igus has developed a new lead screw configurator that allows users to quickly design their own lead screw and associated drawing without in-depth technical knowledge and CAD software. Designing a lead screw usually requires significant effort for the user, who is required to have technical drawing skills and access to a CAD program. The new […]
Miniature linear translation stages in X, XY, and XYZ configurations
The new L-505 linear translation stage family from PI (Physik Instrumente) is available with integrated linear encoders providing 0.05 microns and 0.005 microns resolution, respectively. The new design allows for compact multi-axis assemblies, at affordable prices. Many motor and drive variations are available, from fast dc-servo motors with linear encoders and low-friction ball-screws to simple […]
igus belt drive actuator lowers automation costs
New lubrication- and maintenance-free toothed belt drive actuators from igus can significantly reduce the costs of automation tasks such as pick-and-place, inspection, and assembly applications. High speeds, high load and precise positioning accuracy are not required in every application, such as format adjustment and vision system positioning. Many solutions in the market are oversize, however, […]
Linear motor stage offers long travel, nanometer resolution
The new V-417.336025E1 long travel linear motor stage from PI (Physik Instrumente) features travel length of 32 in. (813 mm). The direct-drive stage achieves high velocities to 79 in./sec (2 m/sec) based on a direct drive ironless linear servo motor. High accuracy, repeatability, and functionality are guaranteed by an integrated absolute-measuring linear position encoder featuring […]
Motion Trends: Applications expand for versatile lead screws
Improvements in lead screw designs have meant screws that are increasingly competitive with other types of drive screws, including ball screws. For instance, lead screws can offer shorter lead times and better performance, all at a lower cost than other screw technologies. Quite a few lead screw manufacturers offer a range of anti-backlash options, superior […]
Motion Trends: Ball screws pack more load capacity
Continued developments in manufacturing and materials have improved ball screw performance, with the most recent generation of ball screws having greater load densities than ever before, leading to higher load capacities. High-load ball screws are being integrated into electromechanical linear actuator systems for use in applications with higher loads and more demanding environmental conditions. In […]
New linear rotary actuator features 35-mm stroke with 5-micron encoder
The LCR16 from SMAC Moving Coil Actuators provides precision Z-theta motion within one small actuator, which is suitable for pick, orient and place applications. A wide variety of LCR16 linear rotary actuators are available with either direct drive or gearbox equipped rotary units. The vacuum-built-in shaft through the rotary motor is available for some models […]
One-piece ETX linear bearing/pillow blocks suitable for use in radioactive environments
LM76 now offers one piece ETX Linear Bearing/Pillow Blocks that will not degrade in a radioactive environment. Machined from a solid block of self-lubricating ETX, linear bearing blocks have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures. Custom designed for use in a nuclear power plant these […]
New piezo driver with 1,200 W of power for fast switching applications
PI (Physik Instrumente) has released the new model E-619, a high-power piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. As a special form of electro-ceramics, piezo materials are the gold standard when it comes to speed, force, and precision in a small package. Providing sink/source currents up […]
HEIDENHAIN’s new LC 201 single-section linear encoder for absolute applications
Long machine tool axes are increasingly being equipped with linear drives, and HEIDENHAIN’s new LC 201 absolute linear scale was introduced to specifically meet those drive position feedback needs. This new scale is a single-section METALLUR tape encoder that’s ideal for use in linear motor applications that may be required to reach high acceleration levels […]
