ROBA®-topstop®/ROBA®-alphastop®

ROBA®-topstop®

brake module with insertable shaft coupling

These brake modules were conceived for special customer-specific applications. Depending on the respective mounting situation, these brake can be mounted directly onto a pre-installed friction flange, or they can be delivered with a mounting flange which has been specially adapted for the particular application. In this way, the brake module can be equipped with the standard clamping hub shafts and ROBA^®-ES shaft couplings, or optimally adapted to the existing mounting possibilities with special coupling constructions.

ROBA®-alphastop® Safety brake for mounting APerformance characteristics

• Complete unit with backlash-free shaft coupling

• Simple installation between the servo motor and the mounting flange

• Completely enclosed brake housing

• Design with output shaft for direct instal onto a hollow shaft gearbox

• Can be used for 100 % duty cycle

The ROBA^®-alphastop^® is a safety brake, installed between the servo motor and a bell housing. The brake toothed hub is combined with the smartflex^® backlash-free steel bellows coupling. Frictionally-locking clamping

rings ensure backlash-free torque transmission between the motor and the ball screw spindle.

The ROBA^®-alphastop^® is designed with an output shaft for direct installation onto a gearbox with a hollow shaft, meaning that the shaft coupling is unnecessary.
