Even with the most-sophisticated motion controller, designers can still find it difficult to attain precise linear ... from load-bearing to nonload bearing zones in the runner block.

Crossed-roller linear bearings do require cages to keep their rollers evenly spaced and prevent jamming. In fact, the cages in any bearing prevent ball-to-ball or roller-to-roller contact ...

The function was integrated into linear recirculating roller bearing and guideway assemblies in 2017 and is now also available for linear recirculating ball bearing and guideway assemblies. The ...

Stewart platforms typically use six electric or hydraulic linear actuators to provide ... the resistive touch screen and registers the ball bearing’s location. Then a PID compares this to ...
