Linear ball bushings are one of the few interchangeable product types in linear motion, with industry-standard sizes and styles, so that a product from one manufacturer can often be substituted with a product from another manufacturer that has very similar dimensions and technical specifications. And most linear bushing manufacturers offer several product lines that are […]
Automated farm equipment uses rugged linear components
Precision agriculture is the discretization of farming — defined as the analysis of highly variable (and often unpredictable) landscapes to: • Break larger agricultural fields into smaller discrete sections • Quantify the characteristics (such as soil composition, light, and seed spacing) of each section • Adapt to the variations between sections with automated farm equipment […]
How to protect ball screws in harsh environments
Harsh environments can wreak havoc on motion system components — especially rolling element systems such as linear guides and ball screws. And while protective devices such as rail covers, wipers, and scrapers are widely available for linear guides, protecting ball screws in harsh environments is a bit more tricky. But despite being more difficult to […]
New multi-axis stages: Driving dynamics in one plane for top performance
Having all of a stage’s driving dynamics in one plane can prevent problematic reaction torques on sensitive workpieces … and maximize machine performance for demanding motion applications. By Mathys te Wierik • Lead system engineer Jan Willem Ridderinkhof • Manager of R&D and engineering | PM B.V. High-end mechatronic motion solutions have proliferated as various […]
New conveyor clamping module option from Dorner
Dorner is now offering a Clamping Module on its FlexMove conveyor system that gives users the ability to hold back or pace products for accumulating applications. The Clamping Module is ideal for totes, boxes, bottles and square, round and rectangular containers. As products pass through the Clamping Module, pre-programmed photo sensors trigger a pneumatic-clamping actuator […]
Hexapods precisely jostle cameras during image-stabilization testing
The six-axis parallel-kinematics systems known as hexapods excel in motion simulation and testing of mechanical and drive systems, multi-dimensional position sensors, and (the focus of this article) image-stabilization designs for cameras and video equipment. By Doris Knauer • Project Manager — Industrial Automation | Physik Instrumente (PI) Modern camera systems are capable of astounding feats, […]
What to consider when specifying a linear slide
Here are some considerations when specifying a linear slide for a new or existing application. By Mike Quinn • LM76 When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this: Does an off-the-shelf linear slide (or […]
What are fixed and floating bearings in the context of linear motion?
There are two instances when the terms “fixed bearing” and “floating bearing” are used in linear motion: to describe the support bearings used on ball and lead screws, and to describe linear guides mounted in parallel. And while the meanings of the terms are the same in both situations, their applications are different in each […]
ElectroCraft expands AxialPower family of linear actuators with the APES 17
ElectroCraft has recently expanded the AxialPower enhanced series of linear actuators to include a new high-performance 42mm (NEMA 17) frame size. This new linear actuator is highly configurable and: • Is available with a variety of imperial or metric leadscrew options • Achieves resolutions of 0.006 mm to 0.050 mm per step • Delivers output […]
LinX M-Series electric actuators from ANCA Motion offer direct replacement of pneumatic cylinders
Pneumatics (and compressed air) are indispensable in many industrial applications. They’re cost-effective and easy-to-understand technologies that are rugged enough to run in even very challenging environments. The problem is that some facilities can spend up to 30% of their electricity bill on generating compressed air. Because pneumatic actuators for linear motion (which have been an […]
