The dynamic safety brakes in the ROBA®-linearstop series work according to the fail-safe principle. The braking force is provided by pressure springs and transferred backlash-free via a conical surface onto a collet. This collet clamps the brake rod continuously, without changing its position. In closed position, the brake is able to withstand loads in both directions of motion. Dynamic braking actions can be achieved from speeds with a maximum of 2 m/s.
Safety brakes of the ROBA®-linearstop series are designed for dynamic braking applications and can be mounted directly onto standard cylinders according to DIN ISO 15552.
Dynamic stops were tested according to the Trade Association testing requirements on the mayr®-Drop Test Stand. In compliance with the Trade Association requirements, the tested elements are switched a million times statically and load-free, and a million times with load assumption. At every thousandth switching, they are braked dynamically from motion. The ROBA®-linearstop brake unit achieved 30,000 dynamic brake applications in fatigue tests with a maximum load and is therefore substantially better than the Trade Association testing requirement, which only stipulates 1,000 dynamic brake applications.
ROBA®-linearstop safety brakes can be mounted directly onto standard cylinders according to DIN ISO 15552. They can also be integrated simply, quickly and without complicated adjustment into different drive constellations. In contrast to other linear braking systems, the ROBA®-linearstop does not have to travel on the carriage. Supplying the pneumatic lines is therefore simplified. The brake can be screwed to a static machine component. The cylindrical piston rod is guided through the central bore of the brake and connected to the carriage of the linear drive.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
