mayr ROBA®-alphastop® mayr ROBA®-alphastop® Safety brake for vertical and slant feed axes in machine tools Characteristics • Easy installation between servo motor and mounting flange • Completely enclosed around outer diameter • Complete unit with backlash-free coupling • Insulation class F, designed for 100 % duty cycle Concept The ROBA®-alphastop® is a safety brake, installed between the servo motor and a bell housing (see Figs. 1 and 2). The brake gear hub is combined with smartflex®, a backlash-free metal bellows coupling. Frictionally locked clamping rings ensure backlash-free torque transmission...

ROBA®-alphastop® Installation Instructions Installation Conditions ● he permitted shaft misalignments must not under any T circumstances be exceeded! ● he axial run-out deviation of the screw-on surface to the shaft T may not exceed the permitted axial run-out tolerance of 0,1 mm according to DIN 42955. Larger deviations can lead to a drop in torque, to continuous slipping of the rotor (2) and to over-heating. ● lease select the tolerances of the hub (1, Size 100) and the P shaft so that the hub toothing (1, Size 100) is not widened. Widening of the toothing leads to the rotor (2) jamming on...

mayr ROBA®-alphastop® mayr ROBA®-alphastop® Further Options ROBA®-topstop® Modular Safety System for A-Bearing-side Servo Motor Attachment ROBA®-topstop® safety brakes were developed for operation in gravity-loaded axes. They hold the axes safely in any position, even if the servo motor is dismantled, for example during maintenance work. Due to their fitted flange dimensions, ROBA®-topstop® safety brakes can be easily integrated into pre-existing constructions between the servo motor and the counterflange. Five standard sizes for braking torques between 12 to 400 Nm can be delivered at short...
