Rolamite bearings, originally designed for NASA with an order of magnitude of friction lower than ball bearings, can generate cog-free linear motion. A carriage is propelled along a track under the ...

These direct-drive Linear translation stages use linear motors and are designed with high load, high speed industrial precision automation in mind. The V-817 motorized translation stage family is ...

Low-friction, high-stiffness ball guides support on one rail (top) or two (bottom). The trade-offs for this performance are higher cost and more noise. The shortest path between two points is a ...

The OptiDrive BS25/55 is an alternative to the asynchronous linear motor drives used previously. With the new unit the contact pressure of the drive wheel is automatically set depending on the ...

Here’s a little engineering quiz for you: If an app needs to move a 500 kN axial load along a 1,500 mm stroke, is it best to use a roller screw or ball screw? If you instinctively said roller screw, ...

Several factors significantly influence the decision to use pneumatic or electric control in a linear motion control application. The obvious considerations include the technology preference in use at ...

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries Electric linear actuators are increasingly preferred over hydraulic and ...
