your reliable partner Safety brake systems for gravity-loaded axes ROBA-stop® brakes by mayr® prevent inadvertent dropping or crashing of vertical axes. ❒ Reliable safety protecting people in all operating modes ❒ Controlled operational safety due to an integrated function monitoring system ❒ Minimal braking distances due to short reaction times and high brake performance density ❒ Optimum adaptation for individual axes construction due to different brake concepts ❒ Economic and problem-free to retrofit pre-existing axes Additional measures are required to minimise the potential risk of a...

your reliable partner Modular safety brake system for a A-bearing-side servomotor attachment Highlights and Advantages ❒ DGUV (German Social Accident Insurance) test certificate: B raking device as "tried and tested component" in terms of the Category 1 acc. DIN EN ISO 13849-1 Tested Safety ❒ The leading system on the market for vertical axes with rotatory drives ❒ The axis is held safely in any position, even with a dismantled servomotor, e.g. during machine maintenance ❒ Safe braking on EMERGENCY STOP and power failure ❒ Long lifetime even after frequent EMERGENCY STOP brakings ❒ Highest...

your reliable partner ROBA®-topstop® – Designs ROBA®-topstop® with shaft design Type 899.000.0_ This brake type can be integrated into existing drives without any additional constructive work, or can be retrofitted. The output-side brake flange connection dimensions and the shaft dimensions equal the servomotor connection dimensions. A screw plug allows access to the clamping screw on the motor-side clamping hub construction. Radial forces can be absorbed by the ball bearing brake shaft, so that mounting belt pulleys and therefore operation in belt pulley drive systems is easily possible....

your reliable partner ROBA®-topstop® – Designs ROBA®-topstop® with plug-in coupling for mounting directly onto ball screw spindles Types 899.011._ _ and 899.012._ _ Type 899.01_._ _ Single circuit brake with standard output flange The brake Types 899.01_._ _ are specially conceived for direct installation onto ball screw spindles. A backlash-free, plug-in ROBA®-ES Type series shaft coupling is integrated into the brake housing to compensate for axial, radial and angular shaft misalignment. This makes separate coupling housing and shaft couplings unnecessary. The coupling hub to be mounted...

your reliable partner ROBA®-topstop® single circuit brake Technical Data Dimensions 100 120 Correlation of bore diameters d1, dependent on respective transmittable torques (without key) Preferred Bore Sizes Frictionally-locking transmittable torques (Clamping hub motor-side) Tr [Nm] Suitable for F7 / k6 Table 1 The transmittable torques for the clamping connection allow for the max. tolerance backlash on a solid shaft: Tolerance k6 / bore (d1): tolerance F7. If the tolerance backlash is larger, the torque decreases. 1) Braking torque tolerance: -20 % / +40 %, 2) Coil capacity on...
