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. Rolamite - Wikipedia

   en.wikipedia.org/wiki/Rolamite

   The Rolamite bearing has very little friction. A Rolamite is a technology for very low friction bearings developed by Sandia National Laboratories in the 1960s. [1] It consists of two cylindrical rollers held captive in a channel by an S-shaped metal strip. The strip is under tension, which keeps the rollers pressed together with the strip ...

5. 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 ...

6. Pacific Bearing Company - Wikipedia

   en.wikipedia.org/wiki/Pacific_Bearing_Company

   Its first bearing product was a line of self-lubricating bearings; [4] the company also manufactured bushings, thrust bearings, and skid plates, and continued to produce custom parts. By the turn of the century, Pacific Bearing had reciprocal trade agreements with manufacturers in Japan and Europe, expanding the range of products it could offer ...

7. Linear motor - Wikipedia

   en.wikipedia.org/wiki/Linear_motor

   Linear motors are commonly used for actuating high performance industrial automation equipment. Their advantage, unlike any other commonly used actuator, such as a ball screw, timing belt, or rack and pinion, is that they provide any combination of high precision, high velocity, high force and long travel. Linear motors are widely used.

   The FDA has granted 510(k) clearance to Abiomed Inc's (NASDAQ: ABMD) Impella Low Profile Sheath. Compared to the existing 14 French (Fr) sheath used for the placement of Impella CP, the new sheath ...

9. Air bearing - Wikipedia

   en.wikipedia.org/wiki/Air_bearing

   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 ...
