ROBA-ES with keyways
Type 940._22._ | Nominal torque 4 - 1310 [Nm]

 		 ROBA-ES couplings are supplied either without a bore (machining by customer) or with finish bore and keyway JS9 (DIN 6885/1). There is a set screw in the hub for an axial attachment which is displaced by 180° to the keyway.
Up to size 38 aluminium is used as hub material and steel from size 42.
Preferred bores are available ex stock.
 
ROBA-ES with clamping hubs
Type 940._00._ | Nominal torque 4 - 1310 [Nm]

 		 ROBA-ES couplings with clamping hubs are designed for fast and safe assembly or disassembly. They don’t have a keyway. The tightening torque (TA) of the clamping screws must be observed in order to guarantee a reliable, friction torque transmission.
Please observe the max. permissible torques. The hubs are made of aluminium up to size 38, from size 42 on steel is used.
On request the clamping hub can be additionally designed with keyway.
 
ROBA-ES with shrink disc hub (aluminium)
Type 940._11.A | Nominal torque 4 - 1310 [Nm]

 		 The hub body consists of aluminium for this design, the ring is made of annealed, phosphated steel. The dimensions are as the P-design. Optimum true running is achieved by the symmetry, the missing keyways and radial bores. Therefore, essential higher speeds than with other hub designs are possible.
The torque is transmitted to the shaft via friction. Therefore, observe the max. torques of this shaft-hub connection.
ROBA-ES with shrink disc hub made of steel
Type 940._11._ | Nominal torque 4 - 1310 [Nm]

 		 The hub body consists of steel (oiled), the ring is made of annealed phosphated steel. This design is available in a standard version and a version to DIN 69002. The DIN version has an elastomeric element with central, standard bore and standard bore diameters in the hubs.
The DIN variation has been designed for the use in spindles with short bores and multi-spindle heads. This DIN-design combines robustness with steel hubs precision. For designs with dynamic or alternating load this design should be selected.
