2. High performance positioning system - Wikipedia

   en.wikipedia.org/wiki/High_performance...

   HPPS, driven by linear motors, can move at a combined high velocity on order of 3-5 m/s, high accelerations of 5-7 g, at micron or sub micron positioning accuracy with settling times on order of milliseconds and servo bandwidth of 30-50 Hz. Ball screw actuators, on the other hand, have typical bandwidth of 10-20 Hz and belt driven actuators at ...

3. Linear-motion bearing - Wikipedia

   en.wikipedia.org/wiki/Linear-motion_bearing

   A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings. Motorized linear slides such as machine slides, X-Y tables , roller tables and some dovetail slides are bearings moved by drive mechanisms.

4. Linear stage - Wikipedia

   en.wikipedia.org/wiki/Linear_stage

   Zaber motorized linear stage. A linear stage or translation stage is a component of a precise motion system used to restrict an object to a single axis of motion. The term linear slide is often used interchangeably with "linear stage", though technically "linear slide" refers to a linear motion bearing, which is only a component of a linear stage.

5. Way (machine tool element) - Wikipedia

   en.wikipedia.org/wiki/Way_(machine_tool_element)

   The geometry of the way can vary depending on the situation. The most common types are flat, vee, and dovetail ways. Flat ways are used when there is little requirement for the slide to be constrained perpendicular to the axis of movement, or the constraint is being provided by another component or otherwise not needed, such as on the carriage of a lathe.

6. Ball screw - Wikipedia

   en.wikipedia.org/wiki/Ball_screw

   A ball screw (or ballscrew) is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

7. Fluid bearing - Wikipedia

   en.wikipedia.org/wiki/Fluid_bearing

   Hydrodynamic bearings rely on the high speed of the journal (the part of the shaft resting on the fluid) to pressurize the fluid in a wedge between the faces. Fluid bearings are frequently used in high load, high speed or high precision applications where ordinary ball bearings would have shortened life or caused high noise and vibration. They ...
