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 [...]
The truth about actuator life: Screw drive survival
How do you determine the life of a screw actuator and make comparisons that are truly “apples to apples?” While the fatigue life of a screw actuator is heavily influenced by the load being applied to its rolling components, screw life also can be affected by wear, corrosion, contamination and other dynamic elements such as [...]
