supported on Dove Tail Ways: .20 Coefficient of friction Load is 2500 lbs. Max (combined weight of product and table) Stroke Length: 38" Travel rate: 600 inches per minute (Max.) Input RPM
  • Have ball screws become a commodity?
    on a threaded shaft. Balls recirculate in one of two ways: through external tubes that transfer the balls from one end of the nut to the other; or with internal deflectors that divert balls to the next thread or down the entire length of the nut. Ball screws with external-tube return systems cost less
  • Angle Joints and Ball Joints Create Movement
    such as cushioning, drawing, tilting, levering, etc. But that is not all. Housings, ball studs and Co. are as various in their geometry, appearance and construction as the ideas of the designers. There are standard parts in every possible size, construction and material composition available for most
  • Variables of Pin Transfer (.pdf)
    Pin transfer is a way of selectively depositing a semi-solid or liquid material (like a solder paste or ball-attach flux) onto a substrate. It is commonly used to apply flux to BGA (ball-grid-array) pads to promote subsequent solder sphere attachment. Pins are dipped into a reservoir of material so
  • Increase Productivity Through Vibration Packing
    this on one piece of equipment and would have the operator make the two transfers manually. SOLUTION: Our solution was to provide a flat deck vibrating table driven with an airpowered piston vibrator (explosion-proof by design). The table top was designed to house a set of air-powered ball transfers
  • Fluid Transfer Valves
    Fluid-handling devices are not basically concerned with the modulation of power, but only with the movement of fluid. Choosing a fluid-handling valve used to be easy, because each one had its own area of utility. For on-off, full, or no-flow requirements, ball and gate valves were favored; where
  • How to make bearings last in electric motors
    Creating the best possible operating environment lessens the chance of premature bearing failure. Here are some basic guidelines. A deep-groove ball bearing installed on the output shaft of an acinduction motor. The motor end cap supports the bearing outer race. Characteristic fluting caused
  • Pick & Place Conveyor System
    of two conveyors, a transfer slide and lift/gripper mechanism similar to the diagram shown. Equip each conveyor and ball screw transfer mechanism with the Emerald Series SERCOS servo packages controlled by the EMC-2100 Emerald automation controller. Establish a communication link to the packaging
