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 amount of preload applied can be used to adjust the stiffness (and friction) of the bearing by changing the ball size to as small as 1 µm. Each application is a little bit different. For every ...

Schaeffler integrates sensors and vibration analysis into its linear guidance systems and offers these mechatronic components with automated relubrication. The function was integrated into linear ...

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 ...

Rotary Air Bearings provide High Precision Motion with Minimal Eccentricity and Wobble. The rotary air bearing on the left is non motorized – its low friction is apparent from the long time it keeps ...

Engineers and manufacturers are increasingly turning to robots for increased productivity, and key to these engineering marvels are linear guides. Martin Ahner, head of norelem ACADEMY, discusses the ...

CARY, N.C. (June 11, 2009) – MTS Systems Corp., Sensors Division has improved the design of its Temposonics linear-position sensors to increase the sensors’ longevity in high-vibration applications ...
