New 3-axis linear voice coil actuator stage from Moticont
Moticont has released a new three-axis XYZ linear actuator, the XYZ-10. The X and Y axis of the actuator each has 0.97 in. (24.6 mm) of travel and the Z axis has a stroke of 0.500 in. (12.7 mm). The … [Read More...]
What’s the best timing belt tooth profile for high-speed applications?
Synchronous belts (also referred to as timing belts) are used in a wide range of power transmission and transport applications that require good positioning accuracy. Tensile cords molded into the … [Read More...]
What you need to know about corrosion-resistant linear guides
Recirculating ball and roller guides are the backbone of many automation processes and machines, thanks to their high running accuracy, good rigidity, and excellent load capacities — characteristics … [Read More...]
New profiled linear guideways handle loads up to 150 tons
SCHNEEBERGER Inc. has expanded its MONORAIL MR profiled linear guideway series with its new MR 30 MONORAIL 30-mm rail and cross roller cartridge. The MONORAIL MR series moves especially heavy … [Read More...]
Linear Motion Tips – Top 10 articles of 2019
Linear motion publications are typically dominated by topics related to linear guides, ball screws, and lead screws. But looking back at this site's most-viewed articles in 2019, it's obvious that … [Read More...]
Stepper motor torque and speed characteristics explained
Stepper motors have different torque-speed characteristics depending on whether the motor is starting/stopping or already running. These characteristics are depicted in two curves on the motor's … [Read More...]
Gantry motion system for inspection, assembly, and 3D printing
Physik Instrumente’s (PI) new compact XY/XYZ gantry motion system provides overhead motion for industrial automation applications in assembly, pick-and-place, alignment, inspection, and custom 3D … [Read More...]
Part 2 – What is racking in gantry systems, and how can it be avoided?
In Part 1 of this post, we looked at various methods of driving the X axes in gantry systems and how the drive method can influence the gantry's tendency to experience racking. Another factor that can … [Read More...]
Stepper-, servo-based 400-mm hollow core motorized rotary stages from OES
OES (Optimal Engineering Systems, Inc.) has added two larger rotary stages to their AY110 Series of motorized rotary stages. The low-profile 400 mm AY110-400-01 (step motor driven) and AY110-400-02 … [Read More...]
What is racking in gantry systems, and how can it be avoided? (Part 1)
Gantries differ from other types of multi-axis systems (such as Cartesian robots and XY tables) by using two base (X) axes in parallel, with a perpendicular (Y) axis connecting them. While this dual … [Read More...]
Review of linear actuation complemented by guide wheels
Linear bearings based on steel guide wheels often complement motor-based linear actuation in two challenging application types: Long-stroke linear-motion axes as those driven by belts, linear … [Read More...]

Wire-actuated encoder features 12-m measuring length
The new SG121 wire-actuated encoder from SIKO features measuring lengths up to 12 m with an installation depth of just 70 x 85 x 105 mm. The robust aluminum housing, coupled with impact-resistant … [Read More...]
Mechanical properties of materials: stiffness and deflection
In a previous post, we looked at the stress-strain curve and its relationship to various aspects of material strength — tensile strength, yield strength, and fracture strength, for example. And while … [Read More...]
Boosting productivity with the right direct-drive motor and linear-motor feedback
Feedback options for linear motors and direct-drive torque motors abound. The most common employ optical, magnetic, capacitive, or inductive measurement. Here we explain how the key application … [Read More...]
