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.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
