Planetary Roller Screws: The Crown of High Precision Transmission
Planetary Roller Screw (standard type) is a transmission mechanism that combines helical motion and planetary motion to transform the rotary motion of the screw into the linear motion of the nut. Planetary Roller Screws have the characteristics of strong load carrying ca...Read more -
Roller Screw Actuators: Design and Applications
Electromechanical actuators come in many varieties, with common drive mechanisms being lead screws, ball screws, and roller screws. When a designer or user wants to transition from hydraulics or pneumatics to electromechanical motion, roller screw actuators are usually t...Read more -
Methods For Increasing Accuracy In Stepper Motors
It is well known in the engineering field that mechanical tolerances have a major effect on precision and accuracy for every type of device imaginable regardless of its use. This fact is also true of stepper motors. For example, a standard built stepper motor has a toler...Read more -
Ball Screw Linear Actuators
For higher duty cycle and faster thrust loads, we suggest our Ball Screw series of stepper linear actuators. Our Ball Screw Actuators are able to carry heavier loads than other traditional linear actuators. The ball bearings help to improve the speed, force, and duty cyc...Read more -
Is Roller Screw Technology Still Underappreciated?
Even though the very first patent for a roller screw was granted in 1949, why is roller screw technology a less recognised option than other mechanisms for the conversion of rotary torque into linear motion? When designers consider the options for controlled linear motio...Read more -
Ball Screws Principle of Operation
A. The Ball Screw Assembly The ball screw assembly consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves providing the only contact between the nut and the screw. As the screw or nut rotates, the balls are deflected...Read more -
Linear Motion Systems for the Medical Industry
Motion control is critical to the proper function of many types of medical equipment. Medical equipment faces unique challenges that other industries do not, such as operating in sterile environments, and eliminating mechanical disruptions. In surgical robots, imaging eq...Read more -
Actuator Applications in Automation and Robotics
Let's start with a quick discussion of the term "actuator." An actuator is a device that causes an object to move or operate. Digging deeper, we find that actuators receive an energy source and use it to move objects. In other words, a...Read more
