Roller rail guides: Three reasons why you should use them

January 14, 2015 By Danielle Collins 1 Comment

Roller rail guides, which use cylindrical or barrel-shaped rollers instead of spherical balls for the load–bearing elements, are typically associated with machine tool applications. But the performance benefits that rollers bring to machining centers can be worthwhile in other applications as well. If you’re designing a machine or system that requires linear motion, consider these […]

Inertia Matching: Why Perfect Isn’t Always Best

December 30, 2014 By Danielle Collins 9 Comments

Newton's Cradle

Inertia matching is one of the inexact sciences of motion system design. When a motor and a load are coupled together, the ratio of load inertia to motor inertia determines how well the motor can control the load during acceleration and deceleration. In theory, a “perfect” inertia match of 1:1 (load inertia equals motor inertia) should […]

Five Ways to Make Your Linear System Cleanroom Friendly

December 19, 2014 By Danielle Collins 3 Comments

Cleanroom

Implementing linear motion in a cleanroom presents a particularly difficult challenge, since motion – whether rolling or sliding – necessarily produces particles. But by understanding the sources that contribute to particle generation and implementing smart design options, it is possible to achieve linear motion without compromising even the most stringent cleanroom environments. Below are five ways […]

Linear Motion in the Third Industrial Revolution

December 11, 2014 By Danielle Collins Leave a Comment

According to The Economist magazine, a third revolution is coming for the manufacturing industry, ushered in by 3D printing, new materials, and collaborative manufacturing services. Anyone who has watched the 3D printing industry develop over the past decade, or even the past five years, will likely agree. Gartner forecasts that worldwide shipments of 3D printers […]

Linear Motor vs. Ball Screw

December 2, 2014 By Danielle Collins 1 Comment

While ironless linear motors have been used in semiconductor and electronic applications for more than a decade, they are still viewed by many designers and OEMs as “niche” products. But the perception of linear motors as a costly solution for unique applications is slowly changing, as more industries are adopting them as replacements for ball screws […]

Make no mistakes about ball screw lead error

November 21, 2014 By Danielle Collins 2 Comments

Updated July 2016 || Accuracy is an important criteria in ball screw selection. But with two production methods and four different standards governing ball screw accuracy, making the best selection for your application can be a challenge. Understanding these standards and terminology, as well as the differences between the two manufacturing methods, will help you choose a ball screw […]
