With bearing supported clamping hub shaft
Type 899.000.0_ | Brake torque 12 - 160 [Nm]

 		 This brake type can directly be integrated or retrofitted in existing drives without appreciable additional technical expenditure. The brake flange and shaft connection dimensions on the output side correspond to the respective servo motor dimensions.

A hole above the terminal box allows access to the tightening screw of the clamping hub design on the motor side.

Radial forces can be absorbed via the bearing supported shafts, so that the mounting of belt pulleys and the application in belt driven drive system is possible without problems.
 

With integrated, plug-in shaft coupling (motor side: clamping hub)
Type 899.011.__ | Brake torque 12 - 160 [Nm]

 		 The brake types 899.01_._ _ are especially designed for the mounting at ball screws spindles.

With a ROBA-ES backlash free shaft coupling, which compensates for axial, radial and angular shaft misalignments integrated into the brake housing, the application of this ROBA-topstop unit removes the necessity for separate coupling distance pieces and shaft couplings.

The standard motor shaft mounted coupling hub is the ROBA-ES clamping hub type or shrink disc hub, whereas the coupling hub on the output side is safely connected with the spindle shaft via a shrink disc clamping connection.

The short brake construction length does not require any additional space in comparison to the traditional coupling housing designs.

With integrated, plug-in shaft coupling and
EAS-smartic torque limiter
Type 899.013.__ | Brake torque 12 - 160 [Nm]

 		 This ROBA-topstop brake is complete with an torque limiting clutch in addition to the integral ROBA-ES shaft coupling.

The EAS-smartic clutch disengages when the preset limiting torque is exceeded and the drive torque drops immediately. An integral inductive switch indicates the overload. The brake is engaged and the input supply is switched off. The gravity-loaded axis is safely held even with a disengaged clutch.

Reliable torque overload protection and safely held axis offer maximum protection for persons and machine.
 

Brake module with clamping hub shaft
Type 899.100.0_ | Brake torque 12 - 160 [Nm]

 		 Brake modules of the Type series 899.1_ _._ _ have been designed for special customised mounting applications. Dependant on the corresponding mounting situations these brakes can be mounted directly to an already existing friction flange face or supplied with an adapter flange to suit the specific application.

This brake module, equipped with the standard clamping hub shafts and ROBA-ES shaft couplings or with a special customised design, can optimally be adapted to existing mounting situations.

Redundant dual circuit brake with clamping hub shaft in bearing
Type 899.200.01 | Brake torque 2 x 12 - 2 x 100 [Nm]

 		 The dual circuit brake with clamping hub shaft in bearing is equipped with two brake circuits acting independently of each other. Each brake circuit is individually electrically controllable.

Dependant on the single circuit brake system the operating condition of each brake circuit separately scanned and signalled.

Consequently this redundant brake system fulfils all requirements of the dangerous category 3.
