2. 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.

3. Roller screw - Wikipedia

   en.wikipedia.org/wiki/Roller_screw

   Planetary roller screws are used as the actuating mechanism in many electromechanical linear actuators. Due to its complexity, the roller screw is a relatively expensive actuator (as much as an order of magnitude more expensive than ball screws), but may be suitable for high-precision, high-speed, heavy-load, long-life, and heavy-use applications.

4. High performance positioning system - Wikipedia

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

   A typical linear recirculating bearing rail, of a high performance positioning stage, has a stiffness on order of 100-300 N/um. Such a performance is required in semiconductor process equipment, electronics assembly lines , numerically controlled machine tools , coordinate-measuring machines , 3D Printing , pick-and-place machines , drug ...

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. NTN Corporation - Wikipedia

   Other products that the company manufactures include heavy goods vehicle products, high precision ball, roller or needle, and combined bearings, linear motion, maintenance, and mechatronic products, range extensions, self-aligning bearing units, timing products and transmission seals. [29]

7. Air bearing - Wikipedia

   Examples of the benefits are: linear drives with accelerations of more than 1,000 m/s 2 (100 g), or impact drives with even more than 100,000 m/s 2 (10,000 g) due to high damping in combination with dynamic stiffness; sub-nanometer movements due to lowest noise-induced errors; and seal-free transmission of gas or vacuum for rotary and linear ...
