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 Drives
Linear Motor vs. Ball Screw
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
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 […]
Three Ways to Save Space with Linear Actuators
Linear actuators are available in configurations that address virtually any application – rail, shaft, or cam roller guideway; screw, belt, or linear motor drive; with or without protective covers; and a wide variety of features to meet unique environmental or technical requirements. All these options make it relatively easy to find the right actuator for […]
How Seals Extend the Life of Linear Systems
When selecting a linear system – ball screw, linear guide, or actuator – most of the focus is on application data such as load, speed, travel, and duty cycle. But there’s another factor that should be considered, especially for technically demanding applications or harsh environments. That factor is sealing. How are the bearings protected against […]
How to Achieve Long Travel and High Speed with Ball Screws
If you need a linear motion system that can travel at high speed over long lengths, what solutions come to mind first? Belt drives? Rack and pinion systems? Linear motors? If the application requires high thrust force, belt drives won’t suffice, and if high positioning accuracy is important, rack and pinion systems are out. Linear […]
Linear Drive Offers Option for Automatic Shaft Cleaning and Lubricating
Aston, Penn. – For automatic cleaning and lubrication of the drive shaft, Uhing linear drives are now available with a combination shaft scraper/grease fitting option. The addition removes excessive grease, dust and dirt from the shaft while the drive is running and simultaneously assures adequate shaft lubrication. As debris accumulates at either end of the […]
