Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

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 ...

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 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 ...
