Demystifying Ball Spline Specs
Place a recirculating-ball bushing on a shaft and what do you get? Frictionless movement of the shaft. But, create grooves along the axial length of the shaft that correspond to the radius of the bushing’s ball elements and you’ve got frictionless linear movement coupled with two important characteristics – those being anti-rotation torque transfer and [...]
Factors To Consider When Choosing An Actuator of Four Feet Or Less
Whether for packaging, life sciences, office equipment or factory automation, smooth motion, fast accelerations and a high degree of accuracy are hallmark requirements for linear movement actuators. Increasingly, miniaturization has added the additional requirement of compactness. One system that can meet all of the above requirements in its conversion of motor torque to linear thrust [...]
Factors To Consider When Choosing A Crossed Roller Bearing
For the lack of the right bearing, the kingdom of ever-faster microprocessors might have been lost. But this story has a happy ending. Technical achievements in microprocessor manufacturing, diagnostic equipment and automation have demanded increasingly more precise motion control. Whether it’s wafer positioning for the efficient manufacture of ICs, pick and place, vision inspection, parts [...]
