Over the past three decades, Bosch Rexroth’s portfolio of ready-to-install linear axes has been further developed on an ongoing basis. In response to customer requirements, it now focuses on electrification and connectivity. With today’s linear motion technology components in combination with sensors, electronics and software, the company now offers mechatronic solutions for the Factory of […]
How to make sure you get the right linear bushing interchange
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 […]
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 […]
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 […]
Tips for mounting linear ball bearings: Pillow block housings
Linear ball bearings and round shafts are often used in applications that call for ease of use and simple mounting requirements. For example, where profiled rail guides require full support along their length, linear ball bearings, or bushings, can be used in many applications with shafts that are supported only at their ends. However, unlike […]
Just for fun (and safety): Pandemic-inspired inventions
Necessity is the mother of invention, as the saying goes. And so has been the case since the beginning of the COVID-19 pandemic. Although much of the focus on product development and innovation since the pandemic began has been centered around treatment and critical care technologies such as ventilators, some of these pandemic-inspired inventions are […]
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 from a […]
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 […]
PM develops ultra-low-profile rotary table bearings
Lower costs by using the rotary table bearing FMB. The compact designed FMB table bearing has been developed for high precision rotary motion. It reduces the cost compared to other rotary bearings since fewer components with less tolerance are used necessary for installation offering easy installation of the bearings and reducing the overall costs. The […]
What is a linear variable differential transformer (LVDT)?
In previous articles, we’ve covered a variety of technologies for measuring linear position: magnetic and optical encoders, magnetostrictive sensors, and even measuring systems integrated into linear guide systems. Another technology for measuring absolute linear position is the linear variable differential transformer (LVDT). A linear variable differential transformer is an induction-based measuring system that consists of […]
