Mastering Ball Screws Pt. 2: Ball Screw Preloads

Preloading is used to increase the feed accuracy and rigidity of ball screws. Why is this necessary? In many applications utilizing ball screw actuation, position accuracy is of utmost importance. With many ball screw driven actuators, position accuracy can be achieved ...

Mastering Ball Screws Pt. 1: Steel Ball Recirculation System and Characteristics

Ball screws are one of the many components seen throughout factory automation applications. Using the same concept seen with a bolt and nut, this assembly uses the rotary motion of the screw to actuate the nut in a linear direction. ...

Part II: Application Examples to Illustrate Ball Screw Selection

Introduction to Ball Screws The main function of a ball screw system is the efficient transfer of rotational motion to linear motion, sometimes to extremely high degrees of precision, accuracy, and repeatability.  Ball screws are typically differentiated by the manner ...

Part I: Comparing Rolled Ball Screws and Ground Ball Screws

At a high level, ground and rolled ball screws appear to function nearly identically within a wide range of mechanical applications.  However, the raceway surfaces, which are very similar to traditional machine screw threads found in a typical screw/nut system, ...

Strengths & Limitations: Belt Drive vs. Ball Screw Actuators

The challenge for mechanical automation systems in the past has been the successful conversion of rotational motion from electric or mechanical motors into useful forms of linear motion.  A breakthrough in this regard, the conveyor belt system represented one of ...

Designing with Single Axis and Multi-Axis Actuators

The principles of linear motion are hundreds of years old. Throughout the years, the general principles of linear motion have never wavered, while the technology has made significant advancements to yield more precisely controlled motion and greater flexibility of the ...
Selecting Actuators

Size Does Matter…

Dear MISUMI Engineering Team: We have several linear motion setups in our production line, with a variety of actuators. We’ve experimented with belts, ball screws, and lead screws in the past, but haven’t been able to find something that always ...
