Ballscrew drives efficiently convert rotary motion to linear motion to provide smooth and accurate positioning of linear motion systems. Precision rolled ballscrew drives are available in a variety of metric sizes with nominal diameters from 16 - 63 mm and leads from 5 - 50 mm. Ballnuts are … [Read more...]
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 … [Read more...]
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 … [Read more...]
