This rugged unit features a new design to handle higher loads while maintaining the Compact Rail product family’s self-aligning capabilities. Compact Rail Plus is designed for demanding applications such as those involving higher loads, high speeds, fast accelerations […]
New ball screw selection tool streamlines online product selection
Thomson Industries, Inc., has launched a new online selector tool that simplifies and streamlines the purchasing experience for its precision ball screws. The tool helps design engineers zero in on the right part quickly, access a 3D model with just a click, view pricing and lead times, easily share orderable product specifications and take advantage […]
Nanopositioning controller for piezo stages boasts 270-W peak power, nanometer-level precision
A high-power version of PI’s (Physik Instrumente) E-727 family of multi-axis piezo nanopositioning controllers provides 270 W of peak power – close to 10X of the standard version. The enhanced performance is useful for dynamic, nanometer-level precision motion and positioning applications, such as FSM (fast steering mirrors) in free space optical communication and laser material […]
X-Y gantry with precision ball screw actuators
A new overhead XY gantry from IntelLiDrives is built with precision ball screw actuators. The gantry features travel lengths from 100 to 600 mm, with speeds to 100 mm/sec and resolution to 5 microns. The gantries can be motorized with stepper motors, brushless servo motor/encoders or integrated SMART motors. Contact-less end-of-travel limit sensors are also […]
THK debuts fast LM guide with speeds to 15 m/sec
With speeds reaching 15m/sec, THK’s Type FHS is said to be the fastest LM guide available on the market today. The performance of the Type FHS makes it suitable for applications requiring the fastest motion, including robot transfer devices and laser cutters. The Type FHS can be installed in horizontal, vertical, inverted, and wall-mounted orientations. […]
High precision triple-axis stage from OES
The XAB-050-XX-01 from Optimal Engineering Systems, Inc. (OES) is a low-cost solution for the precise measurement of compound angles or the rotation of an object to precise angular positions. It integrates a two-axis Alpha-Beta goniometer on top of a single-axis linear actuator. The Beta-axis has a travel range of +/- 15° with a rotation height […]
7th axis extends range for robots
igus now offers a ready-to-connect 7th axis that allows a robot to move over a distance of several meters and includes a maintenance-free drylin ZLW toothed belt axis with a corresponding adapter plate, switch cabinet, cables, and software integration. For easy integration of the axis and the robot, igus has developed two adapter kits for […]
New linear, rotary stages for high-precision positioning in vacuum applications
PI’s family of miniature micro and nanopositioning stages is expanding with the new RS-40 rotary stage and M-111 linear stages as engineers gave specific consideration to material selection, use of lubricants and coatings, and outbaking temperatures for high and ultra-high vacuum conditions. With 360-degree rotation range and 20-N load capacity, the RS-40 V7 stage boasts […]
How to pick the right drive screw
Choosing the correct drive screw type is critical to getting the best actuator performance, accuracy, and repeatability. Chris Maupin • Program Manager and Engineer | Hunt Valve Actuator Division Screw drivetrains are the most common types of electromechanical linear actuators. A screw drivetrain acts as a linear force generation system, converting a rotary torque input […]
