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 high-speed, high-acceleration, zero-cogging, brushless voice coil motors provide 6.3 lb (28.2 N) of force and […]

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 belt material help eliminate or minimize belt stretch, and positive engagement between the teeth of the belt and the pulley make synchronous belts less likely […]
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 motors, or rack-and-pinion sets Linear systems in harsh environments subject to hot and humid conditions, abrasive materials, extreme loading, and corrosive chemicals. Recall that wheel-based linear guides are systems […]
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 we often think of materials and structures in terms of strength, technically, “strength” is a measure of how much force a material can withstand […]
New IoT-ready electro-mechanical actuators from Ewellix
Ewellix, formerly SKF Motion Technologies, has developed new actuators which deliver forces up to 82 kN and speeds of 1 m/sec, to provide real-time, accurate information that improves machine productivity. With the newly designed Ewellix actuators, production line upgrades are now possible without major modification of existing machine layouts. The new CASM-100 and LEMC actuators […]
What causes synchronous belt noise and how can it be reduced?
Synchronous belts are common in motion systems, providing smoother operation and better high-speed performance than chains and lacking the problems of slipping and stretching that can plague V-belts in precision applications. But one downfall of synchronous, or toothed, belts is the noise they produce. Although quieter than a chain drive, a synchronous belt can still generate noise […]
How to size a rack-and-pinion system for a precision motion axis
In a previous motion-sizing article, we reviewed how to properly specify a ballscrew-driven motion axis. Here we review how engineering teams can use a similar approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. We’ll use manufacturer software to work through the application. By Sixto Moralez • Regional motion engineer | Yaskawa America […]
How can lead screw backlash be reduced?
Backlash is an inherent property of lead screw assemblies due to the sliding motion between the screw and the nut. For some applications, a certain amount of backlash, or “play,” can be tolerated, but applications such as positioning, dispensing, or assembly often require a level of precision and repeatability that can’t be achieved if backlash […]
Ball screws feature high speed, high load capacity for machine tool applications
Featuring high-speed performance and load capacities that exceed existing full ball standards, THK’s new Type BSM ball screw is ideal for use in machine tools. The Type BSM uses a newly developed circulation structure and a large lead to meet high-speed performance demands. The DN value is 170,000, contrasted with 130,000 in conventional products. The […]
New generation of linear motor stages from Yaskawa
The Drives & Motion Division of Yaskawa America, Inc. has added the Sigma Trac II series linear servo motor stages to the Sigma-7 servo family. Sigma Trac II combines a Yaskawa SGLF2 series linear motor with linear bearings, high-resolution absolute optical scale, cable management, and optional bellows to create a turnkey linear stage. Leveraging the […]
