Mayr Introduces New Generation of ROBA Topstop

Gravity-loaded axes in robotics applications must be safe. At the SPS 2025 in Nuremberg, Mayr Power Transmission showed the new generation of ROBA topstop safety brakes make this possible in smart environments. The compatible ROBA brake-checker module enables permanent brake monitoring. Combined with the ROBA gateway, the system delivers valuable data for proactive machine maintenance, a digital twin, and smart production environments. In addition, a practical checklist supports brake validation. For production facilities or robots with gravity-loaded axes, the protection of people and material is of the essence. Safety brakes built according to the fail-safe principle – i.e., applied in de-energized condition – provide the foundation here. The ROBA topstop from Mayr Power Transmission holds the loads in position reliably and prevents uncontrolled movements in case of power outages or emergency stops. As they are placed between the motor and the output, the brakes can be retrofitted in existing constructions – a solution that reduces effort and costs. Robust construction ensures reliability For day-to-day industrial operations, the ROBA topstop braking system is equipped as an independent, compact module. O-rings at the interfaces ensure reliable sealing against dust and moisture – the brakes achieve IP66 protection as standard. The vertical axes remain secured even when the drive is dismantled, which is advantageous during maintenance and transport. Thanks to the adaptable flange dimensions, the system can be easily integrated into existing constructions.
